- INTRODUCTION -

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 4 disc brake (U4DB) 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. Lightweighting 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.

THE OVER SIZE REAR HUB

Shorter spoke length and optimized spoke angles,resulting in lower deformation and more sensitive acceleration.

THE FRONT HUB

The front hub has been redesigned, now it is stronger than before. That will be ensured by the well known TPI bearing technology.Increasing the smoothness and durability.More ideal weight configuration in front wheel to maintain the best wheel weight .

THE SPOKE PATTERN

The two to one spoke pattern both on front and rear wheel.That makes wheels very strong and high stiffness.

THE RIM REINFORCEMENT

The optimized carbon lay-up technology makes our rims stronger and lighter!

THE AUTOMATIC ADJUSTMENT

The bowl type stainless washer reduces localized stresses.Also act as a ball joint and automatically adjustment to prevent the risk of spoke failure or rim cracking.

VACUUM PRESS MOLDING

The optimized carbon lay-up and vacuum press molding technology to make our carbon spokes stronger and reliable!

THE PATENTED SPOKE STRUCTURE

In addition to the use of high-strength structural adhesives, The rough surface of carbon fiber and the screw-like structure (barb) on the 7075 aluminum alloy parts make the spoke structure more durable.
