ชุดล้อดิสเบรคคาร์บอนครีบปลาวาฬ Zipp 454 NSW โม่ Sram XDR 12สปีด

Zipp considers their 454 NSW wheel to be ultimate road racing wheel. This speed and versatility oriented wheel balances speed, weight, and aerodynamics for the rider who wants to thrive in all areas. It is aerodynamically efficient and stable in all wind conditions, accounting for all possible wind angles. An undulating 58mm Sawtooth rim shape with Hyperfoils makes it the most aerodynamic and stable wheel on the market. It also includes Zipp Total System Efficiency which combats any enemies of speed. This includes wind resistance, rolling resistance, gravity, and body vibration losses. Mitigating all of these limiting factors leads to higher speeds with less effort and the fastest ride on the road.

This version of the 454 NSW wheel is over significantly lighter than its predecessor, making it more gravity defiant than ever before without sacrificing comfort or speed. The hookless rim featured on the wheel results in a more efficient resin distribution which results in a lighter and stronger wheel. The rim is also wider which allows riders to run tubeless tires at lower pressures, creating a more comfortable ride with vibration dampening and a lower rolling resistance. At the center of the wheel, you will find a Cognition V2 hub with an Axial Clutch V2 mechanism for quicker engagement, lower friction, and improved durability. The Zipp 454 NSW Disc Tubeless Wheel has all of your bases covered when it comes to elite performance on the road.
