I use my CaadX mostly for commuting and the occasional zone 2 or recovery ride. It has a cross crank (46/36) but I have a nice Force compact (50/34) laying around and thought it might make a better overall option on the CaadX. Outside of having to move the front derailleur and replacing the chain, what are the potential issues with this? I ride a compact on the other bikes but usually ride those faster too. Does the 46/36 crank work better for commuting?
