CNC machined from hardened, heat-treated stainless steel and featuring a PVD processed titanium nitride coating, this lockring has a stepped design that prevents the chain from making unwanted contact with the lockring when using a 12t cog.

Titanium nitride (TiN) is an extremely hard ceramic material often used on medical devices, drill bits and precision saw blades to increase lifespan or function.

In addition to providing a beautiful gold plated appearance, this coating also improves surface hardness, prevents wear and reduces friction.

This will not fit Campagnolo, Miche, Phil Wood, Mack or Mavic hubs.
