The Shimano FD-5700 [paid link] front derailleur, part of the 105 5700 series, is a reliable and precise shifting component designed for road cycling. However, like all mechanical parts, it requires regular care to avoid premature wear. Riders who neglect adjustment, cleaning, or lubrication often experience noisy shifting, excessive friction, or shortened service life. This guide provides detailed, technical instructions on how to keep your FD-5700 [paid link] front derailleur in top condition for years.

Understanding the FD-5700 Front Derailleur

The FD-5700 [paid link] is designed for 2×10-speed drivetrains and is available in both braze-on and clamp-band versions. It features a wide pivot design for improved stiffness and accurate front shifting. Despite its durability, improper maintenance can lead to wear on the pivot points, cage plates, and spring mechanism. Recognizing these vulnerabilities helps you understand where to focus your preventive care.

Tools Required

  • 5 mm hex wrench
  • Phillips screwdriver
  • Torque wrench [paid link]
  • Cable cutters
  • Bike-specific degreaser
  • Chain lubricant
  • Clean microfiber cloths

Correct Installation to Prevent Early Wear

Proper installation is the first step in preventing premature derailleur failure. The derailleur cage must sit 1–3 mm above the large chainring and align parallel to the chainrings. Any misalignment creates additional friction, which accelerates wear on the cage plates.

Torque specifications are also critical. The braze-on fixing bolt should be tightened to 5–7 Nm. Under-tightening causes the derailleur to slip, while over-tightening can stress the mounting surface. Both scenarios contribute to uneven wear.

Cable Tension and Routing

Incorrect cable tension is one of the leading causes of accelerated wear on the FD-5700. Overly tight tension puts unnecessary strain on the derailleur spring, reducing its lifespan. Too little tension, on the other hand, forces riders to overshift, which grinds the chain against the cage.

Ensure the cable runs smoothly through the frame guides without excessive bends. A frayed or corroded cable should be replaced immediately, as damaged strands can dig into the derailleur’s cable anchor and shorten its service life.

Cleaning and Lubrication Practices

The FD-5700 operates best when free of grime and adequately lubricated. Dirt buildup around the pivot points increases friction, leading to sluggish shifting and accelerated pivot wear.

Use a bike-specific degreaser to clean the derailleur thoroughly, making sure to reach all pivot points and the inner and outer cage plates. After drying, apply a light lubricant directly to the pivots to protect against corrosion. Avoid over-lubricating, as excess oil attracts dirt and can cause more harm than good.

The derailleur cage plates should also be kept clean to minimize chain rub. A microfiber cloth with a small amount of degreaser is effective for wiping away residue from the inner cage.

Chainline and Drivetrain Compatibility

A poorly maintained drivetrain can indirectly shorten the lifespan of the FD-5700. Cross-chaining—using the big chainring with the big cog or the small chainring with the small cog—creates side pressure on the derailleur cage. Over time, this can cause uneven wear on the plates and lead to noisy shifting.

Using the correct bottom bracket spacing and chainline ensures smoother operation. Since the FD-5700 is optimized for Shimano’s 10-speed road drivetrains, mixing it with incompatible cranksets or chains should be avoided.

Avoiding Common User Mistakes

Many premature failures are due to rider habits rather than mechanical faults. Avoid the following mistakes:

  • Shifting under heavy load, which stresses the cage and pivots.
  • Ignoring limit screw settings, leading to over-travel and cage deformation.
  • Allowing dirt and road salt to accumulate without regular cleaning.

Consistent attention to these details prevents unnecessary strain on the derailleur.

Seasonal Inspection Schedule

To extend the life of your FD-5700, adopt a seasonal maintenance routine. During peak riding months, inspect the derailleur at least once every four weeks. Check the limit screws, cable tension, and cage alignment. In the off-season, perform a deeper cleaning and lubrication, and replace worn cables or housing before storage.

Recognizing Early Signs of Wear

Catching issues early helps avoid costly replacements. Common warning signs of wear on the FD-5700 include:

  • Increased play at the pivot points.
  • Chain rub that persists despite proper adjustment.
  • Stiff cage movement due to internal corrosion.
  • Frayed shift cables at the anchor point.

Addressing these problems immediately prevents further damage.

Conclusion

The Shimano FD-5700 front derailleur can deliver years of reliable performance when properly maintained. By ensuring correct installation, managing cable tension, cleaning and lubricating regularly, and avoiding poor shifting habits, you can prevent premature wear. A seasonal inspection schedule further safeguards the component, extending its service life and preserving crisp, accurate shifting. Investing time in care and maintenance ensures that your FD-5700 remains a dependable part of your drivetrain for many seasons of riding.

The Shimano FD-5700 [paid link] front derailleur, part of the 105 5700 groupset, is a reliable and widely used component. However, incorrect installation, adjustment, or maintenance can lead to poor shifting performance, premature wear, and even damage to the derailleur or chainrings. Riders often underestimate how sensitive the FD-5700 [paid link] is to small errors, and this is where problems begin. This guide covers the most common mistakes to avoid when working with your Shimano FD-5700 [paid link] front derailleur and how to ensure optimal performance.

Incorrect Clamp Height and Angle

One of the most frequent mistakes is setting the derailleur cage at the wrong height above the large chainring. The FD-5700 requires a clearance of about 1–3 mm from the tallest tooth of the big ring. Too much gap reduces shifting precision, while too little may cause the cage to strike the chainring.

Additionally, the derailleur cage must be aligned perfectly parallel with the chainrings. Even a slight misalignment causes chain rub in multiple gears and sluggish upshifts. Riders often overlook this step, assuming the eye can judge alignment accurately. A careful adjustment using the chainring edge as a reference is essential.

Improper Cable Tension

Cable tension is critical for precise shifting. A common mistake is either under-tensioning or over-tensioning the cable during installation. Insufficient tension results in the derailleur failing to shift onto the large chainring, while excessive tension causes chain rub and premature wear of the cable anchor bolt.

