THE COMBINATION WITH THE GREATEST AERODYNAMIC ADVANTAGE FOR WINDY OR HILLY TRIATHLONS.
Advanced Aerodynamics:
Maximum aerodynamic efficiency for exceptional performance. Rim wide curved minimizes air resistance, even with tires from 28mm. Air resistance of only 7.4 watts at 45 km/h on the Space model and only 10.7 watts at 45 km/h on the A-Prime, over a wind attack range of +/- 20 degrees. Design AIR+PLUS for maximum bike control in side winds and gusts. Harnesses the wind for significant aerodynamic advantage. Versatility in varied terrain.
High Technology Construction:
The material of the future Carbon Fiber with Epoxy Graphene the lightest ever discovered. Hubs Nitro ceramic with minimum fiction and maximum durability. Hand centered with SAPIM Aero CX-RAY spokes and self-locking nipples with correct tension on each spoke.
Bushing Nitro:
Ultra Lightweight machined 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 weight to durability ratio.

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 to offer maximum performance to 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, 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.
Tire Width Recommendation
Our Rims AIR+PLUS are very wide with outside width 28 to 30mm, which opens up the Clincher enough for the tire walls and Rim to form a line without a step. 23 or 25 tires or tubulars up to 28mm fit perfectly on 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
at a speed of 45km/h with different tires.
