I've got an early 80's ride with a Galaxy 2 head-badge(I've been told it's a Dawes) that I am in the process of converting, and I need some crank/bb help. It has totally worthless pot metal cottered cranks on it and I'm looking for the proper type of replacement bb and crank set, but I'm a total noob with little cash flow. Any suggestions or info wold be massively appreciated.
