Scrod,
I am rebuilding an old Raleigh Sprite into a fixed gear. I'm feeling confident about everything I'm going to do, except for the bottom bracket. I don't know exactly what year the bike is, so I can't give you specifics. But do you know, if not, know of where I can look for a bottom bracket for the Sprite?
Edit: I live in San Diego, I could always bring it into the shop.
