RITCHEY headset upper part Logic-E 1.5" ZS56/28.6
Tom Ritchey brought Ritchey's legacy of legendary cycling products to the world of e-bikes and electronic shifting.
He designed a headset that would allow the cables to be routed internally from the stem into standard frames without having to modify the frame or fork. The Logic-E headset makes it possible to protect Shimano Di2 and STEPS cables from sight, wind and damage.
