Winners of multiple awards

Our filament wound rim range won several of the highest honours in the bicycle and technology industry with filament winding being recognized as the most interesting carbon rim manufacturing technology in the world.

Manufacturing process

In filament winding a continuous tow of fibers is passed through a bath of resin and wound onto a revolving mandrel by traversing longitudinally along the axis of the rotating mandrel.

This results in optimal, continuous fiber placement under tension. The benefits - higher manufacturing uniformity, better performance and greater durability.

Key Benefits of Filament Winding over Manual Layup



Better quality and batch uniformity

Because filament winding is a machine managed process there are no random layup errors. Uncontrolled layup errors are one of the biggest drawbacks of the manual layup process. This leads to higher accuracy and precision and further contributes to our lower manufacturing costs.

The best method for manufacture of CFRP

Filament winding is theoretically the best method for manufacturing carbon fiber reinforced plastics (CFRP) as all fibers are placed under constant tension, in a single plane (cf. weaving which crimps the fibers) and in an optimal geometry that has no sharp bends or kinks. This results in the highest possible strength to weight and stiffness to weight ratios.

45 degree fiber bias

Our current winding pattern employs a +45/-45 degree winding bias which results in our rims and wheels having very high lateral stiffness (side to side), but lower than average radial stiffness (up and down). This results in wheels built with our filament wound rims being very stiff and responsive to acceleration, while enhancing road holding and lowering the occurrence of tire pinch flats or rim damage due to impact.

Unique

We are the only manufacturer in the world that offers filament wound rims. Thus, besides the performance and cost benefits that our technology offers, you also get a product that is distinct from every generic carbon fiber rim that is available in the market.


Filament Wound Rim Product Range

# Venn Rev 35 TCC

Filament wound tubeless and clincher tire compatible 35mm profile rims for rim brake bicycles

# Venn Rev 35 TCD

Filament wound tubeless and clincher tire compatible 35mm profile rims for disc brake bicycles

# Venn Rev 35 TUC

Wind tunnel tested aerodynamics

Venn Rev 35 rim series is the only OEM rim with wind tunnel data. You can be confident that our rim does not just look aerodynamic, but that it actually is aerodynamic. The results show that the Venn Rev 35 rims compare very well to much deeper profile rims while offering superior handling in cross winds and lower weight.
