Chain compatibility: This will work with 7-12 speed chains.
How does it work: There are pictograph instruction on the side of the TL-CN42. The two steps are as follows:
- Drop the ‘split section’ labeled with the #1 into your chain (between two rollers).
- Pivoting off the ‘split-section’ try to drop the end labeled #2 into the chain. If it fouls on the roller the chain still has life left in it. If it drops into the chain. the chain is due for replacement.

Pros: Designed and manufactured by one of. if not the largest drivetrain manufacturer in the industry. You know it’s going to be quality.
Cons: This style of chain wear indicator doesn’t give you an indication of how much ‘life’ you have left in your chain. This simply tells you if it’s ‘good’ or ‘bad’.
