ZippÃ¢â‚¬™s advanced development lab, nicknamed Ã¢â‚¬Å“the NestÃ¢â‚¬Â, has turned to nature seeking solutions to the problems of speed, control and efficiency. Utilizing biomimicry, the Zipp 454 NSW Disc Brake Wheelset draws inspiration from an unlikely source: the humpback whale. This wheel showcases an evolutionary leap forward in rim design, and brings unparalleled braking control and responsiveness with it, to boot.
Zipp sought to address the all-too-common problem of crosswind instability. Any rider whoÃ¢â‚¬™s taken a pair of deep-dish wheels down an exposed decent has had the hair-raising experience of an unpredictable gust nearly resulting in a crash. This occurs because once the wind hits the rim, it results in low-frequency vortices creating whatÃ¢â‚¬™s called Ã¢â‚¬Å“buffetingÃ¢â‚¬Â.
The striking SawtoothÃ¢â€žÂ¢ rim architecture is ZippÃ¢â‚¬™s answer to pesky crosswinds. The biomimetic 53/58-mm deep rim takes inspiration from the tubercles on a humpback whaleÃ¢â‚¬™s fins. These tubercles provide the whale increased responsiveness as they corral krill, often changing directions or depths to position themselves perfectly. The 24 HyperFoilsÃ¢â€žÂ¢ along the 454 NSW rim address side-force by creating less powerful, more predictable high-frequency vortices. Pair this with the HexFinÃ¢â€žÂ¢ ABLC dimples for improved airflow and the result is ZippÃ¢â‚¬™s highest performing wheelset yet.
The 454 NSW rims are laced to the NSW-specific CognitionÃ¢â€žÂ¢ Disc hubs using 24 Belgian SapimÃ¢â€žÂ¢ CX-Ray spokes front and rear. Providing compatibility with Center Lock rotors, these wheels offer confident braking in all-seasons. The rear hub houses the XD-driver compatible Axiom Clutch freehub body, doing away with the standard 3-pawl ratcheting freehub body and opting for a drag-reducing 36-tooth magnetic-operated freehub that disengages while you coast. There is a star-flanged hub in the rear and a scalloped hub shell up front, increasing durability and reducing load on the stainless steel Swiss bearings.
