DUKE rim 29" Crazy Jack SLS4 6Ters 30 UD carbon
Duke has managed to improve the Crazy Jack compared to the SLS3 version. In doing so, they have once again pushed the apparently technically possible limits. A 30mm wide rim weighing just 371g is a direct challenge to the competition.
How did the French do this? They took a closer look at the individual elements of the rim and looked for optimization options. In particular, a new resin was used. This not only made it possible to slim down, but also to increase impact resistance at the same time. Similar to the SLS3 production process, post-processing or painting is not necessary here either.
The rim flange is hookless and reinforced. This avoids damage in the event of punctures. In addition, the anti-burp technology prevents the tire from slipping or jumping off the rim and thus possible air loss.
The rim has an asymmetrical rim profile, which allows a more even angle of the spokes. This optimization of the spoke angle brings with it a multitude of advantages. The spoke tension on both sides can be better adjusted to each other, which is beneficial to the durability of the spokes and the entire wheel. The lateral stiffness, which is normally directional, is also adjusted so that the impeller itself becomes stiffer.
With the "6Ters" concept, Duke goes its own way. The cross-section of the rims is different on the front and rear wheel. At the front, the larger inner width allows for more grip and rigidity, while at the rear, emphasis was placed on impact resistance and comfort.
The SLS4 6Ters 30mm rim is intended for the rear wheel and represents the ideal combination with the 33mm on the front wheel.
