The Shimano FD-5700 [paid link] front derailleur, part of the popular 105 5700 series, is a precision component that ensures smooth and accurate front shifting. Like all mechanical parts, it requires regular maintenance to deliver peak performance and long lifespan. Dirt, moisture, and improper lubrication can quickly degrade its efficiency, leading to sluggish shifting or premature wear. A structured cleaning and lubrication routine is essential to keep your FD-5700 [paid link] running flawlessly.
Understanding the FD-5700 Front Derailleur
The Shimano FD-5700 [paid link] is a braze-on or clamp-style front derailleur designed for 10-speed drivetrains. It features a wide inner link for stiffness and consistent shifting under load. The derailleur operates with a mechanical cable pull, making correct lubrication critical to minimize friction at the pivot points. Unlike electronic systems, mechanical derailleurs are more susceptible to contamination, and neglecting them can result in compromised shifting precision.
Tools Required
- Degreaser (bike-specific, non-corrosive)
- Clean rags or microfiber cloths
- Small nylon brush or old toothbrush
- Light chain lubricant or PTFE-based oil
- Isopropyl alcohol (for final cleaning)
- Torque wrench [paid link] (if reinstalling the derailleur after deep cleaning)
Cleaning the FD-5700 Front Derailleur
A clean derailleur is the foundation of precise front shifting. Contamination buildup increases resistance at the pivots and cage plates, which eventually causes chain rub and hesitation during gear changes.
Begin by removing surface dirt with a damp rag. For deeper cleaning, apply a degreaser to the pivot joints and cage area. Use a nylon brush or an old toothbrush to scrub away grime and dried lubricant. Pay special attention to the inner and outer cage plates, as these are in direct contact with the chain and prone to grease accumulation.
After scrubbing, rinse the component with a small amount of water or wipe it down using a rag dampened with isopropyl alcohol. Ensure the derailleur is completely dry before applying fresh lubrication.
Lubricating the FD-5700 Front Derailleur
Lubrication plays a vital role in keeping the FD-5700 smooth and responsive. Apply a small drop of light chain lubricant or PTFE-based oil to each pivot point. Shimano designed this derailleur with multiple moving joints, and all must move freely for consistent performance.
Work the derailleur back and forth by hand to allow the lubricant to penetrate the pivots. Wipe away any excess oil with a clean rag, as surplus lubrication can attract dirt. The derailleur cage itself does not require heavy lubrication, but a very light wipe of oil on the inner surfaces can reduce friction where the chain passes during shifts.
Preventing Premature Wear
Consistent care is key to extending the life of the FD-5700. Avoid over-lubrication, as too much oil creates sticky buildup that traps dirt. Likewise, avoid harsh degreasers that may strip essential coatings or seep into bushings. A monthly cleaning and lubrication routine is sufficient for most riders, but wet or dusty riding conditions may require more frequent attention.
In addition to routine maintenance, ensure that the derailleur cable and housing are kept clean and properly lubricated. Cable friction often mimics derailleur problems, and keeping both systems in top condition ensures reliable shifting.
Optimizing Performance Through Maintenance
Regular lubrication and cleaning do more than prolong the derailleur’s life; they also improve ride quality. Smooth pivot action reduces the amount of force needed at the shift lever, which leads to crisper gear changes. Proper care also prevents unnecessary noise from chain rub, making the drivetrain quieter and more efficient. Riders who invest in maintaining their FD-5700 notice fewer issues with alignment, limit screw drift, and cable tension.
Conclusion
The Shimano FD-5700 front derailleur is a durable and precise component when maintained correctly. A consistent cleaning and lubrication routine ensures it delivers accurate shifting for years. By focusing on pivot lubrication, cage cleaning, and preventing contamination, cyclists can maximize both performance and longevity. Treat the FD-5700 with care, and it will continue to deliver the crisp shifting Shimano 105 is known for.
