The Shimano FD-6700 [paid link] Ultegra front derailleur is a precise component designed to deliver smooth and accurate shifts. However, to maintain its performance over time, it requires consistent cleaning and lubrication. Dirt, road grime, and moisture can quickly compromise shifting accuracy if not addressed properly. This guide explains the best lubrication and cleaning routine specifically for the FD-6700 [paid link], ensuring reliability and longevity.
Understanding the Shimano FD-6700 Front Derailleur
The FD-6700 [paid link] is a braze-on style front derailleur designed for 10-speed drivetrains. Its lightweight aluminum construction and wide link design provide stiffness for better shifting. Unlike older models, the FD-6700 demands precise set-up and ongoing maintenance to keep shifts crisp. Because its pivots and linkage points are exposed, they are vulnerable to contamination, making proper cleaning and lubrication essential.
Tools Required
- Mild bike-specific degreaser
- Clean microfiber cloths
- Soft-bristle brush or old toothbrush
- Light synthetic lubricant (drip bottle, not spray)
- Isopropyl alcohol (optional for final wipe-down)
Step 1: Preparing the FD-6700 for Cleaning
Before cleaning, shift the derailleur to the small chainring position to reduce cable tension. This position exposes more of the derailleur cage and linkage, making it easier to access the key areas. If the bike is heavily contaminated with dirt, rinse gently with water first to prevent scratching during cleaning.
Step 2: Removing Dirt and Grime
The derailleur’s pivots and inner cage plates are prone to dirt buildup from chain lubricant. Apply a small amount of bike-specific degreaser to the cage plates and pivot areas. Use a soft brush to work the degreaser into crevices without forcing contaminants deeper inside. Wipe thoroughly with a microfiber cloth until the surfaces are free of residue. Avoid soaking the derailleur, as this can wash out factory-applied grease in the pivots.
Step 3: Drying the Derailleur
Once cleaned, allow the derailleur to dry fully before applying lubrication. Use a dry microfiber cloth to remove moisture from the linkage and cage. For faster drying, you may use isopropyl alcohol on a cloth, which evaporates quickly and leaves the surface clean.
Step 4: Lubricating the FD-6700 Pivots
The FD-6700 has several key pivot points that must move freely for accurate shifting. Apply one drop of light synthetic lubricant directly onto each pivot. Work the derailleur back and forth by hand to distribute the lubricant evenly. Wipe away any excess to prevent attracting new dirt. Do not apply grease or heavy oils, as these will stiffen the pivots and collect grime.
Step 5: Lubricating the Cage Contact Areas
The inner and outer cage plates can develop noise where the chain makes contact. To minimize friction, apply a thin film of lubricant to the inside of the derailleur cage. This should be done sparingly, as too much lubricant here can transfer onto the chain and cause contamination. After applying, wipe down the surfaces so only a trace remains.
Step 6: Avoiding Common Mistakes
Many riders make the mistake of over-lubricating their FD-6700, leading to sticky pivots and poor shifting. Another common error is using aerosol sprays, which can spread lubricant uncontrollably and contaminate braking surfaces. Always apply lubricant with precision and wipe away the excess immediately.
Recommended Cleaning Frequency
For most riders, cleaning and lubricating the FD-6700 every two to three weeks is sufficient. However, if you frequently ride in wet or dusty conditions, maintenance should be performed weekly. After a rainy ride, clean and lubricate the derailleur as soon as possible to prevent rust from forming on the pivots.
Long-Term Performance Benefits
Following this routine ensures the Shimano FD-6700 continues to shift with accuracy. Clean pivots reduce cable drag, while proper lubrication keeps the linkage operating smoothly. In the long term, this routine extends the lifespan of the derailleur, delays wear, and minimizes the need for replacement parts.
Conclusion
The Shimano FD-6700 front derailleur is a high-performance component that requires careful maintenance to deliver consistent results. A regular routine of cleaning dirt buildup, drying thoroughly, and applying light lubrication to pivots and cage surfaces ensures optimal performance. By avoiding over-lubrication and focusing on precision, riders can keep their FD-6700 shifting as smoothly as the day it was installed.
