Every number on this page is measured, not marketed.
We design our carbon wheels and set how every one is wound, molded and tested. When a figure matters to you, it links to the process and the test data that produced it.

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
UCI impact, spoke pull-through, deformation, heat resistance and X-ray batch inspection. Every rim, every batch, documented in our lab.
Testing & validation ↗ Published technical papers
