Sram x sync 2 eagle direct mount chainring offset 6mm 12 speed grey

the radical new look and feel of our 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 we subjected every size of chainring to untold environmental and mechanical tortures abuse and neglect in both lab and real world settings to come up with a chainring that would augment the eagle drivetrain s performance in all conditions the longer positive rake tooth shape has been designed to work perfectly with the new eagle chain to increase chain retention and overall pedaling efficiency while decreasing friction noise and wear features x sync 2 chainring design increases chain retention wear life and reduces friction and noise designed to be used with eagle chain material forged and machined aluminum compatibility eagle 12 speed dimensions boost or 49mm chain line sram direct mount weight 66g 28 dents 68g 30 dents 71g 32 dents 76g 34 dents 91g 36 dents technologies x sync 2 eagle is the n
