Sram X-SYNC 2 Eagle Direct Mount Boost 12 Speed Gray Chainring

The radical new look and design of the X-SYNC 2 Eagle chainring is a direct result of studies conducted by SRAM's transmission engineers into the performance and wear characteristics of thousands of X-SYNC chainrings. We subjected all chainring sizes to countless environmental and mechanical tortures, mistreatment and neglect, in the lab and in real life, before arriving at a chainring that could increase the performance of the Eagle drivetrain under all conditions. The specific shape of the teeth has been designed to perfectly match the new Eagle chain, in order to increase chain retention and overall pedaling efficiency, while reducing friction, noise and wear. The X-SYNC 2 chainring design increases chain retention and life, while reducing friction and noise. Details:Wide and narrow CNC machined X-SYNC chainrings New X-SYNC tooth profile for maximum chain control Material: AL-7075-T651 Direct Mount Offset Boost 3mm Recommended channel: Eagle Sold with screws 12-speed Eagle transmission compatible Manufacturer weight: (66g) 28 teeth (68g) 30 teeth (71g) 32 teeth (76g) 34 teeth (91g) 36 teeth Technologies: X-SYNC 2 EAGLE is the next evolution of SRAM X-SYNC technology. Aggressive tooth design provides better chain retention for smoother and more efficient pedaling. With a focus on even longer life, the X-SYNC EAGLE ? design reduces friction and the build-up of mud, grit and grime.
