Wolf Tooth’s SDMchainrings 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 SDMchainring.
• 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 Tooths 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 chainring or spider to the crankarm.
• AnL-wrenchworks 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
