Ok, so i am thinking of going from X9 shifters to XO shifters, i have 2011 X9 at the moment, what i want to know is, what performance gains are to be made with the XO, i know they are lighter, but i couldn't care less about weight, is there any difference mechanically between the two?, if there is no difference between them, i wont get the XO's just for weight loss!
