Zipp 454 NSW Carbon Tubeless

SKU : Zipp 454 NSW Carbon

he Zipp 454 NSW Disc is a very aerodynamic road wheelset with up to 58 mm high and 23 mm wide hookless tubeless carbon rims and the revised Cognition V2 hub set. The Axial Clutch V2 freehub ensures a faster frictional connection and less friction. Compared to the previous model, the weight of these wheels has been reduced by 400 grams.

Technology:

TSE™

Total System Efficiency is Zipp's approach to speed on different surfaces and under varying riding conditions. TSE aims to eliminate everything that works against speed: Wind resistance, inertia, rolling resistance and vibration.

NSW

NSW stands for " Nest Speed Weaponry." 'The Nest' is the nickname the Zipp engineers have given to the windowless high-security research laboratory in a corner of the Zipp factory. This site, or the ground-breaking ideas and designs that emerged from it, became the namesake for an entire series of wheels. The Zipp NSW series is a science, philosophy and mission to develop the fastest, most stable and highest performing wheel components of all times.

ImPress™

ImPress graphics not only provide valuable weight savings, but also allow for a unique and permanent application of Zipp's signature branding.

SawTooth™ ABLC HexFin™

This patented rim shape achieves what conventional aero wheels cannot: it simultaneously reduces aerodynamic drag and lateral wind forces, providing the ultimate AeroBalance™. SawTooth makes this possible through a series of hump-shaped Hyperfoil points along the inner diameter of the rim. Together with the HexFin ABLC dimples (hexagonal dimples), these provide improved airflow. The result is the most powerful Zipp wheelset of all times with lower aerodynamic drag and reduced lateral wind forces at any angle of attack. This is important because the steeper the wind angle, the larger the influence on the handling of the bike.

Axial Clutch V2

Every time you go into neutral, the pawl mechanism of the freehub on conventional hubs acts like a drum brake, costing you speed. The resistance between the hub shell and the freehub body during freewheeling leads to a loss of efficiency, especially on road bikes. As a solution to this, Zipp has developed the Cognition rear hub with Axial Clutch technology, which reduces drag by disengaging the gear mechanism when idling. The Axial Clutch Wave Spring, on the other hand, quickly and securely re-engages it as soon as the rider starts pedalling again. In the V2 version, this technology also results in even faster response, even less friction and improved durability.
