Venn Var 45 TCC UE filament wound tubeless clincher rim brake bike carbon wheels

The profile of the Var 45 TCC rim brake bicycle 45mm carbon wheels was developed to offer the best aerodynamics when used with 25-28mm tires.

The external width of 30mm (28mm at the brake track) 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 of the Venn Var 45 TCC carbon wheels exceeds that of generic 50mm carbon 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 carbon wheels that can be used in any conditions.

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 Venn Var 45 TCC 45mm carbon wheels are compatible with clincher, or tubeless tires that when used with a sealant virtually eliminate the inconvenience of having a flat tire away from home, or during a race.

Venn Rea db hubs feature a cold forged, CNC machine hub shell with a low drag 24 pawl engagement freehub rolling on Enduro bearings that feature dual lip seals to keep the water and dirt out, and grease in ensuring better performance even in bad weather.
