An accurate way to check for wear of roller & pin on chains 1% of wear is enough to affect chainrings & sprockets & allow shifting performance to deteriorate Just insert the chain Checkers pins into two links press the swing arm gauge & then check the gauge window for an accurate reading Reads wear from 0.25% to 1%10-speed compatible ...

A worn chain shifts poorly & wears sprockets at an accelerated rate The CC-3 is a Go / No-Go gauge designed to accurately indicate when a chain reaches 0.75% & 1% wear
- the point at which most chain manufacturers suggest replacement The chain should be replaced soon if the 0.75% side fits into the chain before other drive train components also start to wear out fast If the 1% side fits into the chain the chain is worn out & should be replaced immediately Made from precision laser cut steel Consider that if you replace a chain because of wear other vital drive-chain components may need to be renewed too 10-speed compatible

A dirty drivetrain causes poor shifting & unnecessary wear to expensive parts. The CG-2.4 contains everything needed to quickly & easily clean the chain cogs & chainrings: CM-5.3 CYCLONE™ CHAIN SCRUBBER Clean bicycle chains quickly easily & effectively without the hassle & mess of removing the chain from the bike. The CM-5.3 uses an extra-large solvent reservoir & a series of four rotating brushes to get chains sparkling clean inside & out. A magnet at the bottom of the CM-5.3s solvent reservoir draws away particles scrubbed from the chain effectively keeping them from being redistributed on the chain during cleaning. The durable sponge material draws solvent from the chain as it exits the CM-5.3 reducing drips & mess. The CM-5.3 can handle any bike-specific chain from wide 3/16 single-speed* to narrow 12 & 13-speed. A reversible handle allows the chain to pass through forwards or backwards for compatibility with center drive e-bikes.
