Zipp 858 NSW Disc Brake Road Wheels Description:

The Zipp 858 NSW Disc Brake Road Wheels are a super deep aerodynamic road system designed for triathlons, time trials, and for anyone else who feels the need for speed. These wheels feature Zipp’s Carbon Internal Reinforcement construction, which creates a rim that is lighter than previous versions of this rim, while maintaining impressive strength and stiffness. On the inside of the rim, there is a 23mm wide inner rim channel with a hookless and tubeless compatible sidewall. This hookless design creates a seamless tire interface for improved aerodynamics, provides better support for larger volume road tires, and thanks to the increased air volume, these rims will increase comfort, traction, and flat prevention. Not to be outdone, the outside of these rims feature a unique Sawtooth variable height rim profile, fin shaped Hyperfoil nodes on the inner diameter of the rim, and HexFin ABLC dimple pattern that work with the gains from the hookless sidewalls to create some of the most aerodynamic wheels, not only in a straight line, but these technologies also work together to direct crosswinds more efficiently through the wheels to reduce the sideways push of those hated crosswinds.

In the middle of these impressive wheels are Zipp's Cognition V2 hubs, which utilizes a lightweight, premium alloy hub shell to keep the unsprung weight low, and these hub shells are filled with low friction sealed bearings for minimal drag and easy maintenance. The rear hub features a unique clutch drive mechanism to further reduce drag, and this design also engages very quickly for rapid power transfer regardless where the rider is in their pedal stroke. Super light, bladed Sapim CX-Ray stainless steel spokes and alloy nipples tie everything together and further aid in the overall aerodynamics of these wheels. Put all of these impressive features together, and the result is a comfortable, durable, and super aerodynamic wheel system that will get the rider to the finish line faster than ever before.

Note: Max total system weight rating (this includes the weight of the rider, the bike, and all accessories) for these wheels is 250 lbs. Manufacturer recommends using tires that are designed for hookless rims, and max tire pressure ratings for these wheels are 73 PSI for 700x28c width tires, and 65 PSI for 700x32c width tires.


Features:

  • Zipp's Carbon Internal Reinforcement technology and hookless rim profile ensure structural areas of the rim are properly reinforced but removes material from where it isn't needed to lighten the overall weight of the rim and maintain overall strength and stiffness
  • Sawtooth rim profile with a variable 82-85mm rim height and HexFin ABLC dimple pattern on the sides of the rim create incredible straight line aerodynamics and stability in crosswinds
  • Hookless rim design has a seamless tire interface to help the air slide over the wheel/tire system easier, and the rim sidewall shape better supports the tire at lower tire pressures for better grip through corners, a smoother ride that preserves energy for longer bike rides or the running portion of a triathlon, and improved flat prevention
  • Generous 23mm inner rim width offers better support for higher volume tires; this rim is optimized for 28mm tires but will fit tires between 28 - 32mm in width
  • Bladed Sapim CX Ray stainless steel spokes boast incredibly high tensile strength and stiffness, and an aerodynamic spoke profile helps the wheel to slice through the air
  • Zipp centerlock disc compatible Cognition V2 hubs use premium sealed bearings to minimize friction, and the rear hub features an Axial Clutch V2 mechanism for quicker engagement, minimal drag, and impressive durability
  • Proudly made in the USA at the Zipp headquarters in Indianapolis, Indiana
  • Wheels will include centerlock rotor lockring, but will not include rim tape or tubeless valve stems
