The essential tool for achieving peak performance in time trials or triathlons. Perhaps the lightest on the market, highly efficient, allowing you to save significant watts on flat terrain and climbs. Tested by some of the world's fastest professionals, such as Antonio Benito (2024 Long Distance Triathlon World Champion). H.E.A. High Aerodynamic Efficiency. Through exhaustive wind tunnel testing we have achieved a highly efficient aerodynamic design. An ultra-lightweight, double-walled Toray carbon construction that offers the same lateral stiffness as its much heavier rivals. The A-990 has exceptional performance and weight, and its real-time gain is impressive. The Tubeless rim with a 21mm internal width creates a perfect integration between the rim and the tire. The inner hub is machined from aluminum with Coax precision bearings and 6 pawls with 72 teeth. The wind passes unimpeded, the sail effect pushes you forward, and on climbs there is nothing to hold you back.