The FD-5700 has a specific tension sweet spot, and adjustments should be made using the barrel adjuster on the downtube shifter or inline adjuster. Riders often tighten the cable too much during the initial clamp, leaving no room for fine-tuning. Always start with a snug but not overtightened cable and then dial in tension gradually.

Neglecting Limit Screw Settings

Incorrect limit screw adjustment is another major source of derailleur issues. The FD-5700 has two limit screws—one for the inner stop and one for the outer stop. If the inner limit screw is set too loose, the chain may drop into the bottom bracket shell. If it is too tight, the derailleur will not shift onto the small ring properly.

Similarly, setting the outer limit incorrectly can cause the chain to overshift and fall off the large chainring, or it can prevent the derailleur from reaching the big ring altogether. Riders often confuse these screws with tension adjustments, leading to endless frustration.

Cross-Chaining Without Awareness

While Shimano designed the FD-5700 to handle modern gear ranges, extreme chainlines still create problems. Shifting into the big chainring while riding on the largest cassette cog, or the small chainring with the smallest cog, leads to chain rub on the derailleur cage. Many riders misinterpret this as a set-up fault, when in fact it is an expected limitation of drivetrain design.

Continued riding in cross-chained gears accelerates wear on the derailleur cage and chain. Proper gear selection and an understanding of drivetrain limitations are essential to avoid unnecessary stress on the FD-5700.

Overlooking Cable Routing and Housing Condition

Another mistake lies in ignoring cable routing and housing quality. The FD-5700 requires smooth, low-friction cable movement to shift accurately. Kinks, dirt, or frayed cables add drag, which prevents the derailleur from returning smoothly to the small chainring.

Many home mechanics reuse old housing or fail to trim housing to the correct length, resulting in excess bends that slow cable movement. Fresh, well-lubricated cables with correctly cut housing ends are crucial for maintaining consistent shifting performance.

Failure to Maintain and Lubricate the Pivot Points

The FD-5700 front derailleur features multiple pivot points that must move freely. Riders often neglect lubrication, allowing dirt and moisture to build up. Over time, this creates stiff pivots that make the derailleur resistant to spring return.

Regular cleaning and applying a drop of light oil to each pivot helps the derailleur maintain crisp movement. Skipping this step can lead to sluggish shifting and eventually force replacement of the derailleur long before its natural service life ends.

Using Incompatible Chainrings or Cranksets

The FD-5700 was designed to work with Shimano 10-speed chainrings, and using incompatible components can cause serious shifting issues. Many riders attempt to pair the derailleur with non-Shimano or mismatched chainring sets, which often have different tooth profiles and spacing.

As a result, the derailleur may never shift correctly, regardless of how carefully it is adjusted. Sticking to the intended chainring size range—typically 50–53T outer rings and 34–39T inner rings—is essential for proper function. Mixing non-compatible drivetrains is one of the costliest mistakes because it often requires buying new parts to correct.

Overtightening the Clamp Bolt

Overtightening the derailleur clamp bolt can deform the frame’s braze-on tab or damage the derailleur body itself. Many riders mistakenly assume that tighter is always better, but this can compromise both the frame and component integrity.

Shimano specifies a torque value of 5–7 Nm for the FD-5700 clamp. Using a torque wrench [paid link] ensures secure installation without the risk of damage. Skipping this detail is a common mistake among home mechanics and often leads to expensive repairs.

Ignoring Chainline Compatibility

The FD-5700 works best with a chainline of 43.5 mm, matching Shimano 10-speed road cranksets. Installing it with an out-of-spec crank or bottom bracket can cause constant rub or prevent full shifts. Riders sometimes attempt to pair it with compact or non-standard drivetrains without considering chainline specifications.

Even if the derailleur is perfectly adjusted, a poor chainline forces it to work outside its intended range. This mistake reduces efficiency and shortens the lifespan of the component.

Conclusion

The Shimano FD-5700 front derailleur is a precise component that demands careful installation and maintenance. Avoiding mistakes such as incorrect clamp positioning, poor cable tension, neglected pivot lubrication, and incompatible drivetrain setups will save riders from frustrating shifting problems and costly replacements. With proper attention to detail, the FD-5700 can deliver years of reliable and accurate performance.

Understanding the technical aspects of upgrading this front derailleur is essential to avoid poor shifting, premature wear, or costly mistakes.

Understanding the Shimano FD-5700 Front Derailleur

The FD-5700 [paid link] was released as part of Shimano’s 105 5700 series, offering trickle-down technology from Ultegra and Dura-Ace groupsets. It features a wide-link design for improved rigidity and more accurate shifting, as well as compatibility with 10-speed road drivetrains. This model is available in both braze-on and clamp-band versions, making it adaptable to a wide range of frame designs.

When considering an upgrade, it is critical to recognize that the FD-5700 [paid link] is optimized for 10-speed chainrings and specific cable pull ratios. Any replacement must match these technical specifications to deliver smooth shifting.

Compatibility Factors to Consider Before Upgrading

Upgrading a front derailleur is not as simple as swapping parts. Shimano front derailleurs are designed to work within specific drivetrain ecosystems. To determine if an upgrade is feasible, several compatibility factors must be checked:

Drivetrain Speed Matching

The FD-5700 is engineered for 10-speed systems. If the rest of your groupset is also 10-speed, you must replace it with another 10-speed front derailleur. Attempting to pair it with an 11-speed or 12-speed derailleur will cause issues due to different chain widths, cage shaping, and cable pull requirements.

Chainring Size and Capacity

The FD-5700 supports a maximum capacity of 16 teeth and is designed for compact (50/34T) and standard (53/39T) chainring combinations. Any upgrade must support the same range. Using an incompatible derailleur may cause chain rub or incomplete shifts between rings.

Cable Pull and Actuation Ratio

Shimano’s cable pull changes between generations. The FD-5700 uses the actuation ratio designed for 10-speed road shifters of its era. Upgrading to an 11-speed or newer derailleur will mismatch the pull ratio, leading to sluggish or overshifted gear changes.

