A decade of engineering you can check our work on.
Since inventing the filament winding process for bicycle rims in 2015, our technology stack represents more than a decade of carbon fiber innovation, aerodynamic research and rigorous engineering. Each core technology below links to the process and the tests behind it.
Wind tunnel validation run. Our CFD results are verified against physical testing, not instead of it.
Core technologies
4 disciplines · one standardMolded to a flawless wall
The same rim, every time. Articulated, multi-part tooling and layup preformed to net shape, as in aerospace and rare in rim making; every cure under controlled pressure and temperature.
Advanced materials & research
Proprietary carbon composites and high-Tg resins, with glass transition up to 240 °C characterized by DMTA, and ongoing research published as technical papers.
Aerodynamics & CFD
CFD used by bicycle brands and OEM rim factories worldwide, verified in the wind tunnel, including the world's first AI-designed rim profile, the VAR 77.
Testing & validation
A 15-step protocol including impact from 100 J, spoke pull-through, deformation, heat resistance and X-ray batch inspection, passed by every rim model before it is sold.
Carbon spokes, measured against steel
Our carbon spokes fit standard 2.2 mm rim holes, preserving rim integrity. Tensile strength exceeds steel, so we lace with a lower spoke count, improving comfort and aerodynamics, while near-zero elongation gives near-instant power transfer.
Our development process
Theoretical engineering, checked against practical cycling demands.
World-class aerodynamic optimization of rim profiles before a mold is cut.
Structural integrity and durability modeled across the full laminate.
Real-world performance validation with professional athletes and demanding riders.
Comprehensive testing exceeding industry standards for long-term reliability.
