PROGRESS Rear Wheel for Clincher A-7D DISC 12X142 SHIMANO HG PGRUA7DDCT4HGNG

The winning wheel for time trials and triathlons. Not only does it allow you to save many watts, but the real-time gain is impressive. Over 90 km flat 4 min and more.
H.E.A. High Aerodynamic Efficiency.
After many hours in the wind tunnel we have achieved a highly efficient aerodynamic design (H.E.A. high aerodynamic efficiency)
The A-7D has exceptional performance, offering only 5.9 watts of air resistance at 45km/h in a wind attack range between +/- 20 degrees.
An ultra-light 12K carbon construction reinforced on the inside. The inner hub machined from aluminum with ceramic bearings.
The concave design makes better use of the wind, increasing the sail effect and speed, 0 turbulence (drag) and the wind passes without obstacles.
With this design we also reinforce the lateral rigidity by 20%.
This year we added a carbon cap with Velcro closure to cover the valve and for 2024 we increased the width.
