Park Tool CC-4.2 Drop-In Chain Checker

A laser-cut drop-in gauge that checks wear over a long section of chain and touches it in three places for a straight answer. It shows 0.5%, 0.75% and 1.0% wear, so it covers single-speed chains right up to 13-speed, including SRAM T-Type and Flattop, Shimano XTR 12-speed and Campagnolo Ekar 13-speed. Check your drivetrain maker's own advice too.
