What would YOU do?

How does the top tube length compare?
Do you plan on racing?
If the top tube length is one you're comfortable with, being a cm or two taller than you're used to isn't a big deal.
If you don't plan on racing, and the top tube length is ok, I'd say go for it.
Ideally, I ride a 55 cm bike, but I have a couple 56's and even a 59. They are all a joy to ride.
