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 Tooth’s 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.
Alternating wide/narrow tooth pattern prevents chain derailment.

COMPATIBILITY

These rings fit on the Shimano XTR M9000 and M9020 1x or 2x cranksets
Designed to meet the requirements for E-bike use.
Chainring Bolts: 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 chainring’s standoffs from the outside of the crankset
Drivetrains: 1×9, 1×10, 1×11 and 1×12 drivetrains. Not compatible with SRAM Flattop AXS or Shimano HG12+ chains.
If using a 9-speed drivetrain, use a 10-speed chain. It fits tighter for better chain retention.

DROP-STOP TECHNOLOGY
Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability. See below for Drop-Stop A compatibility.

RECOMMENDATIONS

We recommend the use of a clutch style rear derailleur for the best chain security.
If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
