The deal we made with nino schurter and his involvement testing eagle axs™ in the 2017.18 racing season was this: he didn’t have to use it in actual races. But nino immediately recognized its benefits and insisted on putting it all on the line, winning four world cup races, his sixth uci world cup XC overall title and being crowned world champion. We couldn’t take it away from nino if we tried. At a glance, eagle axs™ brings the real benefits of wireless electronic shifting to the mountain bike. On a deeper level, it offers discerning riders unprecedented personalization and control of the drivetrain. On the bike and off. Deepening the relationship between machine and rider. This addition to the eagle™ ecosystem enhances capability. Removes complexity. And provides riders an experience like never before imagined. Things to remember Eagle™ is a complete drivetrain system that was developed to be an integrated high-performance ecosystem. The engineering and testing that went into the development provide for maximum performance, safety, and long-term durability to ensure a great consumer ride experience. We guarantee this performance when eagle™ drivetrains are used as a complete ecosystem.
