AIR

Why are aerodynamics so important for your wheels?
For example, when you are going 40km/h your wheels spin at twice the speed and side winds with strong gusts are capable of throwing you off the road.
With our new AIR PLUS aerodynamic design, Rim fully curved and with maximum width of 28mm, side wind is no longer a problem. It also allows the use of wide tires without negatively influencing the wind flow.

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.

Each type of wheel has different requirements.
At Progress we design each wheel for its appropriate use.
The choice of spokes, hub design, Rim and 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.

For maximum aerodynamic efficiency in your wheels we recommend that the tire width does not exceed the outside width of the Rim.
Our Rims AIR+PLUS are very wide with outside 27 to 30mm, which opens up the Clincher enough for the tire walls and Rim to form a line without a step.

Tubular or tubular tires of 23 or 25 up to 28mm are perfectly integrated in our Rims AIR+PLUS .

As a reference we have tested in the wind tunnel the air resistance of the APRIME with a speed of 45km/h with different tires.
speed of 45km/h with different tires.

23mm tire = 10.7 Watts
25mm Tire = 12.1 Watts
Tire of 28mm = 13,6 Watts
Ex: Aero wheels with Rim outside width 24mm and 25mm tire = 16,8 Watts
