AERO
The outer shape of the rim is designed to optimize air flow around the rim and reduce turbulence. This helps to make the wheels more stable and faster. The rims can accommodate a wide range of tire widths, the rims are aerodynamically optimized for a narrower range.
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.
ASYMETRIQUE
By offsetting, we can increase the wheel’s lateral strength and its stability without adding weight. Rim drillings are off-centre to improve bracing angles for a stronger, more rigid wheel. Plus, with offsetting there’s a better balance between the drive and non-drive side spoke tensions and improved durability over the long-term.
DYNAMAL
Dynamal is 50% stronger than 6061-T6. Unlike standard alloy blends, Dynamal is a pure alloy, enriched with magnesium-silicon and combined with a confidential metal to harden it. Compared with traditional alloys, Dynamal offers a significant increase in stress and impact resistance, without any reduction in fatigue strength.
HOOKED
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.
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.
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.
POLYAXIAL-DRILLING
The orientation of the holes of a rim allows a perfect alignment of the nipples and spokes, which brings a better lifetime of the spokes, the rim and the wheel.
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).
SLR2 (Super light road series 2)
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!
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!
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.
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.
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.
