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. - There are 3 offsets: Standard: 47mm chainline, 6mm offset for cyclocross and road cranks Standard: 49mm chainline, 6mm offset for GXP and long spindle BB30 Boost: 52mm chainline, 3mm offset BB30: 49mm chainline, 0mm offset for BB30 short spindle cranks - Fat Bikes: If you are planning to use this on an X9 or XX1 fat bike crankset with a 190/197 rear hub spacing use the 0 offset ring. If your fat bike has a 170/177 rear hub spacing, use the Standard 6mm offset

SRAM X-SYNC 2 1x chainrings provide a high level of performance and durability. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the design reduces friction and the accumulation of mud, grit, and grime. - The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain - X-SYNC 2 chainring design increases chain retention, improves durability, and reduces friction and noise - Designed to be used with Eagle chain - 104mm BCD

Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains SRAM has ever made. The radical new look and feel of the X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. The longer, positive-rake tooth shape has been designed to work perfectly with Eagle chains to increase chain retention and overall pedaling efficiency, while decreasing friction, noise, and wear. The complete Eagle system—crankset, chainring, chain, shifter, derailleur and cassette—is designed, tested, and proven to deliver the ultimate mountain bike drivetrain. Put simply, Eagle is capable of revolutionizing the ride for all riders on every kind of terrain. - Designed to be used with Eagle chain - Material: Steel
