Filament wound full carbon tubeless, or clincher rim, 50.7mm profile. Disc brake.
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 Var 507 rims are designed specifically for enhanced aerodynamic performance with wide tires.
The Venn Var 507 TCC disc specific rims are 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 handles exceptionally well and achieves optimal aerodynamic performance with tires that inflate to 25-26mm width.
High resolution 3D transient CFD simulations were used to develop the advanced Venn 507 profile. The end result are rims that can be ridden in any conditions as they do not generate torque and thus do not affect handling in cross winds, or even heavy traffic conditions.
