All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: In this particular model stem we’ve tailored the Oversized strategy to favor utility and access. The geometry has been altered to allow for easy handlebar removal while at the same time scavenging material from low stress zones. Ideal for those who don’t want to compromise on user experience to gain performance. These stems are engineered for the larger-sized racers.

Key differences: In this particular model stem we’ve modulated the Oversized formula to emphasize pedaling stiffness. We have transferred material specifically to sectors that experience sudden stress from pulling up on the handlebars. You’ll feel a difference in your acceleration.

Whether it's a cross remount, an unexpected pothole, or a rough line down the trail, the WCS Zero post will not relinquish its position. Featuring a confidence-inspiring extra-secure fore/aft bolt system, the Zero post is second-to-none in ease of installation and fit adjustment. - Fore/aft adjustment bolts for precision adjustment and secure clamping - 3D Forged 2014 Alloy - Offset: Zero - Cradle: Standard saddle rail clamp

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-degrees 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 degrees 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 CrMo steel bolts are used throughout. - Material: 3D forged 2014 alloy body - 4 x 4mm coated CrMo steel forward-facing faceplate bolts - 2 x 4mm coated CrMo steel offset steer tube clamp bolts - 5Nm torque max on all hardware - Compatible with all 31.8mm bars - Press-fit clamp design installs and removes like a standard stem - Angle: 84/6 degree - Steerer Height: 42mm - Faceplate Width: 42mm - Blatte finish - 121g (110mm)

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)
