SLS4 (Super Light Series 4) | SLS models are 10% lighter than conventional rims with the same strength and stiffness, thanks to a proprietary manufacturing process and different types of carbon fibers and resins. In addition, SLS4 rims are manufactured in a closed atmosphere, so no finishing is required. Without sanding or painting, an exceptional finish is achieved in the process.
6TERS ("sisters") | To meet the different demands that act on the front and rear of a mountain bike, the 6TERS concept uses a differentiated design for front and rear wheels. While the rim intended for the front wheel should be correspondingly wider, a reduced cross-section is used for the rear wheel. While grip, low weight, stiffness and maneuverability are the key factors at the front, comfort, resistance and high-performance power transmission are the decisive parameters at the rear.
Heavy Duty (HD) Building Concept | To achieve high resistance, the Heavy Duty design combines a targeted selection of materials with optimum rim geometry. Thanks to the interaction of high-strength carbon or aluminum with the offset construction, DUKE HD rims absorb most shocks and impacts, making them perfect for any type of terrain.
DUKE Original Profile | In 2 words: Duke Technology. DUKE owns the manufacturing tools and processes for its alloy rims 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 that are the result of 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.
