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
- 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
-
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
Recommendations
- 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.

 Tooth shape is nearly identical to Drop-Stop A, but has narrower teeth. Valley between teeth is deeper to accommodate larger rollers on Flattop chain. Outside faces of narrow and wide teeth touch chain to guide alignment. Drop-Stop B Chainrings |
 The original Drop-Stop tooth profile. The wide teeth are wider than Drop-Stop B. Outside faces of narrow and wide teeth guide chain alignment. Drop-Stop A Chainrings |
 Narrower teeth than Drop-Stop A. Wide teeth use Symmetric Trapezoidal (ST) profile to match extended inner edge on chain to create alignment (outside faces of wide teeth do not touch). Interaction of narrow teeth and chain are similar to Drop-Stop A and B. Drop-Stop ST Chainrings |
*We are in the process of migrating most Drop-Stop A to Drop-Stop B to make them compatible with SRAM Road and Transmission (T-type) Flattop chains.
