ONE SERIES - 78
The fastest wheels for triathletes and time-trialists. ONE78 is a tubeless ready, full carbon wheelset. Aerodynamically optimized for 25mm tyres. It features a 78mm rim depth that makes this wheelset the fastest wheelset we've ever made. Composite filament winding technology provides optimal stiffness, weight savings, and durability – while GEN4 aerodynamic rim shaping allows riders to maintain stability in crosswind conditions.
technology
tubeless ready
ONE series wheelsets are tubeless ready for premium ride quality and increased flat protection (tubeless valve stems included with purchase).
advanced composites
700 series composites that are filament wound for optimal compaction and elimination of carbon layup error, resulting in a perfect rim every time.
aerodynamics
Building upon our aerodynamic GEN3 profile, GEN4 rim shaping allows for greater efficiencies with modern 25-28mm tyre selections.
