Venn Var 45 TCC filament wound tubeless clincher rim brake carbon rim

VAR filament winding process utilises slit tape towpreg to accurately lay up the carbon fiber in an automated, computer controlled process. The use of preimpregnated carbon fiber tape allows us to use the latest resins that offer the optimal blend of high glass transition (Tg) temperature exceeding 240° C in testing , toughness and impact resistance. Var rims can therefore be used in challenging conditions where extended braking periods are expected.

The profile of the Var 45 TCC rim was developed 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 resulting aerodynamic performance exceeds that of generic 50mm+ rim based wheels in some conditions while offering superior handling.

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 combination of these features results in very fast, safe handling wheels that can be used in any conditions.
