Can I put a 10 speed road cassette on my MTB which currently has a 2x10 drivetrain. I know that 10 speed MTB drivetrains use HG-X chains which are specific to MTB, but what will happen if road cassette is used? Will shifting be severely affected? Another option I guess is to use both road cassette and chain. But then - how about front shifting?
I must note that I will be occasionally switching back to MTB cassette (about 5 times a season).
