The Nitro Express is a flat out steel racing machine. It is built with Columbus' top end Niobium Spirit tubing. The primary tubes for triple butted Spirit tubing are drawn to 0.5 mm on the ends down to 0.38 mm in the center of the tubes. This gives an extremely lightweight steel frame that is both stiff and comfortable. The Niobium alloy used with Spirit increases the frames resistance to environmental elements.
The Nitro Express is the only Torelli steel frame available in 1 1/8" head tube.
