Howard-
Oh god, This crossed my mind this morning that the frame its self could be bent. I bought it through this very parish but bought it in good faith that the frame was fine, arrived with no damage to box etc no reason to think its damaged...

So I switched some spacers around.
NDS had 7.5mm spacer which is now 5mm. DS had 2.5mm which is now 5mm.
So Ive moved the whole assembly out board by 2.5mm
Just rode up and down the street there and the slipping has stopped! Hurrah.
But... what issues has moving it 2.5mm outboard introduced? Should I really be worried much about it now or just be happy that its working the way I want it to but my feet are now 2.5mm out of position?
I don't really know much about q-factor and what it does or how it affects me to be honest. I'll have to google and read up on it.
I need articles explaining q-factor in simple terms for an idiot like me.Never had issues like this with BSA and shimano gearing... :(

I'm wondering this now. I've got digital calipers and just measured up the chain line. It does seem to be 43.5mm. Its hard to measure into the mid point between chain rings but it does look to be correct.
Wheels are second hand, its maybe possible the axle was re-assembled incorrectly at some point. This could put the cassette out maybe.
