LIGHTNESS - DURABILITY - MANOEUVRABILITY - RIM WIDTH - TUBELESS COMPATIBILITY
The DUKE World Runner Carbon has a profile height of 38mm. Inner width 25mm: This gives more volume to the tires and thus improves efficiency, Comfort and grip in turns. A wide rim also means being able to use the finer and lighter tires while maintaining comfort, The softness and grip provided by a larger volume of air. More info
SLR2* Factory Process
All our carbon MTB rims now benefit from the manufacturing process tested and approved by the Super Light Road 2, which offers a 15% 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.
SLR2 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 20%.
SLR2 rims are built from UD carbon fiber only.

Technology
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.
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).
The SLR2 series for Road and Gravel is 15% lighter and more resistant than the sls version thanks to a completely new lay-up and a new resin which not only allow the same lateral rigidity to be maintained but also and above all to considerably improve the comfort, vibration filtering and rim performance. The SLR2 is 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!
We keep the hooks on all our gravel and road rims. As the pressures used are higher than in mountain bikes, the risk of the tire sliding off the rim is too high with hookless rims. What's more, for a given inside width, rims with hooks have a wider outer width than rims without hooks, which enhances the aerodynamics of the rim/tire assembly.
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.
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.
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.
