PROGRESS A-7D CL Disc Tubeless LTD road wheel set

The winning combination limited edition for time trials and triathlon. Not only does it allow you to save a lot of watts but the real time gain is impressive. Over 90Km flat 4min and more. After many hours in the wind tunnel we have achieved a highly aerodynamic efficiency (H.E.A. high aerodynamic efficiency) aerodynamic design. The A-7D has exceptional performance, offering only 5.9 watts air resistance at 45km/h in a wind attack range between +/- 20 degrees. A 12K carbon construction ultra lightweight and reinforced inside. Machined aluminum inner hub with ceramic bearings. The concave design makes better use of the wind by increasing the sail effect and speed, 0 turbulence (drag) and the wind passes unhindered. This design also increases lateral stiffness by 20%. This year we added a carbon cap with Velcro closure to cover the valve.The A-7F is a fully aerodynamic 3-spoke carbon front wheel that does not produce turbulence and the wind passes unhindered. An extremely stiff construction with Rim fully curved 70mm profile offers good control in side wind. The A-7F has exceptional performance, offering only 6.6 watts air resistance at 45km/h in a wind attack range between +/- 20 degrees. The inner hub is machined from aluminum with ceramic bearings.
