The Bianchi Specialissima is built as a race geometry frame, the Colnago Y1Rs as a race geometry frame. The Colnago Y1Rs cockpit is slightly shorter, by about 7 mm. Across matched sizes the Bianchi Specialissima and Colnago Y1Rs front ends are within a few millimetres of each other, so posture will depend more on cockpit setup than on the frame.
