A badly worn chain can quickly wear out cassette sprockets and chainrings. This gauge from Park lets you know exactly when the chain should be replaced thus extending the life of the other drivetrain components.
- An accurate way to check for wear of roller and pin on chains
- 1% of wear is enough to affect chainrings and sprockets, and allow shifting performance to deteriorate
- Just insert the chain Checker's pins into two links, press the swing arm gauge, and then check the gauge window for an accurate reading
- Reads wear from 0.25% to 1%
- 10-speed compatible
