The Bianchi Infinito CV uses a Italian threaded bottom bracket shell (36 mm x 24 TPI), a 35 mm threaded bore, 70 mm wide.
It is a threaded shell (36 mm x 24 TPI, both cups right-hand thread), so the bottom bracket screws in rather than presses. Confirm the shell width before buying, because the same thread is cut in more than one width.
