Ritchey created the WCS C260 stem at only 103 grams which makes it the lightest, most advanced alloy stem in the Ritchey line. The patented design has a bar clamp that wraps a full 260° around the handlebar to distribute the clamping stress more evenly throughout the handlebar and stem body. The steer tube clamp uses three bolts instead of two to reduce clamp stress on the steer tube. The body is internally machined for further weight reduction.
