RITCHEY headset upper part Logic-E 1 1/8 "ZS44 / 28.6
Tom Ritchey brought Ritchey's legacy of legendary bicycle products to the world of e-bikes and electronic gears.
He designed a headset that would allow the cables to be routed internally from the stem to standard frames without having to modify the frame or fork. The Logic-E headset enables Shimano Di2 and STEPS cables to be protected from sight, wind and damage.
