Hello All,

I just picked up a frame at the Trexlertown swap meet and I'm planning on building up a single speed.

Its an '81 Raleigh Super Record, Ive done some research (from Sheldon Brown) and I'm almost positive that the bottom bracket is english thread for raleigh thread because it is the standard 68mm.

I was looking up the charts on Sheldon and I'm having trouble figuring out what bottom bracket to use to get a proper chain line for a single speed.

Im looking most for an a decent but not expensive solution, any suggestions?
