The Super B Chain Checker & Hook quickly and accurately shows chain wear, so you replace your chain before it damages your cassette and chainrings. It fits 5 to 13 speed chains, including SRAM T-Type, SRAM Flattop and Shimano XTR 12 speed.
Replacing a chain on time is far cheaper than replacing a worn cassette and chainrings. A chain checker takes the guesswork out, and this one also works with the latest 12 and 13 speed chains.
