If it's really a 2013 model, then it's not square taper. It would be a carbon crank using the Ultra Torque bb system. Veloce square taper bb's are longer than Chorus so won't work. Google Chorus square taper bb and see what comes up. There could be some on ebay or new old stock. Campagnolo square taper went out in 2007 or so I believe but it shouldn't be hard to find one.
