U4

The new design is not only an aesthetic improvement, although the appearance is so outstanding and eye-catching, it still can't hide the strong performance!Over the years ,both in appearance and performance, it has maintained its own unique style,and of course the new Ultrapex U4 also inherits a good pedigree! In order to present the best rotation and acceleration performance,on a sufficiently rigid and strong basis, the peripheral weight is reduced as much as possible and most of the weight is distributed near the center. From the appearance, it is not difficult to find that the extremely streamlined and lightweight rims, coupled with the wild and exaggerated hubs, It has always been to achieve the design principle of light on the outside and heavy on the inside. Light weighting has always been fascinating, but we're more focused on achieving better acceleration and rotational performance! The new generation of D3 V.P.M carbon fiber spokes uses 40 tons of fibers with a higher stiffness and strength than before. This allows the lightweight, flattened spokes to perform better than ever before.
