Any Crankset I Want?
I'm building up an old frame and need a crank and bottom bracket. I'm looking at a Campy Centaur crank and bb combo on ebay, but I just want to make sure it will be okay. I'm unsure about what gearing I would ultimately use, but I was thinking of keeping the 52/53 on the outside and then using a larger cog in the back (17). Is this a stupid idea? It seems like on FGG those guys all use 42, 44, etc.
Also, any potential problems with aligning my chain and my cog. This seems like something that most people agonize with, but I'm not sure if I understand what to look for so as to avoid the problem altogether since I am buying a new crank and bb.
