I have a Bianchi Pista that I purchased used from a local guy, unfortunately, it is too small. It's a 57cm and I need a 61cm. It didn't bother me too much at first, but it's gotten a little annoying the more I ride it. The question is should I replace it with a properly sized Pista, or should I upgrade to something with a bit more quality. With selling my old frame and a brand new Leader 721 frame and fork I have lying around I could afford to upgrade to something nicer, like a Pista Concept or a Bareknuckle if I could find it.