Mounting Style

The FD-5700 comes in braze-on and clamp versions. An upgrade must match your bike’s frame design, or an adapter may be required. Choosing the wrong mount will prevent correct installation.

Upgrade Options for the FD-5700

If your current derailleur is worn or damaged, the most straightforward upgrade is a like-for-like replacement with another Shimano 105 FD-5700 front derailleur. This ensures full compatibility with your existing drivetrain. However, if you want to improve performance while keeping your 10-speed setup, you may consider the following alternatives:

  • Shimano Ultegra FD-6700 [paid link]: This is the 10-speed Ultegra front derailleur, offering stiffer construction and slightly better shift performance. It is fully compatible with 10-speed Shimano road drivetrains and serves as a performance-oriented upgrade.
  • Shimano Dura-Ace FD-7900 [paid link]: This high-end 10-speed derailleur offers the lightest weight and most precise shifting available for its generation. It is compatible with the FD-5700 drivetrain but comes at a higher cost.
  • Shimano Tiagra FD-4600 [paid link]: This is a budget-friendly 10-speed alternative that will work with Shimano 105 shifters. While not as refined, it can serve as a reliable replacement.

Upgrading to 11-speed or newer derailleurs (such as FD-5800 [paid link], FD-7000, or FD-R8000 [paid link]) is not recommended unless you plan to overhaul the entire drivetrain to 11-speed, including shifters, chain, and crankset.

Best Practices When Upgrading the FD-5700

To ensure the best outcome when replacing or upgrading your Shimano FD-5700, several best practices should be followed:

  • Always match derailleur speed to the drivetrain speed. Mixing 10-speed and 11-speed parts will compromise shifting performance.
  • Verify the maximum chainring size and total capacity before installing an alternative derailleur.
  • Use correct cable routing and tension settings as specified by Shimano. Even compatible derailleurs will shift poorly if adjusted incorrectly.
  • Replace worn chains and chainrings when upgrading the derailleur. Old components can cause skipping or ghost shifts, even with a new derailleur.
  • Stick with Shimano models for maximum compatibility. Mixing brands can lead to inconsistent cable pull ratios and shifting problems.

When a Full Drivetrain Upgrade Makes Sense

If you are considering a major performance upgrade beyond the FD-5700, moving to an 11-speed system such as Shimano 105 5800 or newer may be worthwhile. This requires new shifters, chain, cassette, crankset, and both derailleurs. Although more costly, this provides access to modern ergonomics, improved cable routing, and significantly smoother shifting.

For riders who prefer to maintain their 10-speed setup, however, replacing the FD-5700 with a compatible 10-speed model remains the best solution for reliable and cost-effective performance.

Conclusion

Upgrading the Shimano FD-5700 front derailleur is possible, but it requires careful attention to drivetrain compatibility. The best upgrade paths remain within Shimano’s 10-speed ecosystem, with Ultegra FD-6700 [paid link] and Dura-Ace FD-7900 [paid link] offering performance gains. Riders should avoid mixing 10-speed and 11-speed derailleurs unless they plan to upgrade the entire drivetrain. By following compatibility rules and installation best practices, you can keep your Shimano 105 5700 front derailleur system running smoothly for years to come.

The Shimano FD-5700 [paid link] front derailleur is part of the 105 5700 groupset, designed to deliver reliable and precise shifting for road cyclists. However, if your derailleur feels sluggish, noisy, or inconsistent, the issue usually lies in its setup or wear rather than a design flaw. This guide explains why the Shimano FD-5700 [paid link] front derailleur may feel off and how to correct it for smooth, accurate shifting.

Understanding the Shimano FD-5700 [paid link] Front Derailleur

The FD-5700 is a braze-on or clamp-style double front derailleur optimized for 10-speed drivetrains. It uses a wide-link design to improve stiffness and shifting response. Despite this, small errors in alignment, cable tension, or component compatibility can lead to poor performance. Recognizing the root causes of misalignment and poor shifting is essential before making adjustments.

Common Reasons the FD-5700 Feels Off

Several factors can cause the Shimano FD-5700 to perform below expectations. These include incorrect installation, poor cable routing, and general wear. Identifying these issues early ensures optimal drivetrain function.

  • Cage Alignment Issues: If the derailleur cage is not parallel to the chainrings, shifting will feel rough, especially from the small to the large chainring.
  • Cable Tension Problems: Low tension results in hesitant shifts, while excessive tension can push the chain too far, creating noise or overshifting.
  • Limit Screw Misadjustment: Incorrectly set limit screws can restrict movement, prevent full shifts, or allow the chain to overshoot.
  • Chainring Wear: Worn or mismatched chainrings can cause chain rub or hesitation, making the derailleur feel unresponsive.
  • Dirty or Dry Mechanism: Lack of lubrication or accumulated grime within the pivots can cause stiffness in derailleur movement.

How to Instantly Improve Performance

Improving the performance of the Shimano FD-5700 requires precise adjustments and targeted maintenance. The following steps will restore smooth operation and eliminate most shifting issues.

Check and Correct Derailleur Positioning

The derailleur cage must sit at the correct height and angle. For the FD-5700, the outer cage plate should be 1–3 mm above the tallest chainring teeth. The cage must run perfectly parallel to the chainrings. Even a slight rotation can cause rubbing and poor shift quality. If the cage is misaligned, loosen the mounting bolt, reposition the derailleur, and retighten securely.

Set Cable Tension Properly

Cable tension is critical for crisp front shifting. Begin with the barrel adjuster fully turned in, then back it out slightly. Pull the cable taut while fastening it at the anchor bolt. Fine-tune tension using the adjuster: too loose will delay shifting to the large ring, while too tight may force the chain to overshift and rub on the outer cage plate.

Adjust the Limit Screws Accurately

The FD-5700 uses two limit screws marked “L” for the low gear (inner chainring) and “H” for the high gear (outer chainring). Proper adjustment prevents the chain from dropping off either side.

  • Set the low limit screw so the cage sits close to the chain when on the small ring and largest rear cog.
  • Adjust the high limit screw so the cage clears the chain on the large ring and smallest rear cog without overshooting.

