Wolf Tooth Components Drop Stop Direct Mount Boost Chainrings for SRAM

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.
