The Acciaio is built for long sojourns in the saddle and grand col mountain climbing. It has a longer wheelbase and slightly taller head tube than our frames with race geometry to reduce rider fatigue on gruelling big ride days. The Acciaio is a lightweight and responsive frameset. The presence of carbon, magnesium, molybdenum and vanadium in the steel tubing creates stiffness, allowing you to push the limits of your fitness. A taller head tube blended with race geometry puts this frame at home on any race circuit or gruelling sportive.
