I just got home with a Nishiki Olympic 12 frame- $20 for the entire bike minus the rear wheel. The lugwork on the headtube and the headbadge made me want it. But the wheel that came with the bike is a 27". If I choose to fix this bike, can I expect any pedal strike issues from the BB being 4mm closer to the ground? I know it sounds like a small distance, but it's an honest concern, so I'm asking. Thanks.
