THE FASTEST WHEELS IN THE WIND TUNNEL FOR DISC BRAKES
After many hours spent in design and wind tunnels we have done it. The fastest 38 disc brake wheels ever tested in a wind tunnel. A most versatile set for mountain and flat with exceptional performance and weight feather.
Advanced Aerodynamics:
Maximum aerodynamic efficiency for exceptional performance. Rim wide curved minimizes air resistance, even with tires from 28mm. Air resistance of only 12.1 watts at 45 km/h in a wind attack range of +/- 20 degrees. AIR+PLUS design for maximum bike control in side winds and gusts. Harnesses the wind for significant aerodynamic advantage.
High Technology Construction:
The material of the future Carbon T1000 Fiber with Epoxy Graphene the lightest ever discovered. Hubs Nitro ceramic with minimum friction and maximum durability. Hand centered with SAPIM Aero CX-RAY spokes and self-locking nipples with correct tension on each spoke.
Hub Nitro:
Ultra light machined from 7075 aluminum with PAL-TECH 100% parallel bearings, maximum precision ceramic coaxial bearings with larger diameter 28mm to withstand thousands of kilometers. 3 pawls with 24 and optional 36 teeth provide minimum friction and firm engagement. The Nitro offers a unique ratio between weight and durability.

AIR+PLUS High speed technology
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.
PAL-TECH
Thanks to PAL TECH technology, we ensure 100% parallel bearings for maximum performance of your wheels.
The Hubs PROGRESS 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, the design of the Hub, the Rim and the centering are not left to chance.
For each Rim PROGRESS we add extra reinforcement material in the spoke area and specify the angle of the nipple seat in perfect geometry with the spoke angle at 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 durable wheel.
Tire Width Recommendation
Our Rims AIR+PLUS are very wide with 21 mm inside and 28 or 30mm outside, which opens up the Clincher enough for the tire walls and Rim to form a line without a step.
Tires or tubulars of 23 or 25 up to 28mm fit perfectly on our Rims AIR+PLUS .
As a reference, we have tested in the wind tunnel the air resistance of APRIME tires at a speed of 45km/h with different
speed of 45km/h with different tires.
23mm tire = 10,7 Watts
25mm tire = 12.1 Watts
Tire of 28mm = 13,6 Watts
Expl: Aero wheels with Rim outside width 24mm and 25mm tire = 16,8 Watts
