Zipp 454 NSW Carbon Clincher Tubeless Disc Brake Wheel

Zipp's ultimate all-around speed weapon is now tubeless ready. That means you get all of the aero advantages of the 454 NSW Tubeless Disc-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The wheelset's 19mm internal width is optimized for running wider tubeless tyres at reduced air pressure. The 454 NSW's undulating 53/58mm-deep rim shape, our proprietary Sawtooth profile, takes design cues from nature for our highest performing wheel when it comes to aero efficiency and crosswind stability. A humpback whale's fast and graceful movements are aided by tubercles on its pectoral fins. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil nodes, that reduces both aerodynamic drag and side force. Combined that with tubeless compatibility and the power of disc brakes, and you are set for the ultimate in Zipp performance

Technologies

Cognition Hubset - With the cognition hubset's axial clutch technology, we've reduced this drag by disengaging the rachet mechanism when coasting.

So you can approarch corners at higher speeds and ultimatley save time.A star flanged straight pull hubshell design on the rear hub distrtibutes the load placed on the hub flange away from the bearings.We've also developed a unique scalloped edge hubshell design for our front hub.This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied.That means you get bearings that quietly stay in place , roll faster , last longer and provide a laterally stiffer hub

Impress - We've employed Zipp's ImPress graphics technology , which prints directly on the wheel, to help allow the dimples to do what they were designed to do - help control vertex shedding ,the rate at air sheds off the wheel.Managing this is crucial to stability.ImPress graphics also give NSW s distinctive stealthy look.

Sawtooth - Sawtooth is the name given to Zipp's patented variable depth 53/58mm rims.Developed utilizing the principles of the emerging science of biomimicry.Zipp engineers began the rigorous aero development process of sawtooth utilizing the wind tunnel ,CFD and the real world testing.The result is a rim shape that takes nature's most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before.This patented new rim shape achieves something conventional aero wheels cannot,it simultaneously reduces bothaerodynamic drag and side force for the ultimate in AeroBlance.Sawtooth accomplishes this with a series of patented fin shape Hyerfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improves airflow.The result is Zipp's highest performing wheelset ever realized with both aero drag reduction and reduced side force at all wind yawl angles.This is important becuase higher wind yawl angles are where bike handling is most effected by the wind.
