Says 32 officially. Anyone know if 34 will work? (friction mode)

Shimano is conservative about such things. If it says 32 you can likely go 34. My Atlantis came with a Deore XT & easily cleared a 32. Never ran a 34 until after I'd worn it out & replaced with a Microshift. If it doesn't clear the 34 with the supplied "B" screw turned all the way in, you can always put in a longer one. Sheldon has something about that on his site under "rear derailers".

Come to think of it, a buddy runs an 11-34 8 speed with a low end Shimano RD. Don't recall what but it's nothing even close to Deore XT grade. Worth a shot.

I really want to get a 36 and see if it works. Thanks for the responses.

I picked up an almost new one today to start downgrading from indexed 10 to friction 8. 10 speed chains are just to dainty for me.

Ryan, I shift a 9 speed with a 36 T, the 32-36 combo works perfectly, the 20-36 needs a longer B limit screw but I still use it. Steve
