our frame materials
Steel
Steel offers an unmatched combination of strength, durability, and ride quality, with modern frames featuring thinner walls and optimized tube shapes for a responsive yet robust ride. Its high stiffness allows for smaller tube diameters, resulting in a frame that balances comfort, performance, and longevity, making steel a timeless choice for cyclists.
Titanium
Titanium offers an exceptional strength-to-weight ratio and excellent vibration absorption for a smooth yet lively ride. With natural corrosion resistance, high fatigue strength, and the ability to flex without losing durability, it delivers both resilience and long-lasting performance, making it an ideal choice for cyclists seeking top-tier quality and endurance.
