Artificial intelligence designed parallel filament wound tubeless clincher carbon rim. 77mm profile, rim brake compatible.
The profile of the Var 77 TCC deep section rim brake bike 77mm carbon rim 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 carbon 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 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 rims 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 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.

The 77mm carbon rim has proved to be quite useful and effective for me. I am a triathlete and cycling is my stronger event. Feeling faster during a difficult race is immensely helpful.

I have discovered over time that the Venn Var 77 TCC rim has extremely good handling aerodynamics. With these rims, you have a higher probability of maintaining your aero position while riding in windy conditions.

Matching the hype isn’t something that bicycle parts are known for but in this case, the Venn Var 77 TCC deep section carbon rim delivered on the hype. It does in fact handle as well as shallow rims in strong winds, and of course my times are a lot better. Great product
