The Shimano FD-5700 [paid link] front derailleur, part of the 105 5700 series, is a reliable and performance-driven component designed for precise and smooth front shifting. Like all mechanical parts, it requires proper installation, routine adjustment, and ongoing care to deliver consistent performance. This guide will cover the best practices to maximize the longevity and efficiency of the FD-5700 [paid link], ensuring your shifting remains crisp and reliable ride after ride.
Tools Required
- 5 mm hex key
- Torque wrench [paid link] with Nm scale
- Phillips screwdriver
- Cable cutters
- Chain wear checker
- Cleaning brush and degreaser
- Light lubricant
Correct Installation of the FD-5700 Front Derailleur
Proper installation is the foundation of smooth shifting. The FD-5700 [paid link] is a braze-on style derailleur, though clamp adapters are available for frames without a braze-on mount. The derailleur cage should sit parallel to the chainrings, and its outer plate should clear the large chainring teeth by 1–3 mm. Setting this gap correctly prevents chain rub and ensures the derailleur can move the chain efficiently between rings.
The fixing bolt should be torqued to Shimano’s recommended 5–7 Nm. Overtightening risks frame damage, while undertightening can cause derailleur slippage under load. Ensuring correct alignment at this stage reduces the need for frequent readjustments later.
Cable Tension and Limit Screw Adjustment
The FD-5700 relies on correct cable tension for smooth operation. After routing the cable through the anchor bolt, apply tension by hand and tighten to 5–7 Nm. Use the barrel adjuster on the downtube or inline adjuster to fine-tune tension during setup and after initial cable stretch.
Limit screws are essential for preventing over-shifting. The low-limit screw should position the derailleur so that, in the small chainring and largest rear cog, the chain clears the inner cage plate by a fraction of a millimeter. The high-limit screw ensures that in the large chainring and smallest rear cog, the chain runs close to but not against the outer plate. This precise adjustment prevents chain drop and unnecessary rubbing.
Regular Cleaning and Lubrication
Keeping the FD-5700 clean is critical for maintaining crisp shifting. Dirt, grime, and chain lube buildup inside the derailleur cage and pivot points lead to sluggish movement. Routine cleaning with a degreaser and a soft brush keeps the mechanism moving freely. After cleaning, apply a drop of light lubricant to the pivot joints, wiping away any excess to avoid attracting debris.
The derailleur cage should also be inspected for wear from repeated chain contact. Any rough edges or sharp burrs can compromise chain movement and accelerate drivetrain wear.
Cable and Housing Maintenance
The FD-5700 is sensitive to cable friction. Old, corroded, or contaminated cables can cause heavy shifting or missed shifts. Replacing the cable and housing at least once per season, or more often in wet riding environments, keeps performance consistent. Always use high-quality stainless steel cables and lined housing for reduced friction. Properly pre-stretched cables help avoid the need for constant readjustment.
Troubleshooting Common Performance Issues
If shifting feels slow or inconsistent, the most common causes are improper cable tension, misaligned derailleur position, or contaminated cables. Noisy shifting on the big chainring often indicates the high-limit screw needs fine-tuning. Chain rub in cross-chain positions is normal, but excessive noise in moderate gear combinations points to derailleur alignment issues.
If problems persist even after adjustment, inspect the chain and chainrings for wear. The FD-5700 performs best when paired with components in good condition, as worn teeth or stretched chains can make even the best adjustments ineffective.
Optimizing Performance Through Customization
The FD-5700 is designed for use with Shimano’s 10-speed systems. To optimize performance, pair it with Shimano 5700-series STI shifters and matching chainrings. While cross-compatibility with some other Shimano groups is possible, staying within the series ensures the best shifting quality. Riders seeking a lighter feel at the lever can use polymer-coated cables to reduce friction further.
Chainline also plays a role in front shifting quality. Ensuring the bottom bracket and crankset are installed to specification helps maintain the derailleur’s optimal operating position.
Comparison with Similar Models
Compared with the previous FD-5600, the FD-5700 features a refined cage profile designed to better handle wider-range compact cranksets. This improvement allows smoother shifts with less trimming required. While newer models such as the 5800 (11-speed) bring additional enhancements, the FD-5700 remains a robust and reliable option for 10-speed riders who prioritize consistent performance without upgrading the entire drivetrain.
Maintenance Schedule for Long-Term Reliability
To keep the FD-5700 running like new, adopt a structured maintenance routine. Clean and lubricate the derailleur monthly, or more often in adverse weather. Inspect cable tension every few rides and adjust as needed. Replace cables and housing at least annually, and check for cage wear and pivot looseness during major tune-ups. Following this routine ensures your derailleur continues to deliver precise shifts over many seasons.
Conclusion
The Shimano FD-5700 front derailleur is a dependable component that, when installed and maintained correctly, provides smooth and accurate front shifting. By focusing on correct setup, regular cleaning, proper lubrication, and timely cable replacement, cyclists can maximize the performance and lifespan of this derailleur. With consistent care, the FD-5700 remains a high-performing part of any 10-speed Shimano road drivetrain, offering riders confidence in every shift.
