Progress Air Tubular road wheel set

The most versatile carbon wheel set for climbing and grand rides very efficiently aero performance on the flats upward with superior stiffness and weight of only 1.140 grams‐tubular.

Graphene is the world’s strongest and lightest material which offers a totally revolutionary rim technology.

Nitro Ceramic hubs with PAL-TECH technology.


Features:

- Sram: PROGRESS cassette body option SRAM XD-R compatible made of CNC aluminum. Reinforced with 3 bearings to resist high loads.
- Rear hub with a very strong three pawl ratchet mechanism. Engagement with 3 oversize pawls and steel ratchet with 24 teeth’s.
- Pal-tech: 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.
TLR Tubeless Ready We’re using most common rim bed design. Its advantage are excellent rolling resistance, fewer punctures and easy mounting tire.
Tubeless: 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.
- Spokes: Crashed wheels. In case of bad luck, PROGRESS supports you by offering replacement rims for half the regular.
- Diamond: DPL Brake Surface, Diamond Polishing Treatment. We are using advanced machinery & Diamond Polishing Treatment (DPL) for brake surface, allows the brake pad to work directly on 3K woven carbon fibers. This new process eliminates ´´run-in´´ periods, improves braking performance in wet and dry weather conditions, and creates much better braking performance.
- Nitro: High precision CERAMIC bearings with maximum precision and low friction that increase durability.
- 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.
- 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.
- E.C.S Extra Carbon Strip. Provide extra stiffness on spoke holes. Ensure the rims will not be damaged if a spoke breaks and allows a better spoke tension. Our rims are capable of withstanding a spoke force of 300kg.
- C.S.T Carbon stabilizer.The incredibly strong Cyanacrylat composite center is the backbone of our brake walls.Makes our clincher rims 90% stronger than regular carbon rims.
- Freewheel: PROGRESS cassettes bodies can be easily removed and replaced with no extra adjustments. Switch quickly between Shimano, Campagnolo, or SRAM cassettes.
- 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.
As much as possible weight reduced. Not recommendable for riders whose weight is over 90 Kg. Lightweight wheels provide much better acceleration and climb.
- Hand Built: Extremely durable hand built wheel. High durability and high precision.

Technology:

AIR+PLUS High speed technology:
- 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.

Tire Width Recommendation:
- For maximum aerodynamic efficiency on your wheels we recommend that the width of the tire does not exceed the outer width of the rim. Our AIR + PLUS rims are very wide with 27 to 30mm, opening the tire enough so that the tire and rim walls form a seamless line.

- Clincher or tubular tires from 23mm up to 28mm are perfectly integrated into our AIR + PLUS rims.
As a reference we have tested the air resistance of the APRIME in the wind tunnel with
a speed of 45km/h with different tires.

- 23mm tire = air resistance by 45Km/h = 10,7 WATT
- 25mm tire = air resistance by 45Km/h = 12,1 WATT
- 28mm tire = air resistance by 45Km/h = 13,6 WATT
We measured 16,8 Watt using regular aero wheels with 24mm rims and 25mm tires
