The new X01 Eagle™ is our best, toughest and most aggressive Trail and Enduro crankset thanks to DUB™ technology. The reengineered design, employing our proprietary CARBON TUNED™ lay-up technology, is built tough to handle aggressive lines through rock gardens and big hits wherever you find them. We helped by adding a new 165mm length crank arm for those lower, longer and slacker bikes.
