  • 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.
  • 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
      • If you have a BB30 crankset (30mm diameter Aluminum Spindle) this measurement will determine whether it is a long or short spindle:
        • Compatible with all 10, 11, and 12 speed chains (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).

            Complimenting Products:

            • For a longer lasting and more durable direct mount chainring with a bashring option, check out the Stainless Steel SDMs our the CAMO System that offers Stainless chainrings.
            • We recommend using a T25 L-Wrench like this one or similar for removal and installation of the bolts.
            • The stock bolts are easily damaged when removing them to install a direct mount chainring. We have replacement bolts if you need them.

              • 52mm for Boost with 3mm offset (148mm rear hub spacing)
            • A T25 Torx wrench is required to remove the bolts that secure the 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