Precise adjustment ensures smooth shifts and protects the drivetrain.

Inspect and Maintain the Mechanism

The FD-5700 operates through several pivot points that must move freely. Apply a light lubricant to these pivots while wiping away dirt and old grease. A sluggish derailleur is often the result of dried lubrication. Regular cleaning ensures smoother action and longer component life.

Check Chain and Chainring Compatibility

The Shimano FD-5700 is designed for 10-speed systems and works best with Shimano 105 5700 chainrings. Using incompatible chainrings or mixing components from different generations may cause shifting inconsistencies. If your chain is stretched or worn, replacement is necessary for smooth engagement.

When to Replace the FD-5700

If adjustments and lubrication fail to improve performance, the derailleur itself may be worn. Excessive play in the pivots or a bent cage can render the component unreliable. In such cases, replacement with another FD-5700 or a compatible Shimano 10-speed derailleur is the best option to restore performance.

Conclusion

The Shimano FD-5700 front derailleur is a capable and precise shifting component when set up correctly. If it feels off, the problem typically comes down to alignment, cable tension, or wear. By ensuring the derailleur is correctly positioned, adjusting cable tension, fine-tuning the limit screws, and maintaining clean pivots, riders can instantly improve shifting performance. For long-term reliability, keep the drivetrain clean, replace worn components, and ensure compatibility across the groupset.

The Shimano FD-5700 [paid link] front derailleur, part of the 105 10-speed groupset, is a reliable component designed for precise and efficient shifting. Over time, the front derailleur cable can stretch, fray, or corrode, leading to sluggish or inconsistent shifting. Replacing the cable is a key maintenance task that restores crisp performance and ensures your drivetrain continues to operate smoothly. This guide provides a detailed, step-by-step explanation of how to replace the cable on your FD-5700 [paid link] front derailleur, covering tools, installation, adjustments, and optimization.

Tools Required

  • 5 mm hex wrench
  • Cable cutters
  • New front derailleur cable (stainless steel recommended)
  • Cable end cap
  • Small flat-head screwdriver
  • Torque wrench [paid link] (optional but recommended)

Preparing the Bike for Cable Replacement

Before beginning, shift the chain onto the small chainring and smallest rear cog. This position reduces cable tension, making removal easier. Inspect the existing housing for wear, kinks, or cracks. If the housing is damaged, replacing it at the same time as the cable is highly recommended to prevent premature cable wear and ensure smoother shifting.

Cleaning the derailleur pivot points with a degreaser and lightly lubricating them before installation will also help improve performance and extend component life.

Removing the Old Cable

Begin by loosening the pinch bolt on the FD-5700 [paid link] derailleur using a 5 mm hex wrench. This will release the tension on the existing cable. Pull the cable free from the derailleur’s clamp plate. Next, move to the shifter and push the lever to its lowest gear position. Carefully pull the old cable out of the shifter body. If frayed ends are present, cut them cleanly with cable cutters to prevent damage to the shifter’s internal routing. Dispose of the old cable properly.

Installing the New Cable

Insert the new cable into the shifter body, ensuring it follows the designated path without kinks. Shimano 105 shifters have a clearly marked entry point, so carefully guide the cable through until it exits near the bottom bracket area. Thread the cable through the existing housing, checking for smooth passage. If resistance occurs, the housing may need to be replaced.

Once the cable exits the housing, route it along the frame guides toward the FD-5700 derailleur. Position the cable under the derailleur clamp plate according to Shimano’s specification, with the correct orientation to prevent slippage under tension. Pull the cable snug, then tighten the pinch bolt securely with a 5 mm hex wrench. Using a torque wrench [paid link], aim for Shimano’s recommended torque range of 6–7 Nm for the pinch bolt.

Setting Cable Tension

Proper cable tension is essential for reliable shifting. With the cable installed, actuate the shifter to move the derailleur between positions. If shifting feels slow or incomplete, slightly increase tension using the barrel adjuster located at the shifter or inline adjuster, if fitted. Conversely, if the derailleur overshifts past the large chainring, reduce tension incrementally until the cage aligns correctly.

The FD-5700 derailleur relies on precise cable pull ratios, so adjustments should be small and deliberate to avoid overcompensating.

Adjusting Limit Screws

Once the new cable is tensioned, fine-tuning the limit screws ensures that the derailleur guides the chain without overshifting. The FD-5700 uses two screws: the low limit screw controls inward travel toward the small chainring, while the high limit screw controls outward travel toward the large chainring.

Shift the chain to the small chainring and largest rear cog. Adjust the low limit screw until the inner cage plate sits 0.5–1 mm from the chain without rubbing. Then, shift to the large chainring and smallest rear cog. Adjust the high limit screw so the outer cage plate also clears the chain by 0.5–1 mm. These settings prevent chain drop and rubbing during gear changes.

Finishing the Installation

After adjustments are complete, trim the excess cable, leaving around 2–3 cm beyond the pinch bolt. Crimp a cable end cap to prevent fraying, which can interfere with shifting and cause injury during future maintenance. Double-check all adjustments by shifting through the full range of gears. Smooth, crisp transitions across chainrings indicate a successful installation.

Optimizing Performance After Cable Replacement

For the FD-5700 front derailleur, regular inspection and maintenance after a cable replacement help preserve performance. Recheck tension after the first few rides, as new cables can stretch slightly under load. Applying a light lubricant to the cable where it enters the housing can also reduce friction and extend cable life. Riders who frequently ride in wet or muddy conditions should consider upgrading to sealed cable housing systems for enhanced protection against contamination.

Common Mistakes to Avoid

Improper routing of the cable under the derailleur clamp plate is one of the most common errors during installation. Incorrect orientation can cause slippage or insufficient clamping force, leading to poor shifting. Another mistake is failing to replace worn housing along with the cable, which can negate the benefits of a new cable. Over-tightening the pinch bolt can also damage the cable or clamp plate, reducing long-term reliability.

