- Test cable rigidity: If the chain is not shifting easily onto bigger cogs, you would possibly want extra cable rigidity. Flip the barrel adjuster counter-clockwise so as to add rigidity.
- Set restrict screws: These stop the chain from dropping off the cassette into the spokes or body once you shift gears.
- The H-screw (excessive restrict) adjusts how far in direction of the surface of the bike your derailleur can transfer and must be set in order that when in your highest gear, there’s about 1-2mm between your largest cassette cog and your jockey wheel.
- For setting low restrict (L-screw), shift to the biggest cog at again and modify till there’s an identical hole of 1-2mm between jockey wheel and cog.
Subsequent up is indexing gears which entails fine-tuning every gear change:
- Shift by means of every gear slowly whereas turning pedals ahead, listening out for noises or hesitations which point out misalignment.
- Use barrel adjuster tweaks as earlier talked about; flip clockwise for much less rigidity if leaping too far previous meant cog or counter-clockwise if struggling to climb onto subsequent larger cog.
