Do you need single wheels?
Graphene is the material of the future and the lightest material discovered to date.
With the GPX we introduce a lightweight wheels MTB for Rally and Marathon ultra with a width of Rim inside of 30mm.
Manufactured with Graphene and the best fiber of Carbon (Toray), which is 11 times stiffer than the hardest aluminum known, if we add an extra width of the Rim we achieve the best ratio between stiffness and lightness.
All this together with the newNexo Z1 Ratchet Hub , more oversized, with ceramic bearings of maximum precision and minimum friction. Together with theSapim CX-Ray Straight Pull spokes , it gives these wheels superior lateral stiffness that transforms all your efforts into greater speed.

PAL-TECH
Thanks to PAL TECH technology, we ensure 100% parallel bearings for maximum performance of your wheels.
PROGRESS Hubs are designed for minimum weight and maximum durability.
PSG (Perfect Spoke geometry)
At Progress we design each wheel for its appropriate use.
The choice of spokes, Hub design, Rim and centering are not left to chance.
In everyPROGRESS Rim we add extra reinforcement material in the area of the spokes and we specify the seat angle of the nipples in perfect geometry with the angle of the spokes on the Hub. This allows us to work with the optimal tension and get the maximum performance out of each wheel. In addition, we avoid spokes breakage and provide a long-lasting wheel .
ORTF (Optimized Rim & Tire fit)
At PROGRESS we only offer Rims designed specifically for each type of wheel and use.
Only the perfect size, both inside and outside, allows you to install the perfect tire so that it is properly integrated into the Rim.
A wide Rim offers more stability and minimizes undercutting. It allows the tire to maintain a larger contact patch making it more stable against lateral forces.
On technical climbs it provides greater traction and on descents it improves cornering.
