The C260&176; Stem - At 103 grams this is lightest, most advanced alloy stem in the Ritchey line, & possibly the world. 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 & stem body. The steer tube clamp uses three bolts & a curved slot to reduce clamp stress on the steer tube. The body is 3d forged from an advanced 7050 aluminium & internally machined for further weight reduction. Premium quality Cr Mo 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 & even stiffer than our already stiff & lightweight 4 Axis.
