Ritchey WCS Carbon Matrix C260 Stem

This revolutionary patented design starts with a bar clamp that wraps a full 260 degrees around the handlebar to distribute clamping stress more evenly through the handlebar, faceplate, hardware and stem body. The steer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube.

The body is 3D forged from an advanced 7050 aluminum, internally machined and then enhanced with a Ritchey Matrix structural carbon exoskeleton to enhance stiffness. Premium quality CrMo steel bolts are used throughout, but in a smaller T-20 Torx size that shaves a few more grams with no sacrifice in strength or rigidity.

The resulting CEN-approved stem is 14% stiffer than the WCS Alloy C260.
