Ritchey WCS C260 Wet Black StemThis 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.
This is a great stem with an attractive high gloss (wet) finish. The clamping system works great and the handlebar seems to be held very firmly. The only issue is when you use it with a bar that has the flat top hand positions. Since the clamp wraps around 260 degrees of the bar you need to put the bar into the clamp near the drops where it is narrower then slide it over. the oval shape of the flat top bar doesn't want to slide through the round opening. Other than that one problem, this stem has been flawless.
