Founded in 1920 by Pietro Casati, their frames are of the highest quality of craftman ship and technical expertise. Our Frame is a stunning example of Casati skill made of high class Columbus SPX steel tubes with internal tube reinforcements. With many beautiful casati details. The bottom bracket shell and seat stay caps bear typical Casati engravings. The fork and rear triangle are chromed and the rear braking cable is routed internally through the top tube.
