I was using 3x9 XT setup, but am now using the XT cranks with Superpro 40t and 28t up front. Seems to cover what I had with the 3x9
Thinking about dropping the 28 to a 26, as a couple of hills I'm still struggling, but then again I'm not that fit.
Also have changed the rear to XTR 11-36 10 speed.
So far, it's good.
But on some runs I do,I think a 42 tooth would be better.
