MK0 items represent a refined approach to component engineering, with special consultation with Team Visma Lease A Bike. Each top cap spends 4x more time in Wolf Tooth's CNC lathe, before undergoing thorough QC inspection, and anodizing in the new Shadow Gray color. The extra machining and new profile of the MK0 upper headsets have meaningful gains and result in a 44% reduction in aluminum weight without compromising strength and durability. These super slammed 4mm stack upper headsets feature extraordinary sealing to prevent water intrusion and provide protection for the premium Enduro stainless steel sealed bearings.
