The new Ritchey WCS Toyon stem takes its lead from the original, award-winning Ritchey C220 stem and gives it a more modern shape and increased stiffness for improved handling and greater responsiveness. The 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 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. Built from life and all that inspires it, the Toyon builds upon the proven and celebrated C220 design with a fresh, squared aesthetic that adds to the overall harmony of modern frame designs—matching its good looks with enhanced confidence and a more lively feel for wherever your rides take you. - Matching top cap included - 6° of positive or negative rise - 1-1/8" steerer diameter - Stem body wraps 220° around bar clamping area, holding it in place for easy installation - Material: 2014 alloy - Bolts: stainless steel black - Matching top cap included - Angle: 84°/6° - Bar clamp diameter: 31.8mm - Bar clamp width: 44mm - Steerer diameter: 1-1/8" (28.6mm) - Steerer height: 42mm - Weight: 140g (100mm)

RaceFace designed their Atlas 35 stem to reduce overall system weight while retaining the proven stiffness and performance the Atlas line is known for. The stem itself is measurably stiffer than the 31.8mm offering and, although the system is a seemingly burlier build, the weight savings gained by the reduction in bar material actually makes the 35 system lighter overall. An impressively light, strong addition to your aggressive trail or DH/FR build. - Four-bolt bar clamp holds bar securely in position - Interlocking U-Shaped Handlebar Clamp Geometry - Faceplate eliminates stress risers which cause your bar to bend or break - Opposing bolts on steer tube clamp provides extreme clamping power while reducing stress on the steer tube - Stack Height: 40mm

Your stem may seem inconsequential, but it is the point of transfer between your skilled handling and the bike itself. An impressive refinement of our popular top level Easton alloy stem, the 2019 EA90 stems have an larger boom diameter for increased stiffness and, by utilizing our highest quality alloys, we were able to remove excess material for even more weight savings. We’ve also created a custom computer mount (included with EA90 stems and sold separately) that is compatible with all ICM faceplate stems for cleaner lines and improved aerodynamics. With lengths ranging from 70mm to 130mm, we can accommodate fits for all sizes of frames and riders. We shaved our new EA90 down to 120 grams for a 100mm stem and, with weights like these, we surpass much of the alloy and carbon competition in the market, while giving you the durability, confidence and control you expect from Easton. - Finish: Black Ano - Weight: 120g (100mm) - Rise: +/- 7-deg - Clamp diameter: 31.8mm - Steerer: 1 1/8-inch - Length: 70mm, 80mm, 90mm, 100mm, 120mm - Materials: EA90 alloy - Tech: ICM compatible (faceplate mount included), Top Lock, Taperwall
