Offering an unprecedented combination of comfort, efficiency, and nimble handling, the Specialized Sirrus X excels on pavement, dirt, and any terrain in between.

• SMOOTH, COMFORTABLE, AND EFFICIENT: The Sirrus X provides the smoothest ride in its class. It features bigger, confidence-inspiring tires, a slightly more upright riding position, and a super intuitive one-by drivetrain.
• RIDER-FIRST ENGINEERED: Like all Specialized performance bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness. This ensures that no matter what size you ride, you will experience the world's best ride.
• NIMBLE: Class-leading light-weight, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.
