Hi guys im currently running 2x9 Shimano XT, and Im thinking about going to 2x10 setup.
My question is can I remain with my current XT crankset and chainrings? or do I also have to go to 2x10 crankset and chainrings? I was just going to change the RD, RD shifter, and chain. Keep the 9 speed cranks and chainrings and FD. Your feedback would be much appreciated.
