The Venn 40 TCC SL 40mm rim brake carbon rim is a lightweight rim offering good balance between aerodynamics and weight

Super light rim brake rim with a graphene braking surface and 3D channels for better water management and superior braking in challenging conditions. This rim is available in two manufacturing methods: high performance hand layup and our 4th generation automated filament winding process.

Hand layup allows us to reinforce just the parts of the rim that are exposed to the highest loads and thus minimising the rim weight, while filament winding ensures that your rim has the highest structural performance that is achievable using carbon fiber – all fibers are laid up precisely and under constant tension.

The 4th generation 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 toughness and impact resistance.

CTL SL hand layup carefully positions the carbon fiber reinforcements only where needed

By reinforcing only the key sections of the rim we are able to manufacture very reliable but also very lightweight carbon rims.

The Venn 40 TCC carbon rim is 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.

We can assemble your set of carbon wheels using hubs of your choice.
