Ritchey Upper headset with intergrated cartridge Logic-E

Bringing the legacy of Ritchey 's legendary products to the world of e-bikes and electronic shifting, Tom Ritchey has designed a unique headset that allows cables to be run inside the stem in standard frames without having to modify the frame or fork. The Logic-E headset is designed to allow Shimano Di2 and STEPS cables to be hidden from view and wind while protecting them from damage. It is available for both IS integrated and ZS semi-integrated standards.
