Wolf Tooth Components Drop Stop Direct Mount Chainrings for SRAM

Wolf Tooth's SDM® chainrings replace your existing spider and chainring with one clean looking, light weight, and stiff piece of machined billet. These come in 3 different offsets: standard GXP, Boost and BB30. Compatibility: These direct mount chainrings will replace your existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle.  You will use these same 3 bolts to attach the Wolf Tooth SDM® chainring. Boost: 52mm chainline, 3mm offset Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle) 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). TECH SPECS: Design and manufactured in Minneapolis, MN USA Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability Recommend the use of a clutch style rear derailleur for the best chain security. Material 7075-T6 Colors - black Chainline - 47mm on cyclocross and road with 6mm offset ring 49mm for standard non-boost (135/142mm rear hub spacing) with 6mm or 0mm offset (see compatibility above for which offset you need 52mm for Boost with 3mm offset (148mm rear hub spacing) A T25 Torx wrench is required to remove the bolts that secure  the chainring or spider to the crankarm. 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
