DUKE RIM CRAZY JACK SLS4
Carbon rim for All Mountain
JANTE DUKE CRAZY JACK SLS4
Pair of carbon wheels for All Mountain and Enduro use. Its large width optimizes the behavior of the tire and thus promotes the efficiency,
Comfort and grip thanks to a larger volume of air. It offers unrivaled lateral stiffness / weight ratio in its class and provides unusual sensations. Designed, developed and tested in France, The DUKE Crazy Jack in carbon has an ASYMMETRICAL profile (offset of 3 mm) which allows to increase the lateral stiffness of the wheel without gaining weight. The internal width between the hooks / sides is 32,5 mm. This gives more volume to the tires and improves efficiency, comfort and grip in turns.A wide rim also means that you can use finer, lighter tires while maintaining the comfort, softness and grip provided by a larger volume of air. Hookless design: the robustness of the rim is superior to that of a carbon rim with hooks. This technology has been used successfully on our rims since 2011. The height of the rim edge for 2015 is reduced by 1mm to further limit any risk of contact with the ground. Lateral stiffness improved by 40% compared to the previous version. Impact-resistant even on the most brittle ground: improved impact energy absorption of more than 50% compared to the previous model. Anti-burp system: the heel of the tire is held in position whatever its pressure, no risk of "unseating". Tubeless or inner tube.
In 2019, MTB rims profiles are differentiated as we do not ask the rims the same qualities while riding :
A front wheel must give grip, be light, stiff and handy.
A rear wheel must be more comfortable, tronger and offer more efficiency.
Thus the front and rear wheels have different profiles and lay-ups.
In collaboration with Rémy and Julien Absalon, the 6TERS front and rear profiles complement each other for a greater efficiency in the trails.
Many of you are aware of different needs because you are already using different section tires at front and rear wheel.
The Duke 6TERS* concept offers a wider front rim than the rear rim for more grip and stiffness. Its weight is optimized for robustness.
The rear profile is reworked with a reduced section, with a new carbon fiber layer to improve compliance and increase the impact resistance, the constraints being much more important on the back wheel.
SLS3 Factory Process ‘21
All our carbon MTB rims now benefit from the manufacturing process tested and approved by the 2018 Super Light Series, which offers gain in rim’s weight.
This manufacturing process goes even further today as it is now made under dust-free laboratory and no longer requires sanding nor painting.
SLS4 products have an excellent aesthetic appearance, right out of the mold.
As no longer painted, the rims can not be scratched.
Impact resistance is not left out, since it is also improved by 10%.
SLS4 rims are built from UD carbon fiber only.
Anti-Pinch
Rim’s sidewalls are thickened to prevent cut of tires during impacts.
