The Specialized Sirrus X 2.0 provides the perfect combination of comfort, efficiency, and agility, excelling both on asphalt and off-road. With wide-section tires, a semi-upright riding position, and intuitive transmission, the Sirrus X is extremely comfortable. Like all high-end Specialized bikes, the geometry of each frame size has been individually designed to achieve the right balance of stiffness, weight, and responsiveness. No matter the cyclist's height, the riding experience will be the same. The lightness, efficiency, and steering precision of the Sirrus X offer almost telepathic maneuverability.
