The ultimate weapon for demanding races

The Lucky Jack SLS ULTRA is the lightest 29″ carbon rim ever designed by DUKE Racing wheels.
By exploiting the SLS technology it was possible to lower the weight of the Lucky jack SLS Ultra to 275g while maintaining the same characteristics as the previous version.
The same strength and rigidity that made the reputation of Lucky Jack. Light, rigid, resistant and ultra nervous its will face all situations. The Hookless system makes it more resistant and offers better tire strength, allowing inflation at low pressure.

Technologies & Features

Hookless Rim

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

Burp-Free System

The bead of the tyre is held in position irrespective of the tyre pressure and the ground conditions, preventing any risk of the tyre coming off its rim even when giving it full gas in the corners.

Asymmetric Profile

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.

Wide inner rim

A wider profile rim increases the comfort, for the rider, compared to a similar width tyre mounted on a narrow "standard" rim because of the increased air volume in the tyre.

Tubeless Ready

The Tubeless compatible rims by Duke (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).

SLS (Super Light Series)

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!
