Venn Var 77 TCC clincher rim brake bike DT Swiss 350 carbon wheels

The profile of the Var 77 TCC rim brake bicycle 77mm carbon wheels 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 77mm rim profile achieves excellent aerodynamics in the real world conditions where the wind comes from different directions during your ironman, or triathlon ride, not in a orderly manner as seen in wind tunnels. In fact the drag of Venn Var 77 carbon wheels falls in presence of cross winds

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 77 TCC 77mm 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.

The rim width also means that the wheels 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 deep section carbon wheels that can be used in any conditions.

The DT Swiss 350 straight pull rim brake hubs are a reliable and long lasting choice for both training and racing.