Conclusion

Replacing the cable on your Shimano FD-5700 front derailleur is a straightforward but precise maintenance task that significantly improves shifting performance. By following the correct procedure—removing the old cable, installing the new one, adjusting tension, and fine-tuning limit screws—you ensure smooth and reliable front shifting. Regular attention to cable condition and derailleur adjustment will keep your drivetrain performing at its best, extending the life of both the derailleur and the entire groupset.

The Shimano FD-5700 [paid link] front derailleur from the 105 10-speed groupset is a reliable component when set up correctly. However, precise adjustment of the limit screws is essential to ensure smooth, accurate shifting and to prevent chain drop. Riders often overlook this step or misadjust the screws, which can compromise performance and lead to premature wear on the drivetrain. This guide will explain how the limit screws work, how to adjust them properly, and what to look for when fine-tuning your FD-5700 [paid link] front derailleur.

Understanding the Limit Screws on the FD-5700

The FD-5700 [paid link] derailleur has two limit screws, marked with an “L” and an “H.” These screws control the range of motion of the front derailleur cage.

  • The L screw (Low limit): Sets the inward travel of the cage, determining how far it moves toward the small chainring. Proper adjustment prevents the chain from dropping inside the crank.
  • The H screw (High limit): Sets the outward travel of the cage, determining how far it moves toward the large chainring. Correct adjustment ensures the chain shifts up cleanly without overshooting and dropping off the outside of the chainring.

When properly adjusted, these screws keep the derailleur aligned with the chainrings, ensuring reliable shifts without rubbing or derailment.

Tools Required

  • 2 mm or 2.5 mm hex key (for cable anchor bolt, if readjustment is needed)
  • Phillips screwdriver (for limit screws)
  • Bike stand [paid link] or method to elevate the drivetrain for free pedaling
  • Chain lube (optional, for smooth testing)

Preparing for Adjustment

Before touching the limit screws, it is essential to check that the derailleur is mounted correctly. The outer cage plate should sit parallel to the chainrings, and the bottom edge of the cage should clear the largest chainring by 1–3 mm. If the derailleur is misaligned, no amount of screw adjustment will deliver proper performance.

Cable tension should also be set properly before fine-tuning. If the cable is slack or overtightened, the derailleur will not move consistently within the limits you set.

Setting the Low Limit Screw (L)

  1. Shift the chain to the small chainring in the front and the largest cog in the rear. This position provides maximum inward chainline stress.
  2. Pedal the bike while observing the cage’s inner plate relative to the chain.
  3. Use the Phillips screwdriver to adjust the L screw. Turning the screw clockwise moves the cage outward, reducing inward travel. Turning it counterclockwise allows the cage to move further inward.
  4. The ideal setting is a clearance of 0.5–1 mm between the inner cage plate and the chain. This prevents rubbing while ensuring the derailleur does not push the chain off the inside of the chainring.

Setting the High Limit Screw (H)

  1. Shift the chain to the large chainring in the front and the smallest cog in the rear. This creates maximum outward chainline stress.
  2. While pedaling, observe the outer cage plate relative to the chain.
  3. Use the Phillips screwdriver to adjust the H screw. Turning the screw clockwise limits outward travel, preventing overshift. Turning it counterclockwise allows more outward motion.
  4. The correct adjustment leaves a 0.5–1 mm clearance between the outer cage plate and the chain, ensuring no rubbing while preventing the chain from overshooting the large ring.

Fine-Tuning for Smooth Shifting

After both screws are adjusted, shift repeatedly through the full gear range to check for any issues. If the chain hesitates or rubs in certain combinations, recheck the alignment of the derailleur and make small corrections to cable tension. The FD-5700 relies on precise balance between limit screw settings and cable pull, so patience during setup pays off in long-term performance.

A common mistake is over-tightening the limit screws. Doing so restricts derailleur movement too much, leading to missed shifts or excessive chain rub. Always make small, incremental adjustments and re-test under pedaling load.

Troubleshooting Common Limit Screw Issues

  • Chain drops inside: The L screw is too loose, allowing excessive inward movement. Tighten gradually until the cage stops the chain at the small ring.
  • Chain overshoots large chainring: The H screw is too loose, letting the cage move too far outward. Tighten carefully until shifting stops at the correct point.
  • Persistent rubbing in big/big or small/small combinations: Verify derailleur alignment and cable tension. The FD-5700 is designed for cross-chaining tolerance, but improper setup can cause rub.
  • Slow shifting up or down: Check cable tension before altering the limit screws. Many shifting delays come from a stretched cable, not screw adjustment.

Optimizing FD-5700 Limit Screw Adjustment

When set correctly, the FD-5700 front derailleur delivers crisp shifts even under moderate pedaling force. Riders seeking maximum performance should recheck the limit screws after the first few rides following installation. Cables can settle, causing small changes that affect shifting precision.

Regular inspection is also recommended during routine drivetrain maintenance. Cleaning and lubricating the derailleur pivot points can reduce friction and maintain accurate cage movement, keeping the limit screw settings consistent over time.

Conclusion

Limit screw adjustment is one of the most critical steps in setting up the Shimano FD-5700 front derailleur. By carefully balancing the low and high screw positions, riders can eliminate chain drop, overshift, and rubbing issues. With correct setup, the FD-5700 provides smooth and reliable front shifting, enhancing overall drivetrain performance and extending component life.

The Shimano FD-5700 [paid link] front derailleur, part of the 105 groupset, is known for delivering precise shifting when installed and maintained correctly. However, like all mechanical components, it can suffer from common issues that affect performance. Understanding these problems and their solutions ensures smooth front shifting, longer component life, and consistent ride quality.

Improper Cable Tension

One of the most frequent issues with the FD-5700 [paid link] front derailleur is incorrect cable tension. Too little tension results in delayed or incomplete shifts to the large chainring, while too much tension can cause overshifting. Correct tension is essential for accurate shifting across the chainrings. To fix this, check the barrel adjuster on the downtube or inline adjuster, and make small turns until shifts are crisp and reliable. Riders should always verify final adjustments under pedaling load to ensure accuracy.

