Compatibility

These direct mount chainrings will replace your existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the Wolf Tooth SDM® chainring. Note that the SRAM 12spd Red and Force AXS use a different 8 bolt mounting interface that is not compatible with these chainrings.
Also compatible with Cane Creek eeWing cranksets.

There are 3 offsets:

Standard: 47mm chainline, 6mm offset for cyclocross and road cranks
Standard: 49mm chainline, 6mm offset for GXP and long spindle BB30
Boost: 52mm chainline, 3mm offset
BB30: 49mm chainline, 0mm offset for BB30 short spindle cranks

Fat Bikes: If you are planning to use this on an X9 or XX1 fat bike crankset with a 190/197 rear hub spacing use the 0 offset ring. If your fat bike has a 170/177 rear hub spacing, use the Standard 6mm offset
Praxis Works Road/CX cranks use the 6mm offset. Praxis Works mountain cranks use the 3mm offset for their DM-A and 0mm offset for their DM-B chainrings.
If you have a BB30 crankset (30mm diameter aluminum spindle) the measurement pictured below will help you determine whether it is a long or short spindle.

You will need chainring to chainstay clearance for a chainring two teeth bigger than the elliptical chainring (max diameter is that of a chainring two teeth bigger).
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).

Recommendations

Recommend the use of a clutch style rear derailleur for the best chain security.
A T25 Torx wrench is required to remove the bolts that secure the chainring or spider to the crankarm.
An L-wrench works best since the crank spindle may contact a socket adapter and prevent it from engaging properly.
Use the same 3 bolts to attach the Wolf Tooth ring or if you need, we carry replacement bolts

We recommend using a T25 L-Wrench or similar for removal and installation of the bolts.
