cheers - I'll update after riding tomorrow ...
I have that setup for the last 12,000kms and all good. I intend to keep it that way as I've never noticed any change in vibes and put a new chain on at the same time.[/QUOTE]
I ran the 525 chain with a 44t 520 rear... never noticed any vibration & found it was a good set up and the 44t rear was perfect for the riding I was doing.
However, being a tight-ar*e I went to the full 520 set up; but have now found it wears twice as quick, so will be going back to the 525 system when my current chain is knackered.
