I was using a 2x10 Deore M615 Group set (24/36 front chainrings). I just changed it out after stripping the crank arms to a RaceFace Ride XC Crankset with a 32T chainring and have not seen any major different when riding on the roads. I do however feel it on the trails currently and still need to get use to it or get a new 40/42T gear for the rear.
