In time trials and triathlon courses, every watt counts. Velo 82D is designed precisely for this: a high-profile carbon wheel, built for modern frames with disc brakes and optimized specifically for time trials, triathlon, and flat, high-speed courses. The 82 mm rim profile slices through the air at high speed, reducing aerodynamic drag and allowing you to maintain your pace and save energy during prolonged, intense efforts. The rim width of 21/31.5 mm, optimized for 25C to 30C tires, smooths airflow and reduces turbulence for a more stable ride. Inside, S&S ceramic bearings and lightweight Alpina Ultralight Aero steel spokes work together to minimize friction and improve responsiveness.
