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.

Technology

  • Hookless

    This technology has been successfully used on our MTB rims since 2011. It reduces rim weight. Strength is improved. The tire is slightly bigger. Carbon rims are simpler and more economical to manufacture.

  • VFP (Varnish Free Process)

    Since 2021, our carbon rims benefit from a unique finish: incomparable brilliance and reflections thanks to a new process called VFP without varnish. This, also and above all, makes them more environmentally friendly by drastically reducing VOC and carbon dust emissions compared with a traditional rim. Without varnish, the rim is also harder on the surface, and more resistant to scratches.

  • SLS4 (Super light series 4)

    The SLS4 series for mountain bikes is 10% lighter and more resistant than the sls3 version thanks to a completely new lay-up and a new resin which not only allow the same lateral stiffness to be maintained but also and above all to considerably improve comfort, vibration filtering and rim performance. The SLS4 is always manufactured in a sealed atmosphere and does not require any retouching when it comes out of the mould. No rework or varnish, the VFP gloss finish is ecological and exceptional!

  • 6Ters

    6TERS is a concept of MTB rims differentiated between front and rear: a front wheel must maximize grip (inner width +), handling (rotational weight -) and control (lateral stiffness -). A rear wheel must provide traction, comfort (vertical stiffness-), stability (lateral stiffness +), efficiency (inside width -) and be stronger (reinforcements). Developed in collaboration with Julien Absalon (five-time world champion).

  • AntiBurp

    Thanks to this antiburp, the tire bead is held in position at all low pressures and under all loads, so there's no risk of the bead sliding off the rim or losing pressure even when cornering hard. Two edges prevent the tire beads from sliding horizontally towards the inside of the rim. Even after a puncture, the tire stays in place on the rim

  • Anti-pinch

    Rim’s sidewalls are thickened to prevent cut of tires during impacts.

  • Tubeless

    Our Tubeless compatible rims (UST, Tubeless Ready and Notubes), only require some Duke rim tape and a Tubeless-ready valve. They can also be used in a classic clincher set up (tyre & inner tube).

  • Ultimate Comfort

    Thanks to the latest innovations and our research into composite material, we have been able to develop a unique process that maximizes compliance and absorbs vibrations. The result is an ultra-dynamic rim that filters out the imperfections of the terrain to be appreciated whatever the distance.

  • Offset

    Rim offset increases lateral stiffness and wheel stability without adding weight. The rim holes are off-center, improving the spokes brace angles. By better balancing the tensions between the two spoke sides, the wheel's durability is enhanced.

  • Width

    A wider rim provides greater comfort for the same tire cross-section, thanks to the greater volume of air in the tire. No need to inflate so much! The greater volume also enhances performance and grip. The bike's stability when cornering is also improved: a wider inner width reduces tire rolling under the rim under lateral loads. Using a wide rim improves comfort and control.

Crash replacement

We offer a crash replacement programme for carbon wheels. In case of accidents or heavy falls, violent shocks can damage your rim and make it impossible to use. With our Crash Replacement offer we offer you a service that allows you to replace your rim under special conditions: You get a 50 percent discount on the price of the rim (UD SLS carbon) 40 percent (3k Carbon), as well as the parts and the disassembly/reassembly. This offer is valid (for life) for an unlimited period of time for DUKE carbon rims and is transferable in the event of sale of the wheels to a third party.
