There's no question that Eagle AXS represents the pinnacle of mountain bike drivetrain technology, but for some of us, the controller took some time to get used to. As an innovative company that listens to rider feedback, SRAM now offers the Rocker Controller to give riders that familiar feel of a traditional shift lever. It's a great option for riders that are new to AXS, or those simply seeking a more ergonomic option for their current AXS setup.
