The Zipp 858 NSW Disc Tubeless Wheel is the ultimate aerodynamic wheel that can hit blazing speeds on the road. It also features a huge drop in weight compared to previous models. This wheel features the deepest rims in Zipps entire lineup at 85mm. An undulating rim features Zipps patented Sawtooth Profile. This helps the wheel be more than just aerodynamically efficient against headwinds. It can remain stable and efficient against crosswinds as well. Zipp used their Total System Efficiency Technology to update this wheel and conquer the four speed barriers. Wind, gravity, rolling resistance, and vibration loss are all mitigated with the new technology in the 858 NSW. This is perfect for a triathlon or time trail rider who needs aero efficiency at very high speeds. It is also an excellent option for an aggressive road rider who likes to push the pace. The low friction Cognition V2 hub will keep the speed going when not pedaling.

In modern cycling, pure speed is not enough. Compliance and control are huge factors in maintaining high speeds over a long period of time. An 23mm internal rim width allows for wider tires to be run which leads to better grip for fast cornering. This wheel also runs tubeless tires which can utilize a lower tire pressure for extra compliance. The added comfort can keep riders feeling fresh, helping them go faster over long rides. A hookless interface and optimized tire bed creates easy installation. 25mm is the minimum tire width that can be equipped. The 858 NSW Tubeless Disc Wheel represents the pinnacle of Zipps aerodynamics and speed and is a perfect choice for a triathlete, time trial rider, or fast road rider.
