A worn chain shifts poorly and wears sprockets at an accelerated rate, the Chain Wear Indicator is designed to accurately indicate when a chain reaches 0.5% and 0.75% wear - the point at which most chain manufacturers suggest replacement.
- Replace chain if the 0.75% side fits into the chain
- Other drive-chain components may need replaced
- Longer design for greater length of chain
- 10-speed compatible
- Laser cut steel