Misaligned Derailleur Cage

Another common problem is cage misalignment relative to the chainrings. If the derailleur is mounted too high, shifting becomes sluggish, and the chain may drop. If it is rotated at the wrong angle, the cage can rub the chain in several gears. For the FD-5700 [paid link], Shimano specifies that the outer cage plate should be parallel to the large chainring, with 1–3 mm clearance above the tallest teeth. Rechecking this alignment during installation prevents most shifting inconsistencies.

Chain Rub in Cross Gearing

Chain rub occurs frequently on the FD-5700, especially when cross-chaining. While some rub is expected in extreme gear combinations, excessive noise usually points to an incorrect limit screw setting or misadjusted trim position. The solution is to fine-tune the front derailleur’s inward and outward limit screws so the cage provides just enough clearance without allowing the chain to overshoot. Riders should also use the trim feature properly to minimize noise in certain gear ratios.

Sticky or Frayed Shift Cables

A sluggish or unresponsive FD-5700 derailleur often stems from cable friction or wear. Cables routed through old housing can stick, and frayed cable ends can catch at the derailleur pinch bolt. This results in inconsistent shifts or the inability to reach the large chainring. Replacing worn cables and housing restores crisp shifting and prevents future failures. Lubricating the cable during installation also improves long-term performance.

Incorrect Limit Screw Adjustment

Limit screw misadjustment is a major cause of chain drop on the FD-5700 front derailleur. If the low limit screw is too loose, the chain may fall off the small ring into the bottom bracket. If the high limit screw is not properly set, overshifting off the large ring is possible. Each limit screw must be precisely tuned: the low screw restricts inward movement, while the high screw restricts outward movement. Correct adjustment ensures the chain stays secure on both rings under load.

Excessive Dirt and Contamination

The FD-5700 relies on smooth pivot movement for accurate shifting. Dirt, old grease, and road grime can build up inside the pivots, causing sluggish response. Regular cleaning with a degreaser and light lubrication of the pivot points keeps the derailleur moving freely. Neglecting this maintenance often leads to poor shift quality and premature wear of the mechanism.

Chain and Chainring Wear

Sometimes shifting issues are incorrectly blamed on the FD-5700 itself, when the real culprit is worn drivetrain components. A stretched chain or worn chainring teeth make it difficult for the derailleur to guide the chain smoothly. If new adjustments do not solve poor shifting, inspecting the chain and chainrings is essential. Replacing these worn parts often restores shifting precision immediately.

Compatibility Problems

The FD-5700 is designed for 10-speed Shimano drivetrains and works best with matching shifters, chainrings, and chains. Using it with non-compatible components, such as 11-speed parts or different chainring profiles, can cause poor alignment and unreliable shifts. Riders should always confirm drivetrain compatibility when mixing parts to avoid unnecessary performance issues.

Loose Clamp Bolt or Mounting Issues

A less obvious but critical issue is a loose clamp bolt or improper mounting on the seat tube. If the derailleur body shifts under load, all other adjustments become ineffective. Checking torque on the clamp bolt and ensuring the derailleur is seated correctly prevents unwanted movement and maintains consistent shifting.

Conclusion

The Shimano FD-5700 front derailleur delivers excellent shifting when installed, adjusted, and maintained correctly. Most problems—such as poor cable tension, misaligned cages, limit screw errors, and contamination—can be solved with straightforward adjustments and regular upkeep. By understanding these common issues and applying precise fixes, riders can keep their FD-5700 operating smoothly for years of reliable performance.

The Shimano FD-5700 [paid link] front derailleur, part of the 105 5700 groupset, is known for reliable shifting when installed and adjusted correctly. However, many riders encounter noisy shifting, which often signals an issue with alignment, cable tension, or wear. Understanding how to identify the root cause and correct it is essential for maintaining smooth and quiet drivetrain performance. This guide explains how to diagnose and fix noisy shifting specifically on the Shimano FD-5700 [paid link] front derailleur.

Tools Required

  • 5 mm hex key
  • Phillips screwdriver
  • Torque wrench [paid link] with hex bit set
  • Cable cutters
  • Chain checker tool
  • Bike stand [paid link] (recommended)

Understanding Common Sources of Noise

Noisy shifting on the Shimano FD-5700 [paid link] typically originates from three key areas: derailleur alignment, cable tension, and drivetrain wear. The cage may rub against the chain if not positioned correctly, while improper cable tension can cause hesitation or noise during shifts. Additionally, worn chains, chainrings, or cables increase friction and vibration, leading to excess drivetrain noise. Identifying the exact source ensures efficient repairs without unnecessary adjustments.

Checking Derailleur Alignment

Correct positioning of the FD-5700 front derailleur is crucial. The outer cage plate should be parallel to the large chainring, and the clearance between the cage and chainring should be approximately 1–3 mm. If the derailleur sits too high or is angled, the chain will rub during shifts, especially in extreme gear combinations. Repositioning requires loosening the derailleur clamp bolt, aligning the cage precisely, and re-tightening to Shimano’s recommended torque settings.

Inspecting Limit Screw Adjustment

The FD-5700 features both low and high limit screws, which control the derailleur’s movement range. An incorrectly set low limit can cause rubbing in the small chainring, while an overly tight high limit may lead to chain contact on the large chainring. Using a Phillips screwdriver, check that the cage clears the chain without excessive lateral movement. Fine-tuning these screws eliminates unnecessary chain rub that often produces unwanted noise.

Evaluating Cable Tension

Cable tension directly impacts the precision and quietness of front shifting. Too little tension causes slow or incomplete shifts, while too much creates resistance and noise. On the FD-5700, micro-adjustments can be made via the barrel adjuster located near the shifter or inline adjuster if installed. Shift between chainrings while applying slight tension adjustments until the derailleur operates smoothly and quietly across all positions.

