    3x10 to 2x10 another thread... i know

    A little advise here, ive searched but still im unclear.

    I am currently runnin xt dyna syst 3x10 and want to go with a 26x38 setup. I only use my big ring on long descents to keep the chain from jumpin around. I hate that when im in my middle ring and the top or bottem end of my cassette and my chain rubs the front derailleur, then i have to down shift the front and 2 higher in the back vise versa.

    Do i need new cranks or can i just buy shimano 26 and 38 rings to do this. I do know i will prop need a shorter cage front der.

    You just need the rings and a bash ring or shorter chainring bolts. Just set the high limit screw on the FD so it will not shift past middle position.
