The perfect solution when you need something smaller than a 30t on your 104/64 BCD cranks or your 11-speed Shimano XT and SLX 96/64 BCD cranks. Also, they look great when paired with our 104 BCD bash ring on a 104/64 BCD crankset
-
Fits any 104/64 BCD crankset (104 BCD is the middle/big position 64 is the smallest ring position)
-
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
- Fits any 104/64 BCD crankset (104 BCD is the middle/big position 64 is the smallest ring position)
- The Universal Model fits both 104/64 BCD cranksets and the Shimano 11 speed XT M8000 cranks and SLX M7000 cranks.
- If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention
- Chainline (approximate as BB centering and cranksets vary)
- Chainline is 46 mm on a triple and 48 mm on a double crank
- Chainline on a Standard M8000 or M7000 crankset is 48mm and 50mm on a boost version.
- You will use the stock bolts to mount this chainring
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.
