The Björn Mager signature frame has been redesigned from the ground up so to start completely fresh it got a new name, the Action frame. It has an overall quick responding geometry, a well rounded slim look and some fresh new colors and features a quick 75.5° head tube angle, a 11.6” BB height, a 13.5” center of dropout chain stay length and a 8.5” stand over. Top and Down Tube have been slimmed down and the chain stays have been widened to fit 2.3” tires easily.
