Wolf Tooth Direct Mount Aero Chainring for SRAM 8-Bolt - Lightweight & Durable Bike Chainring for Road & Mountain Biking | Perfect for Racing & Performance Cycling

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. Compatibility - 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. - Wolf Tooth's patented Drop-Stop wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability - Chainline is 45mm on standard spindle cranks and 475mm on wide spindle cranks for 38-44t chainrings. Chainline is 47mm on standard spindle cranks and 49mm on wide spindle cranks for 34t and 36t chainrings for wider tire clearance in bikepacking applications. - Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-Type) Flattop chains, 9, 10, 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo.
