Latest DUKE Rim 29″ Crazy Jack SLS3 6Ters 28 UD-Carbon | Rear Wheel

DUKE rim 29″ Crazy Jack SLS3 6Ters 28 UD carbon | rear wheel

The Crazy Jack SLS3 6Ters rims are the sharpest weapon for all-mountain riders and e-bikers.

Thanks to the French manufacturer’s SLS3 manufacturing process, the weight of the Crazy Jack 6Ters could be reduced to 385 grams. In addition to small material savings in some places, 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 SLS2 production process, post-processing or painting is not necessary here either. Visually and haptically, but also in terms of technical data, this rim need not fear comparison with higher-priced products in view of the relatively low price. With an inner width of 27 millimeters, the rim also offers wide tires a perfect support width, which makes it possible to keep tire pressure low. The grip level of the tire increases significantly as a result.

The rim has an asymmetrical rim profile, which results in a more even angle of attack for 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 wheel appears stiffer in itself.

With the “6Ters” concept, Duke goes its own way. The cross-section of the rims is different on the front and rear wheels. 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 Crazy Jack 6Ters with an inner width of 27 millimeters is intended for the rear wheel and, in combination with the 30 millimeter rim on the front wheel, represents the ideal combination.
