Ahead of the Ironman world championships in Hawaii, Zipp has rolled out its latest incarnation of the humpback-whale-inspired aero wheels with the 858 NSW. The deep aero hoops fluctuate in rim depth from 77 to 88mm, and will come in clincher and disc-brake models in November for a whale of a price at $4,400 / £3,730.

In early 2016, the SRAM-owned company introduced a magnet-based (instead of spring-based) freehub with the Zipp 404 NSW wheels.

Then, at the end of 2016, Zipp debuted the humpback-whale-inspired shape with the Zipp 454 NSW.

The new Zipp 858 NSW has both the magnetic Cognition hub and the undulating, textured rim, but in a super-deep format targeted at triathletes and time-trial aficionados.
