DUKE RIM MARY JACK
Made for All Mountain. The Hookless side, coupled with its width of 28mm increase its rigidity and its resistance to the impacts. The DUKE Mary Jack in carbon has an ASYMMETRICAL profile (offset of 3 mm) which allows to increase the lateral stiffness of the wheel without gaining weight. The internal width between the hooks / large walls is 40 mm. This gives more volume to the tires and improves efficiency, comfort and grip in turns. A wide rim also means being able to use thinner and lighter tires while maintaining comfort, The softness and grip provided by a larger volume of air. Hookless sides: the robustness of the rim is superior compared to a carbon rim with hooks. This technology has been used successfully on our rims since 2011. Anti-burp system: the heel of the tire is held in position whatever its pressure, no risk of "out rim". Tubeless or inner tube. En savoir plus.
