I have just bought a new Record 10 speed crankset (aluminium version) to replace an old Shimano 600 crankset. The rest of the drivetrain is 8-speed Campagnolo.
My plan is to make some spacers to fit between the arms and the small chainring to make room for the 8-speed chain. Does anybody know how thick these spacers need to be?
My 8-speed chain is 7,2mm wide and a 10-speed chain is 6,1-6,2mm wide. From this I would expect the spacers should be about 0,5mm thick.
I expect I can't be the first one to have done this, anybody with experience?
