This frame was built by Milani in 79' for an amateur cyclist. Very nice built with just two cable guides hangers on top tube. The frame is very light and very professionaly made. The owner told me that they talked with Milani for KL tubes, but he didn't remember if the frame was then built with KL or SL tubes, . Size is 53x50 TT/ST c/c. The weight of the frame is 1650 grams without fork.
