THE SUPER FAST COMBO WITH A BIG AERODYNAMIC ADVANTAGE FOR WINDY OR MOUNTAINOUS TRIATHLONS.
The A-Prime front wheel at only 10.7W (on average) the fastest disc wheel ever tested in the wind tunnel is reactive and very easy to control in gusty winds.
The Space on the rear, with only 7.4W air resistance it gives you the “turbo” sail effect on the flat and with its lightweight it doesn't slow you down on climbs. A perfect tire integration, giving a homogeneous structure that does not cut off the wind flow, even with 28mm tires. We use the latest technology in the manufacture of fiber, with the material of the future and the lightest one discovered so far, Graphene.

Built by hand with our best hubs, NITRO with ceramic bearings and ultra-strong SAPIM CX aerodynamic spokes.

LTD version comes with oil metallic effect logos and glossy finish.

A winning set offering high speed performance.

Rod Hub’s with 12mm thru axles.

As much as possible weight reduced. Not recommendable for riders whose weight is over 90 Kg. Lightweight wheels provide much better acceleration and climb.

A hub with Parallel Drilling technology ensures high precision 100% aligned bearing seats. PROGRESS hubs and bearings are designed for light weight, long lasting and best running performance.

Rear hub with a very strong three pawl ratchet mechanism. Engagement with 3 oversize pawls and steel ratchet with 24 teeth’s.

TLR Tubeless Ready We’re using most common rim bed design. Its advantage are excellent rolling resistance, fewer punctures and easy mounting tire.

PROGRESS cassette body option SRAM XD-R compatible made of CNC aluminum. Reinforced with 3 bearings to resist high loads.

These wheels are one of the fastest with best aerodynamic performance you can find. Check AIRBUS Wind Tunnel test in progress technology.

SAPIM CX aero spoke is the choice of champions and many teams at the Pro-Tour. Made in Belgium with an aerodynamic advantage and unbelievably high fatigue test results. We build them into our lighter wheels to achieve durable and long lasting wheels which don’t need to be re-trued. Each Progress Wheel, hub and rim is designed with perfect spoke angle to release extra stress.

High precision CERAMIC bearings with maximum precision and low friction that increase durability.

GRAPHENE is the world’s strongest and lightest material which offers a totally revolutionary rim technology. Graphene-enhanced full carbon rims are 50g lighter and 20% stiffer.

New Oversize hub body CNC made of AL7075 super lightweight. 3 cross straight pull for a 20% stiffer wheel and better aerodynamic performance. Super precis Japanese cartridge bearings with very low friction and bigger size for long lasting. 15mm CNC made Aluminium rear axle and free hub. Classical engagement with 3 oversize pawls and steel ratchet. New SRAM XD free hub with 3 bearings and Shimano with 2 bigger bearings, free hub Shimano and SRAM interchangeable without any modifications or adjustment. Road Nitro rear with 2:1 spoke lacing.

Crashed wheels! In case of bad luck, PROGRESS supports you by offering replacement rims for half the regular price during 1 year after purchase.

AIR+PLUS High speed technology with optimized aerodynamic efficiency and less drag. Lateral wind is no longer a problem anymore thanks to the new 28mm wide U-shaped carbon rim. This design allows the use of wider tires without negatively influence on the wind flow, more tire volume, lower rolling resistance and better handling in crosswinds condition. The AIR+PLUS is successfully worldwide race proven and wind tunnel tested. (Check AIRBUS GST results)

AIR+PLUS High speed technology

Why is aerodynamic so important to your wheels?
When you race 40km/h your wheels are spinning double 80km/h, hard cross winds are capable to throw you from the road.
With our wheels lateral wind is no longer a problem anymore thanks to the extra wide and latest U-shaped design.
This design allows the use of wider tires without negatively influence on the wind flow, more tire volume, lower rolling resistance and better handling in crosswinds condition. 23 to 28mm tires are seating totally integrated into the rim shape and do not offer extra friction.
This shape has high aerodynamic efficiency in accordance to latest scientific findings from wind tunnel testing’s.
Comparing to regular V-Shape rims we reduced drag and crosswind drag coefficient by more than 30%.

PAL-TECH

High precision aligned bearing seats with parallel drilling technology made by high-tech CNC 5-axis machine.
100% parallel to the axis of the spindle.
Less friction more speed and longer bearing life.

PSG (Perfect Spoke geometry)

Every Progress Wheel is designed for his specific operation purpose. Our choice of rim, hubs, spokes and lacing pattern isn’t just a coincidence.
We strengthen rims at every spoke hole on each rim we develop. The spoke hole and nipple seat is perfectly aligned with hub and spoke angle.
This creates a perfect spoke geometry which allows us to use high spoke tension by an evenly and equal tension distribution. Releasing excessive stress from spokes we get long-lasting and high performance on every wheel.
