The size is 59 cm and is stamped on the bottom bracket shell. Medici sized their bikes center to top of top tube. 57.5 cm is the c-c measurement. Stand-over height is 33". The 023 stamped on the bottom bracket shell designates this as the 23rd Pro Pista frame Medici made. I won't try to tell you what year it was brazed. I'm certain you can find that out somewhere on the internet if it's important to you. The lug lining and pinstripe work was probably done later. Campagnolo Pista 170mm crank arms with Campy 1/8" x 46 tooth track chain ring. Drive side has been highly polished but left arm has not been polished. Tubular Gimondi rims and sew-up tires do hold air. Campagnolo large flange Record track hubs, Cinelli Criterium 40 cm wide handlebar and Cinelli pista stem (120 mm) as well as a Campagnolo Super Record seat post with yellow Selle San Marcos Concor saddle complete this vintage track bike. I am not including pedals.
