Wolf Tooth Direct Mount Chainrings for SRAM 8-bolt Cranks replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet. They feature our patented Drop-Stop® design for the best wear life, chain retention, and mud clearance. Drop-Stop B is optimized for SRAM Eagle and Flattop chains.

Compatibility

  • Aero chainrings available in 46-52T. Sizes 34-44T are non-aero.
  • These direct mount chainrings will replace your existing chainring and spider or replace the direct mount chainring for SRAM AXS cranksets and other cranks that use the 8-bolt mounting standard.
  • SRAM Direct Mount DUB road cranksets use the 8-bolt mounting standard. Any of those cranksets with a removable spider also use the 8-bolt mount.

  • Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability
  • For 38-52T chainringsChainline is 45mm on standard spindle cranks and 47.5mm on wide spindle cranks. For 34t and 36t chainrings Chainline is 47mm on standard spindle cranks and 49mm on wide spindle cranks for wider tire clearance in bikepacking applications.
