Custom carbon tubing for frame builders
Two development paths
1. Custom for a specific builder
We design around your frame concept.
After design approval, we produce the mold and deliver two test tubes before the production run.
Pricing is defined case by case, depending on geometry, lay-up requirements and testing needs.
2. Our standard tubes available to everyone

Already in production and ready to order:

• Round steerer tube: 28.6 mm (1 1/8 inch) length 300 mm
• Seat tube: 29.8 mm (1 1/4 inch) max length 700 mm (to be confirmed)

On order, we produce other inner diameters within an agreed range.
