Se que puedo confiar siempre en mis ruedas Progress Air pues me dan todas las prestaciones que necesito, tanto en entrenamiento como en competición.
En los sinuosos circuitos de ciclismo de las ITU World Series, donde siempre hay que ir a tope y estar preparado para aceleraciones y arrancadas continuas, se nota increíblemente la rigidez y rodadura de mis ruedas Progress. Me quedo impresionado con lo fácil que se aceleran en los complicados giros de 180 grado y una vez lanzadas, ver como se mantienen a una velocidad endiablada y que me permiten estar siempre en cabeza.

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%.

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.
