With the Ritchey Upper Comp Switch Integrated IS52/28.6, your cockpit gets a clean look and cable routing that stays out of the way even during long hours in the saddle. Steering remains light and smooth, even with hoses and wires routed internally into the frame.
The upper part of the headset is a key component of the Ritchey Comp Switch system, allowing internal routing from the handlebars directly into the frame. The cables run through dedicated channels, so they don’t touch the bearings or hinder the fork’s rotation.
Paired with the Ritchey Switch Stem, it creates a tidy setup for shift cables, electronic wires, and hydraulic hoses. Up front, there are minimal distracting loops—something you’ll appreciate in technical sections and when handling the bike.
The body material, a combination of nylon and fiberglass, keeps weight low while still handling the typical stresses around the head tube. The package also includes two system spacers, making it easier to dial in the correct stack height under the stem.
The integrated design for the IS standard helps maintain clean frame lines and precise component seating. If you’re building a modern gravel or road bike with internal routing, this is a detail that makes sense.
Intended use per S.H.I.S. designation: IS52/28.6 (1.5") for an integrated upper cup in the head tube.
For a head tube with an inner diameter of 52 mm and an outer diameter of 56 mm.
Bearings sized 51.90/40 mm with 45°/45° angles are semi-cartridge (SSC).
The weight of the upper part is 54 g, and stack height is 21.7 mm.
Ritchey Upper Comp Switch Integrated IS52/28.6 is the upper headset assembly for clean internal routing without restricting bearing performance. It suits frames with a straight 1.5" head tube and a fork with a tapered steerer from 1 1/8" to 1.5".
In the package, you’ll find the upper headset part and two 5 mm Switch spacers. The star nut and top cap are not included, so you can match them to your build.
