SRAM knows you have a lot of choices when choosing a crankset, and that choice says a lot about your personal style. SRAM designed the X01 Eagle crankset for riders who feel most stylish when they stand on top of the podium. This is a completely reengineered design, employing SRAM's proprietary CARBON TUNED lay-up technology. Built tough, to handle aggressive lines through rock gardens and big hits wherever you find them, the X01 Eagle is the strongest, stiffest, lightest crankset available. Combined with the 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.
