Stop The Drop

Wolf Tooth direct mount chainrings for SRAM cranks with 8-bolt mounting replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet.

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. Most SRAM cranksets have traditionally used a 3-bolt mounting, but the 8-bolt mounting has always been used on the Quarq power meter cranks. Now some non-power meter cranks like SRAM AXS use the 8-bolt mounting.

All SRAM Direct Mount DUB road cranksets use the 8-bolt mounting standard. These cranksets use either 107 BCD or 94 BCD; any of those cranksets with a removable spider use the 8-bolt mount.
