Ritchey: The front of the new Ritchey 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. Beyond that, everything else on this innovative stem is new and designed to stealthily conceal cables into the headset and frame.

The Ritchey Switch Stem includes a matching compression cap.About the Ritchey Switch SystemThe 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.
