The Lucky Jack by DUKE is a very light and wide rim for cross country and marathon use. The rim provides not only an excellent lateral stiffness, but also a great tire support even when riding at a low air pressure resulting in a remarkably increased grip and comfort. The asymmetrical rim profile optimizes spoke angle to offer various advantages. The absorption of impact energy is improved by more than 20% compared to the previous model. The rims benefit from the SLS3 manufacturing process. This manufacturing process goes even further today as it is now made under dust-free laboratory and no longer requires sanding nor painting. SLS3 products have an excellent aesthetic appearance, right out of the mold. As they are no longer painted, the rims can not be scratched.
This type of rim is far stronger than the traditional clincher rim. Duke has used this technology with great success, on their rims since 2011
The bead of the tire is held in position irrespective of the tire pressure and the ground conditions, preventing any risk of the tire coming off its rim even when giving it full gas in the corners.
By offsetting, DUKE was able to increase the potential lateral wheel strength and its stability without adding weight. Rim drillings are off-center to improve bracing angles for a stronger, more rigid wheel.
A wider profile rim increases the comfort, for the rider, compared to a similar width tire mounted on a narrow "standard" rim because of the increased air volume in the tire.
These rims are 10% lighter than classic version, while maintaining exactly the same strength and stiffness. They manufactured in a sealed atmosphere and requires no retouching at the exit of the mold. No sanding or varnishing, the finish is exceptional!
