Est. 2008 · filament winding pioneered 2015
Every number on this page is measured, not marketed.
We made the first filament wound bicycle rims, and every Venn rim model has to pass our impact test before it goes on sale. When a figure matters to you, it links to the process and the test data that produced it.

The range
18 wheelsets · all tubeless-ready · 5-yr rim warrantyS Steel spokes
Bladed steel spokes that any bike shop can true or replace, on Venn ratchet hubs. The lowest price on a Venn rim.
C Carbon spokes
Carbon aero blade spokes on hubs with ceramic bearings. The lightest, stiffest road and gravel sets.
HE1 Helix-01 hub
Venn's own Helix-01 hub with 72-tooth helical engagement, on Sapim CX-Ray steel spokes. A hub only Venn has.
Weights are ±30 g. Disc road & gravel freehub: Shimano HG / SRAM XDR / Campagnolo N3W. Rim brake: Shimano HG 11s.
Four steps. One specification.
The footage below shows the four steps every Venn wheelset goes through: winding, molding, inspection and building.
Filament winding
Computer-controlled winding lays 1k tape, 1,000 fibers each, exactly where the laminate design demands.
Precision molding
A PLC controlled molding process using high tolerance molds with a specially treated surface, prepared in a clean room environment to eliminate surface and layup imperfections.
Inspection & QC
Six checkpoints from material batch to finished rim, with laser layup verification and X-ray batch testing.
Wheel building
Automated lacing with tension monitoring, then a three-stage truing process by expert wheel builders.
The evidence shelf
15 testing steps before sale
Impact from 100 J, spoke pull-through, deformation, heat resistance and X-ray batch inspection. Every rim, every batch, documented in our lab.
