Does the chainline configuration on a 10spd double differ from a 9spd double? If so by how much?
If I were to change the current 22/32 rings on my Deus XC to say a 26/38 (with 10spd rings) set up and fit the relevant 10spd double front mech, would it just be a simple case of bolting the rings on as they came off?
Or would I have to change the position of the rings – say put them on the other side of the tabs to get the correct chain line?
Just thinking of ways to go 2×10 with decent front rings and make them fit my nearly new cranks as the new XT double ones are £180 and a couple of rings would be £50’ish
