Descrizione
The perfect wheels for everyday ridewith an incredible price-quality ratio.
A set of full carbon wheels, the most versatile to train and compete at a very affordable price. Now with the new wider AIR+PLUS rims in UD carbon with U-Shape profile we have achieved a significant improvement in aerodynamics.
Vektor Disc hub with high precision bearings with a larger diameter to offer maximum durability and less friction.
In addition, the 4 pawls offer a smoothness and sound that acclaims speed.
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%.
PSG (Perfect Spoke geometry)
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)
