Ritchey: You really can have it all—the WCS C220 stem rivals the performance of the revolutionary C260 stem design, but it's quicker and easier to install and remove thanks to a press-fit handlebar clamp interface and forward-facing hardware.The WCS C22 84D Stem offers 6° of positive or negative rise. First proven on the Ritchey Trail Stem, the C220 handlebar clamp design creates a more secure interface by wrapping a full 220° over the handlebar. Bolt forces are aligned with the clamp so that the stem body 'embraces' the handlebar, which is less prone to damaging lightweight bars. This clamp design allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness.The stem body is forged 2014 aluminum for further weight reduction. Premium quality stainless steel black bolts are used throughout.6° of positive or negative rise1-1/8 or 1-1/4 steerer diametersStem body wraps 220° around bar clamping area, holding it in place for easy installation Material: 2014 alloyBolts: stainless steel blackLengths: 60-140mmAngle: 84°/6°Bar clamp diameter: 31.8mmBar clamp width: 44mmSteerer diameter: 1-1/8 (28.6mm) or 1-1/4 (31.8mm)Steerer height: 42mm (1-1/8) - 44mm (1-1/4)Weight: 132g (100mm - 1-1/8)Colour: Blatte Warning: 1-¼ stems ship with a cosmetic spacer.
