Technology
-
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
-
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).
-
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.
-
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.
-
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.
-
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.
Sapim Spokes
Sapim is THE brand of spokes, made in Belgium since 1918. Several models of spokes are available, within the limits of compatibility with the practice and the chosen rim:- Sapim CX-Ray: flat spoke, very light, durable, aero and very dynamic (309g / 64 pcs / 292mm)
- Sapim CX-Sprint: Flat spoke identical to the CX-Ray but thicker for even more rigidity (373g / 64pcs / 292mm)
- Sapim D-Light: round spoke, light and durable, with a 1.65mm diameter central part, good value for money (344g / 64 pcs / 292mm)
