I would like to upgrade this bike with a better and faster crankset, 52-36T, but I'm confused if my planned setup will be compatible with the bike I have. I have consulted in our local bike shop and they said that a Dura-Ace crank would fit but the FD will have a hard time or impossible fitting considering the top tube design of the bike.
I'm not really sure if he saw my bottom bracket being really old. Might there be any modern bottom bracket to fit it at all?
