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.
