MK0 items represent a refined approach to component engineering with special consultation with Team Visma Lease A Bike. MK0 Centerlock Rotor Lockrings feature a new design language and an exclusive color. For this new aesthetic, each premium lockring spends extra minutes in a CNC lathe before undergoing thorough QC inspection, anodizing in the new Shadow Gray color, and branding before it can be installed on a hub.
