Zipp 454 NSW Koło klinowe Tubeless Shimano 10/11/12-rz.

Derived from the 404 NSW, the Zipp 454 NSW wheelset with tubeless tyres redefines the aesthetics and behaviour of high performance wheels. You will be able to use wider tyres with reduced pressure thanks to this tubeless version. To create this unique wheelset, the brand's engineers looked at nature and were inspired by the humpback whale and the texture of a shark's skin, in order to find technologies to reduce the aerodynamic resistance and lateral forces to which any bicycle wheel is subjected. The result is quite surprising on this 454 NSW, which has a wavy, saw-tooth profile that varies in height between 53 and 58mm. On the surface, the rim features a HexFin ABLC golf ball-like coating with slightly recessed hexagonal patterns, which help reduce aerodynamic drag and improve stability in crosswinds.

Zipp's engineers have also paid particular attention to the hubs to further improve the aerodynamic behaviour of the whole by reducing turbulence with a 36-point axial clutch technology at the rear wheel. This system also has the advantage of reducing the effect of friction during freewheeling phases, to allow the small gains that make all the difference in a performance objective. Finally, a small detail that shows the exceptional quality of the whole, the graphics are not in the form of stickers but are printed directly on the rim using Zipp Impress technology. The weight of the wheel is thus reduced to a minimum, and its style is preserved! Incredibly powerful, these wheels are even stiffer than the 404 NSW, but also more technically and physically demanding. They will prove to be particularly well suited for a nervous driving style, with many relaunches.
