Retrogression Gold PVD track cog

CNC machined from hardened, heat-treated stainless steel and featuring a PVD processed titanium nitride coating.

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.

Sizes 17t-19t have cutouts for weight savings.
