Ritchey WCS Toyon Stem C220 Engineering, Squared Up Road and gravel riders who want the proven grip of Ritchey's C220 clamp in a stem that fits modern frame aesthetics have a strong option here. The Toyon evolves the C220 design with a sharper, squared-off profile and stiffer construction for more responsive handling. The clamp wraps 220deg around the bar, aligning bolt forces so the stem body embraces the handlebar rather than crushing it, which means your lightweight carbon bars stay safe without giving up any security at the interface. Features C220 handlebar clamp wraps 220deg around the bar for a secure interface that protects lightweight bars from clamp damage Bolt-force alignment clamp geometry directs clamping load to embrace the bar, allowing a lighter faceplate with no loss in strength or stiffness WCS-tier construction increased stiffness over the standard C220 for sharper, more responsive handling Modern squared aesthetic profile designed to complement current road and gravel frame geometry Handlebar Clamp Diameter 31. 8mm Steerer Clamp Diameter 1-1/8" (28. 6mm)Specifications Handlebar Clamp Diameter31. 8mm Steerer Clamp Diameter1 1/8"Length60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm Rise / Angle+/- 6Clamp Width44mm Stack Height42mm Material2014 Alloy Weight139g (100mm)Intended Use Road, Gravel | Ritchey | Wcs Toyon Stem | Blatte | 110Mm, +/- 6 Degree | Aluminum
