Not heard 753 couldn't be cold set.
Maybe try asking on the TI Raleigh Yahoo group, some very knowledgeable people there (think some post here but no regularly).
Many thanks for that - I'll give the group a try.
I contacted Bob Jackson's & Brian Rourke's this morning; they both told me that 753R cannot be cold set. Bob Jackson's said that some 753 frames were built with 531 stays and could be cold set, but if a frame is made entirely from 753 it cannot be coldset. Both also said that it would be wrong to try to force-fit a 130mm rear wheel to fit, since the frame would be in a 'state of tension' and would be more likely to fail.
I've just spotted these hubs - could they be built hub into a suitable wheel ?

IF I were to use a 126 mm oln hub for a cassette, would any 6 or 7 speed cassette fit ? Would there be any sort of restriction in the range ?
Thank you for your undoubted patience !!!
