Specialized's Ruby Double balances comfort with speed and stability. The secret is Specialized's super light and comfortable FACT 9r-carbon frame and fork that get up to speed quickly, handle nimbly, and take the sting out of rough roads for all-day fun. This bike boasts a wide-range Shimano Tiagra drivetrain with enough gears to let you spin up any hill. Smooth-rolling Specialized Axis wheels climb quickly, and inspire confidence on fast descents. An assortment of Body Geometry components help keep comfort high, whether you're on a short spin or an all-day adventure.
