SRAM Eagle Direct Mount Boost ChainringFeaturing a durable build that combines high-quality aluminium and steel, this mountain bike (MTB) chainring ensures maximum strength on your trail riding adventures. Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains SRAM’s ever made. The radical revised look and feel of the brand’s 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 the updated Eagle chain to increase chain retention and overall pedalling efficiency, while decreasing friction, noise and wear.MTB Chainring with X-SYNC 2 TechnologySRAM X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC 2 Eagle design reduces friction and the accumulation of mud, grit and grime.Features: Material: Aluminium and Steel Use: Mountain Bike (MTB) Speed: 12 speed Bolt Circle Diameter (BCD): Direct Mount (DM) Offset: 3mm, BoostTechnologies: X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise.
