Replaced chain, crankset/rear cassette and chain. But will not change to big ring which is 44T. Looking at it now the old shimano crankset was 42T . Anyone know if I've got a mis -match here?, also I have a 12-32T rear cassette now, so will I need new deraillers for that too?
( been riding years but not this'modern' stuff)
