The Ritchey Switch System is an innovative integrated system designed to easily conceal internally routed cables, wires, and hydraulic lines from the handlebar into bicycle frames with straight 1.5" head tubes together with tapered 1-1/8" – 1.5" forks. The front of the Ritchey WCS Switch stem features the tried-and-true Ritchey C220 handlebar clamp design seen on many Ritchey stems, but we've increased its width for additional stiffness. We’ve also rotated the clamping area a few degrees downward to create a flatter and more aerodynamic top stem section. The front of the WCS Switch stem also includes a reversible accessory mount. Designed to accommodate accessories such as cycling computers, cameras, and power meter head units, this mount is completely hidden within the front clamp of the stem until you decide to mount your favourite accessory. Features Integrated cable routing: Conceals up to three cables (brakes, shifters, electronics) within the stem and integrates seamlessly with the Ritchey Switch Headset and Spacers. C220 handlebar clamp: Utilizes a proven, wider design for increased stiffness and support, with a 31.8mm clamp diameter. Accessory mount: Includes a hidden, reversible mount on the front of the stem for accessories like cycling computers, cameras, or power meters.
