The profile of the Var 77 TCD rim was developed using the world first artificial intelligence driven process to offer the best aerodynamics when used with 25-28mm tires.
The external width of 30mm optimizes the airflow in combination with wider tires, while the internal width of 21mm ensures that the wider tires achieve a stable, round profile. The Var 77 rim profile achieves excellent aerodynamics in the real world conditions where the wind comes from different directions during your ride, not in a orderly manner as seen in wind tunnels. In fact the drag of Var 77 wheels falls in presence of cross winds
