Description

The direct mount chainrings for SRAM cranksets with the 3-bolt mounting interface. They replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet. They are available in the Drop-Stop B tooth profile, which is optimized for SRAM Flattop chain. It is also compatible with all other 9-, 10-, 11-, and 12-speed chains except the Shimano 12-speed chain.

Compatibility

  • These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on SRAM cranksets including the DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle. Note that these chainrings are NOT compatible with SRAM 8-bolt direct mount cranksets.
  • Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
  • There is one offset:
    • Standard Road/CX/Gravel: 6mm offset for cyclocross and road crank applications with 47mm chainline
  • Praxis Works Road/CX cranks use the 6mm offset.  
  • 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).


Recommendations

  • Recommend the use of a clutch style rear derailleur for the best chain security.
  • 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 we carry replacement bolts

Related Products

  • For a longer lasting and more durable option check out the CAMO System that offers stainless steel chainrings.
  • We recommend using a T25 L-Wrench 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.
