Chain Wear Checker
$28.00
Think your bike chain’s fine? Think again. If you enjoy grinding gears and shredding your wallet on new cassettes, skip this Chain Checker. But if you want to avoid turning your ride into a scrapyard of worn-out parts, just stick those pins into two links and let this little gadget tell you how stretched your chain really is. Works with almost any chain, yes, even that fancy Shimano XTR 12-speed one you brag about. Or don’t, and keep pretending your bike shifts perfectly while your chain falls apart. Your call.
