Looking for a 1X chainring for your Shimano compact triple crankset - models M782, M672, M622, or M612 – with the proven chain retention of our Drop-Stop® chainrings? Wolf Tooth has what you need in this beautifully machined chainring with threaded standoffs that proved and ideal chainline.

  • Fits any 96 BCD Shimano symmetric 4-bolt crankset

  • 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 any 96 BCD Shimano Symmetric bolt pattern crankset, and here are instructions on how to measure your BCD.  
  • Compatible with the following Shimano crankset models: M782, M672, M622, M612
    • Not compatible with XTR M9000 or XT M8000
    • 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 - 49mm.  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.

Details

Details

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 navigate_next

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 navigate_next

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.

*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.
