Whether we’re chasing downhill lines or threading through techy rock gardens, the ROTOR R-Hawk Crank Arms give us the strength, fit, and freedom to ride with confidence. Built from CNC-machined 7075 aluminum, these 165mm arms deliver a perfect balance of durability and responsiveness—optimized for modern enduro and all-mountain riding. What sets the R-Hawk apart is its modular design. Sold as standalone arms, it lets us pair them with the spindle and chainring setup that fits our ride style—standard, Boost, or DH. The Direct Mount interface supports ROTOR’s oval or round chainrings with OCP adjustment, while integrated rubber bumpers (in seven colors) add protection and style. These arms are ready to be built exactly how we want.
