The Venn Var 507 TCC road bike rim brake carbon rim is a result of our extensive experience with aerodynamics. The goal was to deliver a rim shape that is not only aerodynamic, but exceptionally stable in crosswinds.

What is the point of a wheel being aerodynamic if it is too scary to use as soon as there is a little bit of cross wind, or even in city traffic? The Venn Var 507 TCC carbon rim allows wheels to handle exceptionally well and achieve optimal aerodynamic performance with tires that inflate to 25-26mm width.

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 507 TCC carbon 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.
