    Shimano XT 11-46T cassette along with XTR M9000 cranks

    Shimano XT 11-46T cassette along with XTR M9000 cranks-img_8413.jpgShimano XT 11-46T cassette along with XTR M9000 cranks-img_8419.jpg

    Just thought I'd let people know here that if they choose to buy XTR M9000 cranks and use them as a 1x11 set up and not a 2x11 set up they will run into a chain line issue. At least that was the case for me.

    When in the lowest gear the chain line is at an extreme angle that it rubs up on my front 36T chain rings teeth making a slight clink sound. Solution? to add shims/spacers where the crank and the chain ring bolts are. This helps but doesn't make it perfect.

    This in turn can wear your chain out a little sooner. Just wanna let people out there know.

    Anyone else have any other solutions that worked for them? Please post them here.

    Also, I realized that a Q factor of 158 was extremely narrow but it still suprised me how close my cranks are to the chainstay. REALLY close.

    Is that any different with an 11-40? Can't see why it would be.

    Weird. The XT 1x and 2x cranksets are identical, with the 1x ring just building in additional offset towards the non-drive side. Are the 1x and 2x XTR cranksets actually different from one another, aside from the rings of course?

    FWIW, Oneup's XTR 1x chainring is described as yielding the same chainline for both the 9000 and 9020 cranksets, suggesting that the two cranksets are the same.

    Yep, all of the 11x cassettes are compatible with XT and XTR. For some weird reason the XTR 1x crank I bought made the chain line very slant to the point it was grinding when in the lowest gear (46t)

    The bike shop figured out the solution and made custom shims for me, problem solved.

    This may be the case for XTR...but I don't have both cranks for comparison and I can't find anything online.

    Just thought I'd let other people who are considering buying the XTR crank to know my experience.
