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.
