Another Wally scratching head moment. ...It seems not, got an old frame, saracen rufftrax circa 92, with bolt on freewheel type rear wheel. Tried to put in a regular modern cassette type rear wheel and would you believe it, new wheel hub is longer than old and will not slot between stays. Needs another 1cm roughly.
Why is this?
Diameter? Longer? You mean wider?
Thanks for the comments - adjusted first post.
Old wheel is narrower than modern new wheel by about 1cm and frame will not take the new wheel.
Try bending the stays apart?
I'd guess they changed the sizes so we could all run more gears maybe? I dunno fo sho tho
Modern mbs are 135mm Over Lock Nut.
Modern roadies are 130mm OLN
Frames exist in everything from 100mm OLN upwards. 120mm is a common standard for track and bmx stuff. 126mm - old roadie.
Earlier bikes(late 80s/early 90s)sometimes had 130mm hubs rather than the 135mm that's now standard.You could try removing a spacer from the non drive side(if it's a nutted axle)or fitting a shorter axle/spacer combo.Both options will probably involve re-dishing the wheel to centralise it in the frame.
Pretty sure any 92 frame would have been 135mm
I'd spread the dropouts, assuming it's steel.
steel and it has this horror since 92. Dire weld with Tange tubes

My 1991 Aluminium Orange - still in the garage - (came with early 8speed with an secret extra click thumbshifter for the 8th gear) is 135mm. 7speed screw on free-hub wheels were 126mm. If the Saracen is steel it might spring out to 135mm or you could try to get an old wheel built onto a 126mm hub.
I also had an Aluminium Orange of that vintage with 135mm dropouts, didn't stop Dave Hinde selling me two sets of XT/DX hubbed wheels with 130mm spacing, so the stuff was still available and being used at that time.(they were excellent wheels too, shame they didn't fit properly.Didn't know any better at the time, and reckon it was that that caused the eventual crack in the seatstay junction).
