About this 3D model

A worn chain wears sprockets at an accelerated rate. Gauge is designed to accurately indicate when a chain reaches .5% and 1% "stretch," the points at which most chain manufacturers suggest replacement. KTM recommends replacing the chain when the “stretch” is 0.85% or more. Bolt&Nut M3x12mm Easy to use, fast to print. Works with 520 chains.
