The Frame
Award-winning steel adventure touring frame designed in collaboration with Cicli Barco, Italy. Progressively butted Dedacciai Zero Uno tube set with Reynolds 631 steel. Engineered for long-range touring with capacity for 650B x 58mm or 700c x 50mm tyres. Full-internal routing, stainless T47 BB shell, and DiffuserBlack Metallic mica finish with bronze hints.
Dedacciai Zero Uno
Dedacciai Zero Uno is a progressively butted, triple-drawn chromoly steel tubeset from the Italian specialist. Thinner walls at the centre, thicker at the joints — it delivers a remarkably light steel frame with a forgiving ride quality that rewards long days in the saddle.
