The profile of the Var 37 TCD road disc brake rim was developed to offer the best aerodynamics when used with 25-28mm tires and is part of the same family as the exceptional Venn Var 507 rim series.
The external width of 28mm 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 rim width also means that the rims are laterally very stiff while the filament winding process ensures that the rims remain vertically compliant due to the 45 degree fiber layup bias. The advanced CFD developed profile of the Venn Var 37 TCD rims ensures that their aerodynamic performance exceeds that of any rim in a similar category.
