Venn Var 45 TCD filament wound tubeless clincher disc 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 temperature (Tg), 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 TCD 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. In fact the rim profile offers better aerodynamic performance than many 50mm profile wheels in the market.

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.
