PAL-TECH

With our latest generation 5-axis CNC machines, we guarantee absolute precision in all machining operations.
Thanks to PAL TECH technology, we ensure 100% parallel bearings to offer maximum performance to your wheels.
The Hubs PROGRESS are designed for minimum weight and maximum durability.

PSG (Perfect Spoke geometry)

Each type of wheel has different requirements.
At Progress we design each wheel for its appropriate use.
The choice of spokes, the hub design, the Rim and the centering are not left to chance.
On each Rim PROGRESS we add extra reinforcement material in the spoke area and we specify the seat angle of the nipples in perfect geometry with the spoke angle on the hub. This allows us to work with the optimum tension and get the maximum performance out of each wheel. In addition, we avoid spoke breakage and provide a long-lasting wheel.

ORTF (Optimized Rim & Tire fit)

Each modality needs its specific Rim along with its specific tire.
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 to fit properly on 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.

Tire Width Recommendation

The inner dimension of the Rim is what gives us the width we should choose for our tire.
Here is our recommendation for MTB wheels.