Inspecting the Chain and Chainrings

Worn drivetrain components contribute significantly to noisy shifting. A stretched chain can skip or chatter when engaged with chainrings, while worn teeth create poor engagement angles. Use a chain checker tool to measure wear, replacing the chain if elongation exceeds 0.75%. Examine chainring teeth for shark-fin shaping or burrs, as these defects lead to constant chain contact and vibration during pedaling. Replacing worn parts restores optimal compatibility with the FD-5700.

Checking Cable and Housing Condition

Cables and housing degrade over time, often causing drag that results in noise during shifting. Frayed or corroded inner cables, combined with contaminated housing, restrict free movement of the derailleur. Inspect the full cable path, replacing damaged or rusted sections. Installing a fresh, lubricated cable set greatly improves shifting performance and eliminates unnecessary friction-related noise.

Fine-Tuning Under Load

After adjustments, test shifting while pedaling under moderate load in a bike stand [paid link] or during a short ride. Noise often appears in specific gear combinations, such as small chainring to small cog, due to cross-chaining. Verify that the derailleur cage clears the chain in practical riding conditions, making incremental barrel adjustments as necessary. The FD-5700 allows for trim adjustments at the shifter, which should be used to minimize rub in borderline gear combinations.

Preventive Maintenance for Noise-Free Performance

Keeping the FD-5700 front derailleur running quietly requires routine inspection and maintenance. Regular cleaning of the derailleur cage prevents buildup of dirt that can cause rubbing. Lubricating pivot points ensures smooth mechanical movement, reducing creaks and grinding. Checking cable tension monthly and inspecting for component wear extends the life of the drivetrain while preventing noisy operation. Consistent care ensures reliable and quiet shifting for thousands of kilometers.

Conclusion

Noisy shifting on the Shimano FD-5700 front derailleur is usually the result of alignment issues, cable tension imbalance, or drivetrain wear. By systematically checking derailleur position, limit screw adjustment, cable condition, and chain wear, riders can quickly eliminate unwanted noise. Once properly tuned, the FD-5700 delivers smooth and quiet front shifting that enhances overall riding performance.

The Shimano FD-5700 [paid link] front derailleur is part of the 105 groupset, designed for precise shifting performance on double chainring road drivetrains. Like all front derailleurs, it requires consistent maintenance to operate smoothly and avoid issues such as chain rub, sluggish shifts, or premature wear. Developing a structured maintenance plan is the key to keeping your FD-5700 [paid link] working at peak efficiency for years.

Understanding the FD-5700 Front Derailleur

The FD-5700 [paid link] is a braze-on or clamp-on style front derailleur built for 10-speed drivetrains. It is optimized for road bikes with compact or standard double cranksets. Shimano engineered it for light shifting effort, stable performance, and long-term durability when paired with compatible 105 shifters and chains. However, even with this durability, the derailleur must be regularly cleaned, adjusted, and lubricated.

Tools Required

  • 5 mm hex key
  • Phillips screwdriver
  • Cable cutters
  • Torque wrench [paid link]
  • Degreaser
  • Chain lubricant
  • Clean rags

Routine Cleaning

The FD-5700 sits in a high-debris zone near the chainrings, meaning it accumulates grime quickly. Regular cleaning prevents dirt buildup that can slow down shifting.

Start by applying a degreaser to the derailleur cage, pivots, and clamp area. Use a clean rag to wipe away grease, dirt, and chain oil. Avoid spraying directly into pivot points, as harsh degreasers may strip essential factory lubrication. Once the derailleur is clean, lightly lubricate the pivots with a drop of high-quality oil. This ensures smooth cage movement without attracting excess dirt.

For riders in wet or muddy conditions, cleaning should be performed weekly. For dry road riding, monthly cleaning is usually sufficient.

Inspecting the Cable and Housing

Cables and housing are critical to derailleur performance. The FD-5700 relies on smooth cable movement for precise shifts. Over time, cables stretch, fray, or corrode, and housing can develop friction points.

During each cleaning session, inspect the cable where it clamps to the derailleur. Look for signs of rust, fraying, or compression in the housing. If shifting feels heavy or imprecise, replacing the cable and housing will restore responsiveness. A fresh, stainless-steel cable paired with low-friction housing is the best option for long-term reliability.

Limit Screw Maintenance

The FD-5700 uses two limit screws—marked “L” and “H”—to set the derailleur cage travel. These prevent the chain from overshooting the chainrings.

Over time, vibration and use may cause the screws to drift slightly. As part of your maintenance plan, verify limit screw positions during every tune-up. The low-limit screw should keep the chain secure on the small ring without rubbing, while the high-limit screw should prevent overshifts into the crank arm when shifting to the large ring. A quarter-turn adjustment is often all that’s needed to correct small deviations.

Cable Tension Checks

Even a perfectly aligned derailleur won’t perform well if cable tension is off. As cables stretch, shifts to the big ring may become sluggish or incomplete.

To maintain correct tension, check the alignment of the cage relative to the chain. If the chain hesitates moving onto the large chainring, increase tension slightly using the barrel adjuster on the shifter. If the chain overshoots or rubs excessively, decrease tension. Performing this check monthly ensures reliable shifting and reduces long-term wear on both chain and chainrings.

Cage Alignment Verification

A misaligned derailleur cage is one of the most common causes of poor shifting. The FD-5700 cage should sit parallel to the chainrings, with a clearance of 1–3 mm above the largest chainring teeth.

At least twice per season, verify cage alignment. If the derailleur has been knocked out of place due to transport or a minor crash, loosen the mounting bolt with a 5 mm hex key, realign, and retighten to the recommended torque (5–7 Nm). Keeping the cage in the correct position prevents chain rub and reduces drivetrain friction.

Lubrication Plan

Lubrication is vital to derailleur longevity. The FD-5700 has several pivot points that must move freely for precise shifts. Apply a single drop of lightweight oil to each pivot after cleaning. Avoid over-lubricating, as excess oil attracts dirt and accelerates wear.

It’s best to check pivot lubrication every two weeks during high-mileage riding seasons and once a month during light use periods.

