Émonda SLR 9 Disc is an ultralight, aerodynamic carbon road bike that's designed and built to be the fastest climbing bike we've ever made. You get the legendary ride quality of our lightest platform, plus more speed, thanks to aero tubes wrought from our lightest OCLV layup ever. Shimano's highest-end wireless electronic drivetrain and our best climbing wheels give you every edge against the competition.
