The Zipp 858 NSW Disc Tubeless Wheelset is the ultimate aerodynamic wheelset that can hit blazing speeds on the road. It also features a huge 300+ gram drop in weight compared to previous models. These wheels feature the deepest rims in Zipp’s entire lineup at 85mm. An undulating rim features Zipp’s 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 Techology to update these wheels 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. These wheels also run 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 Wheelset represents the pinnacle of Zipp’s aerodynamics and speed and are a perfect choice for a triathlete, time trail rider, or fast road rider.
