JANTE DUKE LUCKY JACK ULTRA SLS3
The Lucky Jack ultra SLS2 by DUKE is a very light and broad rim for cross country and marathon use. Weighing 265g (+/-15g) the weight is surprisingly low. Great value have the dimensions of the rim. With 24,5 / 28 or 30 mm inside the rim provides not only an excellent lateral stiffness, but also the tire optimum support width. Also at low air pressure, the driver (in) no spongy driving feel, as the tires can snap off bad side. Grip and comfort of the tire increase remarkably! Of course, the rim can be driven with sealing Tubeless "milk". The wheels are provided with an asymmetrical rim profile, which requires a more uniform pitch angle of the spokes. This optimization of the spoke angle brings a number of advantages. The spoke tension on both sides can be better matched to one another, what is the shelf life of the spokes and the entire impeller conducive. The normally directional lateral stiffness is also adjusted so that the wheel appear rigid in itself. The height of the rim edge for is reduced by 1mm to further limit any risk of contact with the ground. Lateral stiffness improved by 40% compared to the previous version. Resistant to impacts even on the most brittle ground: For all LUCKY JACK SLS2 technology version the absorption of impact energy improved by 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". For the rim a Rider weight limit (incl. Clothing and luggage) applies
Technology
-
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.
-
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.
-
SLS3 Super light serie 3
The SLS3 series for MTB is 10% lighter and stronger than the sls2 version, while maintaining exactly the same stiffness. This gain is due to a new material.
In addition to these improved characteristics, the SLS3 is also manufactured under a sealed atmosphere and does not require any retouching when it comes out of the mould. No sanding or varnishing, the glossy finish is exceptional! -
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.
