Materials
- Zinc plated Steel
A fine compromise that offers satisfactory mechanical properties and moderate weather resistance. - Stainless Steel
With a low environmental impact, stainless steel is known for its unparalleled weather resistance, making it the perfect solution for adventure or road bikes and for touring and racing bikes. - Carbon Steel
Carbon steel is the perfect choice for off-road activities, thanks to its high resistance to fatigue and mechanical stress. - C8 Green Steel
With a low environmental impact and high mechanical characteristics, Green Steel is the winning combination of uncompromising performance and sustainability. - Aluminum
The incredible lightness and high resistance to atmospheric agents make aluminum one of the most versatile materials. Perfect for combining performance and mechanical requirements, it is the ideal choice for motorcycles and bicycles with a sporting vocation. - Brass
Ductile and resistant to atmospheric agents, brass represents a valid compromise.
- Zinc plated Steel
Treatments
- Black ED
A low environmental impact electrodeposition surface-treatment that ensures a unique aesthetic result and good resistance to atmospheric agents. - Anodizing
An aluminum coloring process that improves its mechanical properties and resistance to atmospheric agents. - Burnishing
A stainless-steel coloring process. It ensures an excellent aesthetic result, preserving the excellent weathering resistance that distinguishes stainless steel. - Zinc-plating
A process of coloring steel-carbon that ensures excellent resistance to atmospheric agents. - Bcolor® Painting
Our indisputable trademark. Handmade in Italy, provided with a transparent protective topcoat to increase resistance to shocks and weathering. - Monocolor Painting
A refined and elegant painting. Handmade in Italy, provided with a transparent protective topcoat to increase the resistance to shocks and atmospheric agents. - Hand Polishing
