Brand-new SPITFIRE much differ from the past. Most obviously is that we successfully reduce much weight. To achieve the goal of reduction of the weight, we replace the reinforcement plate familiar to everybody with advanced technological Hydro Formed down tube. We pioneered the Hydro Formed technology on cromoly 4130. It makes frame lighter and stronger. We still use our special horizontal dropout, ASP system (Axle Stabilization Platform), so that rider can switch between single-speed and nine-speed easily.
As some riders complain about few choices of frame colors (only black, white, and grey). We now got seven colors for choice, orange, yellow, green, blue, brown, white, and black.
