The Ritchey Logic WCS Switch External Cup EC Headset Description:

The Ritchey Logic WCS Switch External Cup EC Headset is designed to specifically work with the Ritchey Switch Stem to seamlessly route cables, wires and hydraulic lines from the handlebar into bicycle frames with straight 44mm headtubes together with tapered 1-1/8" – 1.5" forks. Initially the cables are routed through the handlebar and stem before travelling through an opening in the front of the Switch headset spacers. The cables then pass through two channels on the top of the headset and into the frame before they continue their journey through the frame to the brakes or the derailleurs. This system eliminates any interference with the bearings from cables, wires, or lines passing through the headtube.

Note: Cable guide is NOT included with this headset
