KMC's digital chain checker takes chain evaluation to the next level by accurately quantifying the wear in a precise, repeatable method. This custom digital micrometer measures up to 2.5mm of elongation over four full chain links, and is accurate to 1/100th of a millimeter. Features include an on/off switch, zero calibration, metric/imperial switch, and a slide lock screw. The face is printed with clear wear ranges for quick evaluation of chain wear. Each digital chain checker includes a protective case, two LR44 batteries (one for initial installation and one spare) and a screwdriver to access the battery compartment.
This chain checker is compatible with all 1/2" pitch chains from single to 11 speed, and functions well with chains from all manufacturers, including Campagnolo, Sram, Shimano, and KMC.
