Have to replace bearings and cups on a Raleigh BB

[IT_Dummy]

Does any member know the thread on the BB for the Raleigh Max Orge 21.
Is it 24 or 26 tpi ?

Many Thanks

No idea but you might be able to deduce from the width of the bb shell, the old 26mm seems to be 71 or 76mm while ISOs are 68 or 73mm. If 26mm this might help.

As far as I know, this will be standard English thread: the others are Italian or French, both of which are a different diameter but Italian have English thread, French have metric!!!!!

It'll have a normal thread, rather than the older Raleigh specific one. My 1993 Ascender takes a standard Shimano UN-55, and the Max is newer than that.
