Do you need single wheels?
Advanced Aerodynamics:
Maximum aerodynamic efficiency for exceptional performance with seamless tire integration. Wide curved Rim minimizes air resistance, even with very wide tires. AIR+PLUS design for maximum bike control in side winds and gusts. Harnesses the wind for a significant aerodynamic advantage.
High Technology Construction:
The material of the future Carbon Fiber T1000 with Epoxy Graphene the lightest ever discovered. CeramicNitro2 Hubs with minimum friction and maximum durability. Hand centered withSAPIM Aero CX-RAY spokes and self-locking nipples with correct tension on each spoke.
Hub Nitro2 Ceramic Disc:
Ultra lightweight machined from 7075 aluminum with PAL-TECH 100% parallel, maximum precision ceramic coaxial bearings with larger diameter 28mm to withstand thousands of miles. 48 teeth with 4 powerful double pawls for minimum friction and maximum power transmission. The Nitro2 offers a unique weight to durability ratio.
With the optimized 2:1 radiusing we equalize the tension of the left and right spokes . Larger diameter in the right wing, we gain +2º more angle in the spokes to achieve more lateral stiffness.
" wheels spokes balanced spokes tension, greater rigidity, and increased durability."
Cannondale option Lefty
Have you signed up for Gravel with Lefty fork and want to change wheels? You should know that theLefty 8 or SuperMax Hub is not compatible.
In Progress we always have an option even with the old Lefty 1.0 Hub , now you can choose your wheels with 12mm axle or with Hub for Lefty fork buying the wheels individually.

AERO GRAVEL
Why are wheels important for Gravel?
Aerodynamic drag is one of the greatest forces of resistance a cyclist faces. Reducing drag helps conserve energy, especially over long distances.
Why do we think gravel wheels are the best choice?
If the profile is too low, you may lose speed. If it is too high, handling can become challenging in unpredictable conditions.
A Rim 50 mm or more is usually too heavy, which reduces responsiveness, since changes in pace and acceleration are constant in gravel.
For many cyclists, especially competitive ones, 40 mm has become the current sweet spot.
It is a well-balanced ride height that offers a real aerodynamic advantage without compromising confidence or control.
Our 40mm wheels and GX wheels remain the most balanced and versatile option for gravel.
In addition, its 28-mm internal width is ideal for fitting wide tires, offering maximum aerodynamic efficiency.
Everything else gets in the way and holds us back.
AIR+PLUS High speed technology
For example, when you're going 40km/h your wheels turns at twice the speed and side winds with strong gusts are capable of knocking you off the road.
With our new AIR PLUS aerodynamic design, Rim fully curved and with a 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.
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.
Tire Width Recommendation
OurAIR+PLUS Rims are very wide with 21mm inside and 28 or 30mm outside, which opens the Clincher wide enough for the tire and Rim walls to form a line without a step.
Clincher tires or tubulars from 23 or 25 to 28mm fit perfectly on ourAIR+PLUS Rims .
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.
23mm tire = 10,7 Watts
25mm tire = 12,1 Watts
28mm tire = 13,6 Watts
Expl: Wheels Aero with outer Rim width 24mm and 25mm tire = 16,8 Watts
