My 57 with a 90mm stem (ST is 54c-c, 58c-t and a slack seat tube angle) is the best fitting bike I've ever had. No way would I go shorter than 54.
Thanks all - yes, I used the calculator. I had a hard time figuring out the fit based on the tiny diagram on bianchi's website. I ride a trek 7.3 fx right now on a 22.5" and it's killing my left hand under the knuckle on the ring finger after riding and during the ride, my hands go numb. I think it's because that bike is too long for me and there's too much pressure on my hands. I rode that bianchi and there's way less pressure on my hands, but I don't know how to judge proper size by riding around a parking lot and I don't have experience with a road bike.
For reference, the particulars of measurement on that bianchi are here:
Infinito 105 | Bianchi USA The diagram has B1 and BS and I'm not sure which one to use. The TT measurement on the competitive fit calc says I should ride a 55.5 - 55.9
