Zipp 858 NSW Carbon Tubeless CL Disc Wheelset
With a design that majors on unadulterated speed, the Zipp 858 NSW Carbon Tubeless CL Disc Wheelset is the perfect pick for when chasing a PB in an effort against the clock or when aggressively attacking a flat to gently undulating road race.
The rims are realised in the finest carbon fibre to guarantee an exceptional stiffness to weight ratio and use an innovative, undulating SawTooth profile. This profile utilises Hyperfoil nodes along its inner circumference to vary the rim depth between 77 and 82mm. By doing this, aerodynamic drag is slashed while simultaneously stabilising crosswind handling. The SawTooth profile also increases the rim’s lateral stiffness and strength, while the HexFin ABLC surface dimples help to further cut wind resistance.
Zipp’s own Cognition V2 hubset spins smoothly on high-quality, durable bearings, and its Axial Clutch freehub dramatically reduces resistance when coasting and provides near-instant pedalling engagement. The build is linked together with Sapim CX-Ray spokes arranged in efficient and reliable two-cross lacing patterns.
Includes
- 12mm hub end caps
- Center Lock lock rings
Highlights
- A wheelset ideal for riders focused on triathlon, time trials, or aggressive road riding
- The rims use the highest grade of carbon fibre to lower weight, increase strength and improve lateral stiffness
