Left chain tool Lezyne

Product Description

Sensitive and elegant, the Chain Gauge is a multi-functional bike chain checker with an integrated chain hook and wear indicator as well as a convenient valve core removal tool. Compatible with most 5 to 12 speed bike chains and precision machined for superior accuracy, the Chain Gauge is a stainless steel insurance policy against premature drivetrain wear. Hang it near your repair rack with the included ring so you never go too long without checking your chain wear again, and don't forget to put it back on after you break a cold one with the built-in bottle opener.
