Learn how to adjust the derailleur for proper, smooth shifting of your gears up and down the cassette
-
Limit Screw Check:
- Ensure the high and low limit screws are appropriately set before adjusting indexing.
- Check the video on limit screws for guidance if needed.
-
Initial Check:
- Begin with the chain in the lowest cog (highest gear).
- Ensure the shifter cable is loose enough for the derailleur/chain to reach the smallest cog.
- While pedaling, use the shifter to shift up the cassette one gear at a time, observing if the chain smoothly moves to the next cog.
-
Adjustment Process:
- If the chain doesn't smoothly shift up into the next cog or will not shift up into the next cog, you need more tension on the cable.
- Locate the barrel adjuster on the shifter and give it a quarter to a half turn counterclockwise to add tension.
- Shift again and repeat process until the chain smoothly moves to the next cog with ease.
- Remember to shift back down into the smallest cog before making further adjustments to the barrel adjuster if necessary.
-
Fine-Tuning:
- After reducing noise, add an extra half turn of tension and listen for any noise.
- If noise is minimal, gradually add tension until noise is heard, then back off a quarter turn.
- Shift one gear at a time, listening for noise and adjusting tension as needed.
-
Indexing Through the Cassette:
- Index through all gears, starting from the lowest, checking for smooth and quiet shifts.
- If there's hesitation or noise, adjust tension using the barrel adjuster.
- Ensure smooth indexing from the lowest to the highest gear and vice versa.
-
Final Adjustment:
- Fine-tune tension to minimize noise while maintaining smooth indexing.
- The goal is to have the derailleur smoothly jump up and down the cogs with minimal noise.
By following these steps, you can effectively adjust the rear derailleur indexing on your e-bike for a quieter and smoother riding experience.
