ONE SERIES - 78
ONE78 is a tubeless ready, full carbon wheelset, aerodynamically optimized for 25mm tires. It features a 78mm rim depth that makes this wheel the fastest wheel we've ever made. It's the fastest wheel for triathletes and time-trialists. ACFW technology provides optimal stiffness, weight savings, and durability – while GEN4 aerodynamic rim shaping allows riders to maintain stability in crosswind conditions.
