I have 2 Raleigh bikes down with BBs (plus a Bridgestone down with a broken BB).
1 is an 78 Raleigh Super Grand Prix- I have that one apart and confirmed it is 26TPI.
Sheldon's site indicates that Raleigh 26 tpi was used well into the 90s, but would rather order replacement parts before tearing it apart and risking losing things. If it is 24 tpi I'll either put a cartridge BB in there.
Anyone able to confirm the Raleigh USA built 87 Technium is old Raleigh Nottingham 26 tpi rather than 24 tpi?
Alternatively, are there 26 tpi cartridge BBs out there?
