DUKE Rim 29" Lucky Jack Ultra SLS4 6Ters 30 UD-Carbon
Duke has succeeded in making the Lucky Jack even better than the SLS3 version. In doing so, they have once again pushed the seemingly technically possible limits. A 30 mm wide rim with a weight of only 284 g is a direct challenge to the competition.
How did the French achieve this? They took a closer look at the individual elements of the rim and searched for optimization possibilities. In particular, a new resin was used. This not only made it possible to reduce weight, but also to increase impact resistance. Similar to the SLS3 production process, no post-processing or painting is necessary after production.
In the Ultra version, material was also saved in non-critical areas in order to save further weight without compromising functionality.
The rim has an asymmetrical rim profile, which enables a more even spoke angle. This optimization of the spoke angle has a number of advantages. The spoke tension on both sides can be better aligned, which is beneficial to the durability of the spokes and the wheel as a whole. The normally direction-dependent lateral stiffness is also adjusted, making the wheel stiffer in itself.
Duke goes its own way with the "6Ters" concept. The cross-section of the rims is different on the front and rear wheels. At the front, the larger inner width provides more grip and stiffness, while at the rear the focus is on impact resistance and comfort.
The SLS4 6Ters 30 mm rim is intended for the front wheel and is the ideal combination with the 28 mm or 25 mm rim on the rear wheel.
