We deliver! Just say when and how.
Offering an unprecedented combination of comfort, efficiency, and nimble handling, the Sirrus X excels on pavement, dirt, and any terrain in between.
SMOOTH, COMFORTABLE, AND EFFICIENT: Sirrus X provides the smoothest ride in its class. With 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 to ensure that no matter what size you’re riding, 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.
Even lighter (1.6 lbs../.8kg) than Sirrus X 2.0, and faster thanks to an added A1 alloy fork.
Wide-range 1x9 microSHIFT drivetrain with a 11-42t cassette gives excellent range on any road.
More powerful hydraulic brakes and premium two-piece crank design for enhanced braking power and durability in tough conditions.
