The Sram X01 Eagle GXP 12 Speed Crankset has been designed for riders  who feel most stylish when they stand on top of the podium. This is a completely reengineered design, employing our proprietary CARBON TUNED™ lay-up technology. Built tough, to handle aggressive lines through rock gardens and big hits wherever you find them, the new X01 Eagle™ is the strongest, stiffest, lightest crankset available. Combined with the new Eagle™ direct mount chainrings, and as an integral part of the Eagle™ drivetrain, this is a crankset that gives your ride a winning style — assuming you’re into that sort of thing.
