The TL-CN42 Chain Wear Indicator is a precision laser-cut measurement tool for assessing chain elongation across 7- to 11-speed systems, compatible with HG, IG, and UG chain types. The three-pin design accurately gauges wear at critical thresholds of 0.5% and 0.75%, enabling timely chain replacement before cassette and chainring damage occurs. Indispensable for proactive drivetrain maintenance and extending component lifespan.
Features:
- Provides high-precision measurement by checking without a gap between the roller and pin.
- Compatible with 7, 8, 9, 10, and 11-speed drivetrains.
- Constructed from hardened steel for longevity.
- Accurately identifies when a chain should be replaced to protect cassette and chainring lifespan.
- Tough genuine Shimano tools
