You can truly have it all - the WCS C220 stem matches the performance of the revolutionary C260 stem, but can be installed and removed faster and easier thanks to a press-fit handlebar clamp interface and forward-facing hardware. The WCS C22 84D stem offers a 6° positive or negative rise. The C220 handlebar clamp, which was first proven in the Ritchey Trail stem, creates a more secure interface by wrapping around the handlebar a full 220°. The screw forces are directed onto the clamp, allowing the stem body to "hug" the handlebar, making it less prone to damage on lightweight handlebars. This clamp design enables a lighter front plate and a lighter stem body without sacrificing strength or stiffness. The stem body is made from forged 2014 aluminum for further weight reduction. High-quality stainless steel screws are used throughout in black. • Intended use: Road bike / Cyclocross • Steerer tube diameter: 1 1/8 inches • Angle (in °): 6° stem • Design: Ahead standard • Handlebar clamp (mm): 31.8 mm • Material type: Aluminum.
