Seatpost clamps take abuse every time you adjust saddle position, and the single-bolt designs on Ritchey WCS posts use a specific interface that generic hardware won't match. The WCS Alloy 1-Bolt Clamp Kit provides the complete replacement assembly for Ritchey's single-bolt seatpost heads, giving you fresh hardware when threads strip, bolts round out, or clamp faces wear from repeated adjustments. This is the same clamp assembly that ships on WCS-level posts, not an aftermarket approximation.

The kit includes the alloy clamp body, bolt, and associated hardware needed to restore full function to a worn seatpost head. Ritchey machines these clamps to the same tolerances as original equipment, which matters when you're dealing with the clamping forces required to keep a saddle from shifting under load. If your current clamp has developed play, shows visible wear on the contact surfaces, or the bolt threads have started to feel rough, this kit addresses all three issues simultaneously.

Sizing corresponds to Ritchey's seatpost clamp dimensions, so you'll need to identify which version matches your specific WCS post model. The three variants in this kit cover different rail clamp configurations within the WCS lineup. If you're unsure which size fits your post, the markings on your existing clamp or the original post specifications will confirm compatibility.... Read More
