Step-by-Step Shimano FD-4700 Maintenance Routine
1. Wipe Down and Inspect the Derailleur
Regularly cleaning the derailleur will prevent dirt and grime from affecting shifting performance.
- Shift to the smallest chainring to expose the derailleur’s inner plates.
- Use a lint-free cloth to wipe off dirt and grease.
- Check for any signs of rust or corrosion on the derailleur and shifting cable.

2. Clean and Lubricate the Pivots for Smooth Shifting
Dirt buildup in the derailleur pivots can cause sluggish shifting and increased friction.
- Apply a small drop of lubricant to each pivot point.
- Shift through the gears to distribute the lubricant evenly.
- Wipe off any excess lubricant to prevent dirt accumulation.
Avoid applying lubrication to the derailleur plates, as this can cause the chain to slip.
3. Check and Adjust Cable Tension
Cable tension is essential for precise shifting. Over time, cables stretch, causing slow or inconsistent shifts.
- Shift to the smallest chainring and check if the derailleur moves smoothly.
- Turn the barrel adjuster to fine-tune cable tension.
- Turn counterclockwise to increase tension if shifting is slow.
- Turn clockwise to reduce tension if shifting is too abrupt.
If the cable is frayed or corroded, replace it with a new one.

4. Adjust the Limit Screws to Prevent Chain Rub
Incorrect limit screw settings can cause chain rub, shifting delays, or dropped chains.
- Shift to the smallest chainring and adjust the low limit screw until the chain is 0–0.5 mm from the inner derailleur plate.
- Shift to the largest chainring and adjust the high limit screw until the chain is 0–0.5 mm from the outer derailleur plate.

5. Inspect the Derailleur for Wear and Misalignment
A misaligned derailleur can cause poor shifting performance.
- Check that the derailleur cage is parallel to the chainrings.
- Ensure that the derailleur is positioned 1–3 mm above the largest chainring.
- If shifting feels stiff or slow, check for dirt buildup in the derailleur pivots.
