Quick Overview

The fastest wheelset in all wind conditions is inspired by nature

Details

Color: Carbon Fiber with grey Zipp logos 

Size: 700c

The wheels of a bicycle are always affected by the wind. How they are affected makes a very big difference in overall performance, whether in road races, triathlons or "challenge" rides. Since the bicycle/rider combination almost never rides perfectly straight into the wind, Zipp looked at how an aero wheelset can still make a performance difference when faced with a wider range of wind angles. First, they looked to nature for inspiration...

The fins of an 80,000 pound humpback whale have a rippled edge that allows them to propel themselves through ocean currents with very little effort. Zipp took this whale's fin shape and refined it for their newest 454 NSW wheelset using Computational Fluid Dynamics (or CFD) software. The sawtooth shape -called Hyperfoil by Zipp- of the 454's rim keeps the airstream less turbulent as it passes over the rim at an angle, making it more stable in crosswinds while still keeping aerodynamic drag very low. The rim's Hyperfoil shape is complimented with a refined rim dimple pattern that Zipp calls HexFin. The Aerodynamic Boundry Layer Control dimples -or ABLC- stabilizes the air as it passes over the rim surface, making it more stable in crosswinds than a smooth surface. The Zipp 454's HexFin rim dimples have a carefully refined pattern that guides the airstream to the sawtooth Hyperfoil shape, managing aerodynamic drag better. These two technologies work together to make the Zipp 454 wheelset incredibly stable in crosswinds and boast very low drag numbers in a wider range of wind conditions. No other wheelset in the industry can do what the Zipp 454 wheelset does.

Zipp constructs the rims of the 454 NSW wheelset by hand in Indianapolis, ensuring very precise quality control throughout every step of the manufacturing process. Using Sapin CX-Ray bladed stainless steel spokes, the Zipp 454 wheelset is handbuilt by experienced professionals. The Zipp Cognition hubset is manufactured in Portugal, and is exclusively used with Zipp's finest NSW wheelsets. The Cognition freehub uses an Axial Clutch ratcheting mechanism that reduces coasting drag by 50% compared to classic 3-pawl ratchet drive hubs. How? By using magnets to re-engage the cassette body ratchet when the rider begins pedaling. Cool, huh? The rear hub shell uses a staggered stacked lacing pattern of the spokes to keep the lateral stiffness of the wheel high. During hard efforts and sprints, the Zipp 454 NSW won't get rubbery underneath the rider. Up front, the scalloped hub is built to resist spoke stress on the bearings during sprinting and cornering, keeping the Swiss-made bearings rolling smoothly.

Braking wasn't overlooked, and Zipp made sure to include their refined Showstopper braking tracks on the 454 NSW wheelset. Showstopper refers to a mixture of technologies that Zipp spent 2 years developing with in-house prototypes that were tested by athletes in real-world conditions. First, the rim's braking track features a directional, molded-in surface with grooves that help disperse water much better than an ungrooved rim. Second, the surface itself is embedded with silicon carbide particles in the braking track's refined resin. The resin used in the braking track disperses heat more effectively than previous versions, preventing serious overheating in the tire/tube combination.

The Zipp 454 NSW wheelset includes: Tangente Ti skewers, Zipp rim tape, Zipp Tangente inner tubes, Zipp wheel bags, valve extenders by Silca and Platinum Pro Evo brake pads.

No charges for installation of tubes, tires and cassette with the purchase of this wheelset at Machinery Row Bicycles.
