1k filament winding machine. Patented, pioneered by Venn in 2015.

01

Patented carbon filament winding

Our patented filament winding process ensures precise and accurate carbon fiber layup: each fiber is oriented exactly as intended by our engineers. This computer-controlled technique guarantees maximal strength and durability with uniform stiffness throughout the rim's circumference, so your wheels remain true for their entire lifetime.

We use slit tape filament winding: carbon fiber tape pre-impregnated with resin. This delivers an exact, optimal resin content consistently across every wheel, eliminating variability.

Precise fiber orientation for optimal strength.
Uniform stiffness for lasting wheel trueness.
Exact resin content control via slit tape.
Maximal durability and performance consistency.

1k tape, 1,000 fibers, laid under computer control.

PLC controlled molding

Venn carbon rim molding press

Cure held at ±1 °C and ±0.1 bar, start to finish.

A PLC controlled molding process using high tolerance molds with a specially treated surface, with layup preparation in a clean room environment to eliminate surface and layup imperfections. Temperature and pressure are held precisely through the entire curing cycle, ensuring:

Uniform resin distribution for material consistency.
Elimination of voids and inconsistencies for structural integrity.
Perfect fiber-to-resin ratio for optimal weight and strength.
Consistent wall thickness for predictable performance.
03

Six quality checkpoints

Every wheel passes multiple quality-control checks through the manufacturing process, from raw material batch to the finished, laced wheel.

Check 01

Material inspection

Pre-preg carbon fiber validation and batch testing.

Check 02

Layup verification

Laser projection systems ensure accurate fiber placement.

Check 03

Cure monitoring

Real-time tracking of temperature and pressure cycles.

Check 04

Dimensional inspection

Post-cure checks against precise geometric tolerances.

Check 05

Surface finish QC

Inspection for cosmetic perfection and structural integrity.

Check 06

Final assembly check

Verification of spoke tension, trueness, and balance.
