Ritchey Classic Toyon Stems - 31.8 Clamp 60mm 6 deg SilverRitchey Classic Toyon Stems 31. 8 Clamp 60mm 16 Silver. The Classic Toyon retains the clamping surface area of the C220 which creates a more secure interface by wrapping a full 220 over the handlebar. Its bolt forces are aligned with the clamp so that the stem body embraces the handlebar a design which is less prone to damaging lightweight bars and allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness. Perfect match
