AR:ONE - Aero/All-round

Through advanced carbon engineering and optimized layup techniques, the AR:ONE’s head tube, bottom bracket, and down tube deliver exceptional lateral and torsional stiffness—maximizing pedaling efficiency and ensuring that every watt is transferred directly to the road. Yet true frame design extends beyond pure power transfer. Alongside drivetrain efficiency, a performance road frame must account for variable road surfaces and rider comfort. To achieve this balance, our engineers have integrated nanotechnology with compliant fiber layers, increasing load capacity and impact resistance while attenuating high-frequency road vibrations. The result is a frameset that combines race-level responsiveness with all-day ride quality.
