TRP, Chainring Lockring Kit

The TRP Chainring Lockring Kit is a factory replacement part for TRP's EVO carbon mountain bike crankset, designed to securely retain the chainring during hard riding. It's a simple, direct-fit small part that restores proper chainring retention when the original lockring wears out or is lost. This kit keeps your EVO carbon crankset running reliably without needing to replace the entire crank.
