Wolf Tooth's SDM® chainrings replace your existing spider and chainring with one clean looking, light weight, and stiff piece of machined billet. These come in 3 different offsets: standard GXP, Boost and BB30.

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.

    • Boost: 52mm chainline, 3mm offset

  • 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).

TECH SPECS:

  • Design and manufactured in Minneapolis, MN USA

  • Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability

    • Recommend the use of a clutch style rear derailleur for the best chain security.

  • Material 7075-T6

  • Colors - black

  • Chainline -

    • 47mm on cyclocross and road with 6mm offset ring

    • 49mm for standard non-boost (135/142mm rear hub spacing) with 6mm or 0mm offset (see compatibility above for which offset you need

    • 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.
