Description
Moulding the finest carbon fibre into an innovative SawTooth rim profile, the Zipp 858 NSW Carbon Tubeless Rim Brake Rear Wheel shaves seconds when competing against the clock and saves energy when soloing away from the peloton. The SawTooth shape of the rim uses Hyperfoil nodes to alternate its depth between 77 and 82mm, striking the perfect balance of low drag and crosswind stability. HexFin rim surface dimples further improve aerodynamics, while the textured Showstopper brake track affords confidence-inspiring stopping power and control, even in the wet.
A broader inner rim width coerces tubeless-ready and standard clincher tyres into holding superior cross-sectional silhouettes, aiding them in lowering rolling resistance at reduced, comfort inducing inflation pressures. A smooth spinning Cognition V2 hub makes use of its Axial Clutch freehub to cut resistance while freewheeling and grant near-instant engagement under pedalling input. Sapim CX-Ray spokes complete the build and are laced in an efficient, reliable two-cross lacing pattern.
