Bump - I'm upgrading to XX and want to find out whether I should go with the 156 or 166 XX cranks.

I had the same issue, it looks like the XTR is more than 166Q......

you can measure your frame and see which one will fit..

there are only few frames that a 156Q will fit..... Mine was not one of them... I went for the 166Q
