Raleigh's own thread sizes? Can any body tell me roughly what year they stopped making bikes with...

...their own peculiar threads and started using a more conventional guage. Not terribly important, just curiosity really.

I think they continued to use their own 24TPI tread on headsets and bottom brackets right through the 90's. It's certainly still a problem with people who try to change the BB on Raleigh Shoppers so that they can avoid cotter pins and go for square taper. Not too difficult to resolve if anybody is interested, just get a dremmel and grind off about 1/2 of the thread width. The 24 and 26TPI thread is the same for about the first 5/8" and that's more than enough to hold a modern(ish) BB.

 

[biggs682]

from memory on road bikes it was the late 70's

 

[mcshroom]

My criterium is (I think) late 80s and has 24tpi threads

According to Sheldon the Raleigh threading standards continued 'Right through the 90s'

ok looks like i got it wrong then .... sorry if i misled anybody

I think it depends which factory produced the bike. I've read somewhere (and I've lost the link) that the Nottingham factory used the Raleigh threading quite late on, but their other factories (acquired when they bought out other manufacturers) used British standard threading.

My own Raleigh from the late 90's uses British threads.

The Avatar left is of a 1990's Nottingham built 'Friday afternoon job'. I believe the threading to be 26TPI as the bottombracket cups are incompatible with any of the non Raleigh frames I currently have knocking around.
Presumably anything with Nottingham on the headbadge is Raleigh threaded. Although there may be exceptions, (see http://www.cyclechat.net/threads/nottingham-thread-gauges.106646/), I have not seen any with my own eyes.

I wouldn't go on the head badge. Mine says "Nottingham, England" on the headbadge but isn't Raleigh threaded.

 

[Ed no-more-lemons]

Or should I say that anything actually made at the main Nottingham factory would have the Raleigh thread gauges?
As Sheldon suggests in the above linked article that they (Raleigh) never retooled at Nottingham.

I've got a 1990 or 91 Randonneur with standard threads (& a UN52 BB in it), and Nottingham head badge

 

[Cyclopathic]

I've got an 80s/90s Raleigh I'm doing up and it has standard threads. If as Ed N.M.L says that Nottingham never re-tooled it would seem logical that Nottingham made bikes are the ones to look out for (to avoid or obtain as is ones need).
Doesn't seem quite as bad as the British car manufacturing debacle but still indicative of the lack of foresight of manufacturing management in the UK.
Thanks for your answers folks.
