RITCHEY Upper Switch Comp Cartridge Drop In 1.5 IS52/28.6

A Key Component Of The New Ritchey Switch System, Ritchey´s Newest Headset Upper 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.
