Ritchey WCS Switch External Cup Headset - 33050817002

A key component of the new Ritchey Switch System, Ritchey's newest headset upper is designed to specifically work with 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 44 mm headtubes together with tapered 1 1/8" — 1.5" forks.
