OK, I have read Sheldon's website (among others) and it seems to specify Nottingham Raleighs with 26 tpi BBs and headsets. I also searched the forums and haven't found anything about Irish Raleigh threading. I have recently come across a Raleigh Record made in Ireland (according to headbadge). It has cottered cranks. I have yet to take the BB apart, and was wondering if the Irish Raleighs had the Raleigh "standard" 26 tpi?
In an archive here on bikeforums, someone wrote that a BB from a 1980 World Sport from Schwinn would fit a 26 tpi Raleigh, any truth to this?
