Description

The RITCHEY COMP LOGIC-E ZS44/28.6 Semi-Integrated Headset Upper Cup is a press-fit upper cup designed to route Shimano Di2 or STEPS cables inside the frame without modifying the frame or fork.

With the Logic-E system, a flexible adhesive cable guide routes the cable beneath the stem to the top cap, protecting it from wind and impacts. It is compatible with Ritchey stems and optimised for Logic-E handlebars.

Made from aluminium for 1"1/8 steerers (ZS44/28.6 standard), it weighs just 44 g.