Seasonal Overhaul

In addition to routine cleaning and inspection, the FD-5700 benefits from a seasonal overhaul. This includes removing the derailleur from the frame, deep cleaning the cage and pivots, and inspecting the clamp or braze-on mount for corrosion. Reinstall the derailleur with fresh grease on the bolt threads and correct torque. At this stage, also replace the cable and housing if they show any sign of wear.

Performing a seasonal overhaul, especially before a long riding season, ensures the derailleur continues to deliver precise shifting without unexpected failures.

Troubleshooting During Maintenance

While carrying out routine maintenance, you may notice early signs of problems. Common issues include:

  • Chain rub in certain gears – Often caused by cable stretch or cage misalignment.
  • Sluggish upshifts to the large ring – Typically due to low cable tension or contamination in housing.
  • Overshifting past the large ring – Usually a result of an incorrectly set high-limit screw.
  • Inconsistent shifting under load – May indicate cable fray or derailleur pivots needing lubrication.

Addressing these issues early prevents more serious drivetrain problems and keeps riding smooth.

Extending the Lifespan of the FD-5700

With proper care, the FD-5700 can last for many seasons. The key lies in consistent maintenance rather than waiting for problems to appear. Regular cleaning, correct lubrication, and proactive cable replacement ensure smooth performance. Riders who follow a structured plan often see their front derailleurs outlast multiple chains and cassettes, proving the importance of preventive care.

Conclusion

The Shimano FD-5700 front derailleur is a reliable and precise component when maintained correctly. A structured plan of cleaning, lubrication, cable checks, and seasonal overhauls keeps it running like new for years. Small, regular adjustments prevent major problems, while proactive inspections extend its lifespan. By following this maintenance plan, riders ensure their FD-5700 delivers the crisp, accurate shifting expected from Shimano’s 105 series.

The Shimano FD-5700 [paid link] front derailleur, part of the 105 10-speed groupset, is designed to deliver smooth and precise front shifting. However, if your set-up feels sluggish, noisy, or inconsistent, the issue often lies not in the derailleur itself but in the installation and adjustment process. This guide covers why the FD-5700 [paid link] front derailleur may feel off, how to identify the root cause, and how to correct it for optimal shifting performance.

Tools Required

  • 5 mm hex key
  • Torque wrench [paid link] with hex bit
  • Phillips screwdriver
  • Cable cutters
  • Bike stand [paid link] (recommended)

Understanding the FD-5700 Front Derailleur Design

The FD-5700 [paid link] is a braze-on or clamp-style front derailleur designed for Shimano’s 10-speed road drivetrains. It is optimized for a double chainring system and requires precise positioning to function correctly. Unlike newer generations, the FD-5700 relies heavily on exact cable tension and correct limit screw adjustment. Any deviation in alignment or tension will quickly result in poor performance, chain rub, or incomplete shifts.

Common Reasons Why the FD-5700 Feels Off

Several issues can cause poor set-up quality with the FD-5700:

Incorrect Mounting Height

If the derailleur cage sits too high above the big chainring, shifts will feel slow and may not complete. Conversely, if it is too low, the cage can catch on the teeth of the chainring.

Poor Cage Alignment

The outer cage plate must run parallel to the chainrings. Even a slight toe-in or toe-out misalignment can create excessive chain rub and inconsistent shifting.

Improper Cable Tension

Low cable tension leads to the derailleur failing to shift up to the big ring, while too much tension can make it difficult to return to the small ring.

Limit Screw Errors

Incorrect high- or low-limit screw settings can prevent the derailleur from reaching the chainrings or allow the chain to drop.

Worn or Contaminated Components

Old cables, corroded housing, or worn chainrings can degrade performance, even if the derailleur itself is correctly installed.

Step-by-Step Fix for FD-5700 Set-Up Issues

Step 1: Check Mounting Position

Ensure the derailleur cage sits 1–3 mm above the tallest tooth on the big chainring. Adjust the clamp or braze-on mount position if necessary.

Step 2: Align the Cage

Rotate the derailleur so that the outer plate runs exactly parallel to the chainrings. This eliminates side-loading that causes rubbing.

Step 3: Reset Limit Screws

Back out both limit screws and reset them:

  • Low-limit screw should position the cage just clear of the chain when in the small ring and largest sprocket.
  • High-limit screw should prevent the chain from overshifting when moving to the big ring.

Step 4: Correct Cable Tension

Pull the cable taut and secure it with the anchor bolt using a torque wrench [paid link]. Fine-tune the tension using the barrel adjuster until the derailleur moves cleanly across both chainrings without hesitation.

Step 5: Test Under Load

Shift repeatedly under moderate pedaling force. Check for smooth movement, absence of chain rub, and complete transitions between chainrings. Make small adjustments to the barrel or limit screws as needed.

Advanced Optimization for Better Shifting

To improve long-term performance of the FD-5700, consider the following refinements:

  • Use low-friction cable housing: This reduces resistance and makes shifting feel lighter.
  • Upgrade to stainless steel or polymer-coated cables: These improve durability and maintain tension longer.
  • Match with Shimano 10-speed compatible chainrings and shifters: Mixing components from different generations often results in poor alignment and inconsistent shifting.
  • Regular cleaning and lubrication: Prevents dirt build-up, which can restrict derailleur movement.

Compatibility Considerations

The Shimano FD-5700 front derailleur is designed specifically for 10-speed Shimano road drivetrains. It is compatible with Shimano 105, Ultegra, and Dura-Ace 10-speed systems. However, it is not optimized for 11-speed drivetrains due to differences in chainline and pull ratios. Using the FD-5700 with mismatched components will compromise shifting quality.

Conclusion

When the Shimano FD-5700 front derailleur feels off, the problem usually lies in the set-up rather than the component itself. Correct mounting height, cage alignment, limit screw adjustment, and proper cable tension are critical for smooth, consistent performance. By following a systematic adjustment process and maintaining the derailleur with clean, lubricated components, you can restore crisp and reliable front shifting that the FD-5700 was designed to deliver.
