This is a 96mm BCD chainring for a 1X chainring for XTR M9000 crankset with the proven chain retention of our Drop-Stop chainring. They fit only the Shimano XTR M9000 and M9020 cranksets (race and trail respectively). They have an asymmetrical 96 mm BCD with built-in threaded standoffs to provide the ideal 1X chainline.
Fits 96 BCD XTR M9000 and M9020 cranksets
Drop-Stop technology. On Wolf Tooths patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.
Compatibility: These rings fit on the Shimano XTR M9000 and M9020 1x or 2x cranksets
Use only the stock Shimano XTR chainring bolts (M7x.75)
You will not use the stock bolt caps when mounting this ring. The stock bolts will thread into the chainrings standoffs from the outside of the crankset
For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
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)
Chainline 49 mm for 30-34T and 50 mm for 36T. Provides a great chainline on most boost bikes
Available in two different tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains.
