DUKE Original Profile | In 2 words: Duke Technology. DUKE owns the manufacturing tools and processes for its alloy wheels and the molds for its carbon models. This allows them to offer you some of the most technically advanced rims with a wider, offset profile, the result of many years of experience.

Asymmetric Profile (Offset) | The offset allows to increase the lateral stiffness and the stability of the wheel without adding weight. The rim holes are off-centered to optimize the stiffening angles and make the wheel stronger and stiffer. In addition, an offset improves the balance between the spoke tension on the drive side and the opposite side, as well as durability in the long term.

Antiburp System | The "Burp-Free" system keeps the tire bead securely in position regardless of tire pressure and ground conditions. This prevents the tire from coming off the rim even at maximum speed. Since lateral indentation of the tire towards the center of the rim is prevented, there is no risk of sudden air loss even when cornering.

* Hookless rims are specially designed for use with tubeless tires. It is also possible to ride a tubeless-specific tire with a tube. However, the use of classic clincher or folding tires is not recommended.
