Press Fit Logic-E 1-1/8" upper headset
Intended use: STEPS or MTN Di2 integration
Compatible with frame headtubes 1-1/8" (ZS44/28.6) and optimized with Bar Logic-E
LOGIC-E CONCEPT: The Logic-E Integration Kit was designed to allow Shimano Di2 and STEPS cables to be concealed from view and from the wind while protecting them from damage. Tom Ritchey designed a unique system that allows the cables to be run internally from the stem into standard frames without requiring the frame or fork to be modified. A flexible, adhesive, cable guide included with Logic-E headset, allows routing of Shimano cable under stem to top cap. The Di2 Integration Kit is compatible with any Ritchey stem. Thus, a wide variety of handlebars can be used.
