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. Up to four cables – such as for the rear brake, shifter, or electronics - are situated within a unique enclosed channel on the underside of the stem, which then effortlessly integrate with the Ritchey Logic-E 1.5" headset – cleanly routing the cables into the frame. The Ritchey Switch Stem includes a matching compression cap. Features 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. 3D Net Shape Forging - Process that forces the material grain to follow the product shape for greater structural strength.
