A key component of the Ritchey Switch System the WCS Switch External Cup Headset is designed to specifically work with the Ritchey Switch Stem to route cables wires and hydraulic lines from the handlebar through to the bicycle frame. Cables are routed from the handlebar into the headset conduit which sits on the underside of the Switch Stem and then travel through an opening on the front of the Switch headset spacers before passing through two channels on the top of the headset and into the frame. This system allows headset bearings to perform without any interference from cables wires or lines passing through the headtube.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 Switch System consists of three elements: Switch Headset Headset Spacers and Adapters (Sold Separately)
