Put this post in the mechanics section but they recommended I reposted it here!
I have just bought a 1957 raleigh something or other (!) and have a few queries about the whole crank set up. I have confirmed that it has cotter pins but have a few concerns;
1. The crank arm on the chain side is ever so slightly rubbing against the frame (chainstay? not sure what that bit is called but it runs from the bottom bracket to the drop out, parallel to the ground) but the bottom bracket seems to be rock solid. As it is rock solid I don't want to go messing about with the whole thing if it means a big job - which leads on to my second question;
2. With these cotterless cranks is it possible to whip the whole lot out and replace with a modern bottom bracket and chainset. Is this possible?
Sorry, know I must sound like a complete idiot - don't know much about bikes! Have included a couple of pictures in case anyone can tell me what I'm riding![IMG][/IMG]
