Ritchey WCS C260° Wet Black Stem

The WCS (World Championship Series) line is the gold standard for lightweight, bombproof race parts and cutting edge innovation. The rainbow stripe WCS logo represents the numerous world champions that have won on Ritchey. Ritchey’s revolutionary, patented 260-degree stem clamp design brings a new level of stiffness, trength and weight savings to 3D forged alloy stem. The 260 degree clamp distributes clamping stress more evenly through the stem body, faceplate, hardware and handlebar.

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 and internally machined for further weight reduction. Premium quality CrMo steel bolts are used throughout, but in a smaller M4 size that shaves a few more grams with no sacrifice in strength or rigidity.

The resulting CEN-approved stem is 20 grams lighter and even stiffer than our already stiff and lightweight 4Axis.
