Built for big bikes that take a beating at the park and enduro courses we ride with the X01 Eagle DUB Crankset for our super-boost machines. Built with a 55mm chain line, this crank is destined to be installed on newer enduro and trail Boost bikes so we can run bigger chainrings than spec. The X01 crank features a lightweight shell with a foam-filled core to better stand up to impacts with a minor weight penalty.
