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.
