Description
The Ritchey Comp Logic-E Upper Drop In Headset allows electric cables to be run internally from the stem into standard frames without requiring the frame or fork to be modified.
Bringing Ritchey's heritage of legendary cycling products into the world of e-bikes and electronic shifting, Tom Ritchey designed this unique headset.
The Logic-E headset is designed to allow Shimano Di2 and STEPS cables to be concealed from view and the wind while protecting them from damage and is available for drop-in and press-fit standards.
For 1"1/8 steerer tubes.
