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 220° around the handlebar. 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 faceplate and a lighter stem body without compromising 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 inch • Angle (in °): 6 ° stem • Design: Ahead Mass • Handlebar clamp (mm): 31.8 mm • Material type: Aluminum.
