DUKE CRAZY JACK WHEELSET RF (reinforced)
Pair of carbon wheels for All Mountain and Enduro use. Its large width optimizes the behavior of the tire and thus promotes the efficiency, Comfort and grip thanks to a larger volume of air. It offers unrivaled lateral stiffness / weight ratio in its class and provides unusual sensations. Designed, developed and tested in France, The DUKE Crazy 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 / sides is 28.5 mm. This gives more volume to the tires and improves efficiency, comfort and grip in turns.A wide rim also means that you can use finer, lighter tires while maintaining the comfort, softness and grip provided by a larger volume of air. Hookless design: the robustness of the rim is superior to that of a carbon rim with hooks. This technology has been used successfully on our rims since 2011.  The height of the rim edge for 2015 is reduced by 1mm to further limit any risk of contact with the ground. Lateral stiffness improved by 40% compared to the previous version.  Impact-resistant even on the most brittle ground: improved impact energy absorption of more than 50% compared to the previous model.  Anti-burp system: the heel of the tire is held in position whatever its pressure, no risk of "unseating". Tubeless or inner tube.. En savoir plus.
