These rings fit on the Shimano XT M8000, SLX M7000 or Deore M6000 1x or 2x cranksets, and here are instructions on http://www.wolftoothcomponents.com/pages/how-to-measure-bolt-circle-diameter-bcd how to measure your BCD.
Not compatible with Deore triple (3x) cranksets!
For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains.
If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention).
Provide a great chainline on most Boost bikes. http://www.wolftoothcomponents.com/pages/boost-chainline-and-chainrings See this explanation for details.
