ROSSIN aerodynamic time trial or fast stages model from early 80s Rare and fascinating Rossin frame, we didn't find this model in the catalogs, but it had some of the features of the Rossin Laser frame set, built with Columbus Air tubing. This frame doesn't have Columbus Air tubing but has a compact geometry, aerodynamic central downtube shifters, and a sort of triangle shaped fork blades and rear chain stays: they probably have been bent in Rossin workshop with a specific dig Unfortunately the painting is not well preserved as the tubes, but it's quite common with this kind of transparent painting on chromed tubes.
