Specialized's Diverge Expert X1 can handle flying on the tarmac all day long, but it really comes to life when the adventure of leaving the pavement comes in. The light, responsive FACT 10r carbon frame boasts plenty of tire clearance for the lightweight Axis 4.0 wheels shod in 700x30/32c Specialized Roubaix Pro tires. They let you float over rough roads and poorly maintained gravel. As does the 1x11-speed SRAM Force 1 drivetrain with the ideal gear range and low weight, less parts, and locked-on chain management. For long-ride comfort, the Diverge also includes a Ti-railed Body Geometry Phenom saddle, gel-padded bar tape, and Specialized's CG-R carbon seatpost to make every mile feel just as good as the first.
