Notably, bottom bracket stiffness has been enhanced by 7.5%, ensuring responsive power transfer. (capovelo.com)
Wilier’s collaboration with Elite has resulted in a proprietary “Aerokit” system, integrating custom aero bottles and cages that function as aerodynamic spoilers, streamlining airflow around the frame. This innovation contributes to a 13.6% reduction in drag at 50 km/h, translating to a 14.15-watt power saving at 40 km/h. (bikeradar.com)
