DUKE RIM WORLD RUNNER X 25

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.
