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?
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Again, "Raleigh USA" was a licensing of the Raleigh name to Huffy in 1982 and then transferred to Derby International in 1987. Raleigh bikes sold in the US from that point on were US made and had standard English threading.
As you can see from the website, the BB is 24T, not the old 26T, yet I've only been able to get the detached cup into the shell. I do need to clean the threads, as it has been waaaay too long since, but even now the old BB cups will thread just fine. So, I'm either installing it the wrong way (cup on wrong side), TPI is mismatched (which doesn't seem right), thread direction is mixed (not sure about that either), or I just need to clean the darn thing.
