This along with the special bottom bracket shell, the original rear dropouts and the "bell shape" steat stays make the rear triangle properly stiff. The frame is built according to an exclusive geometry designed by Irio Tommasini. It is completely chromed, or as a second choice, all "cataforesi" treated, good for extremely thin tubings because it deeply protect them from rust. Maximum attention to detail: an example are the STI bosses (with adjusting screws included) brazed onto the head tube and the engraved enamelled head tube metal badge. Personalized carbon fiber forks available. The 55 cm frame (painted) weight approx. 1.550 kg (3.417 lbs).
