85mm — the deep-section specialist

The 85mm DICUT toroidal profile is engineered for the lowest aerodynamic drag at competitive road speeds. On flat and rolling roads, the depth advantage compounds over distance — making it a significant performance gain in time trials and triathlon transitions. The toroidal shaping helps manage crosswind stability compared to traditional deep-section profiles.

240 DICUT hub and Ratchet EXP

The 240 DICUT rear hub delivers fast, reliable engagement via the 36-point Ratchet EXP star ratchet. The freehub body is field-swappable between Shimano HG, SRAM XD, and Campagnolo standards.

WTS — Wheel Tuning System

Valve stems, rim tape, spare nipples, and Ratchet EXP ratchet components are bundled in the WTS kit for long-term service readiness.

Compatibility

Disc brake road and triathlon bikes. Rear axle: 12×142mm. Freehub: Shimano HG, SRAM XD, or Campagnolo — specify at purchase. Tubeless or clincher tyre compatible.
