Description

The RITCHEY LOGIC-E IS52/28.6 Integrated Headset Upper Cup is an integrated upper headset assembly designed to route cables and wires into the frame with any standard stem, without requiring a specific stem. The cables enter through channels in the cup, then pass between the fork steerer and head tube before entering the frame.

Made from glass-fibre-reinforced nylon, it includes a 51.85/40 mm 45°/45° sealed cartridge bearing and has a stack height of 20.2 mm and a weight of 93 g.

Designed for head tubes with a 52 mm internal diameter (IS52/28.6 standard), it requires a bearing insertion depth of 8.7 mm: check compatibility with the frame manufacturer.
