Est. 2008 · filament winding pioneered 2015

Wheels you stop thinking about.

We made the first filament wound bicycle rims, and every Venn rim model has to pass our impact test before it goes on sale. Our technology page links each core technology to the process and the tests behind it.

Four steps. One specification.

Every Venn wheelset goes through four steps: layup, molding, inspection and building. The first film is from the winding era, 2023.

Step 01

Layup to net shape

The carbon is laid up accurately and preformed to net shape, then goes into articulated, multi-part tooling, as in aerospace and rare in rim making.

Film: the winding era, 2023

Step 02

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.

±1 °C cure · ±0.1 bar pressure

Step 03

Inspection & QC

Six checkpoints from material batch to finished rim, with laser layup verification and X-ray batch testing.

±0.1 mm dimensional tolerance

Step 04

Wheel building

Machine-assisted lacing, then expert wheel builders tension and true each wheel by hand from zero tension, measured with a digital tension meter.

<5% tension variance · <0.2 mm trueness

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 model passes before it is sold.
