Adjusting the Shimano RD-R2000 for Perfect Shifting
Setting the High Limit Screw (H-Screw)
The H-screw prevents the derailleur from shifting past the smallest cog.
- Shift to the smallest rear cog.
- Turn the H-screw clockwise to move the jockey wheel closer to the cog.
- Turn counterclockwise if the chain struggles to reach the smallest cog.
Setting the Low Limit Screw (L-Screw)
The L-screw prevents the chain from overshooting the largest cog.
- Shift to the largest rear cog.
- Turn the L-screw clockwise to move the jockey wheel away from the cog.
- Turn counterclockwise if the chain struggles to reach the largest cog.
Adjusting B-Tension for Proper Clearance
The B-tension screw controls derailleur clearance from the cassette.
- Increase B-tension to create more space if shifting feels sluggish.
- Reduce B-tension to improve chain wrap on the largest cog.
Fine-Tuning Indexing with Barrel Adjuster
- Shift through all gears to test shifting.
- Turn the barrel adjuster counterclockwise if shifting is slow.
- Turn clockwise if the chain skips gears or shifts too far.
Troubleshooting Common Issues
1. Chain Skipping or Inconsistent Shifting
- Check if the shift cable is frayed or stretched.
- Re-index the derailleur with the barrel adjuster.
2. Chain Drops When Shifting to Smallest or Largest Cog
- Re-adjust the H-limit and L-limit screws.
3. Derailleur Cage Hitting Cassette
- Increase B-tension screw adjustment.
