Wolf Tooth SRAM Direct Mount chainring, 8-hole, 40 t., black

Direct mount chainrings for SRAM cranks with 8-bolt mounting. These replace your existing spider and chainring with a clean-looking, lightweight, and stiff piece of direct mount chainring.

Compatibility: These direct mount chainrings replace your existing chainring and spider or replace the direct mount chainring for SRAM AXS cranksets and other cranks that have an 8-bolt mounting. Most SRAM cranksets traditionally have a 3-bolt attachment, but the 8-bolt attachment has always been used with Quarq power meter cranks. Now, some cranks without power meters, 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. Each of these cranksets with a removable spider has the 8-bolt standard.

Wolf Tooth's patented wide/narrow Drop-Stop® tooth profile ensures ultimate chain retention and mud-shedding capability. 6 mm offset, chainline 45 mm, Drop-Stop B for all 9-, 10-, and 11-speed chains or 12-speed chains from SRAM Eagle, SRAM Flattop, Campagnolo, KMC, Connex, or Wippermann, not compatible with Shimano 12-speed.
