Sirrus X 4.0

Offering an unprecedented combination of comfort, efficiency, and nimble handling, the Sirrus X excels on pavement, dirt, and any terrain in between. The 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. 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. Class-leading light-weight, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics. The Future Shock 1.5 delivers 20mm of compliance to give maximum comfort and control over rough terrain. The added carbon fork and A1 SL alloy frame delivers a build 1.6lb (.8kg) lighter than the 3.0 model, with no heavy hybrid featuring a mountain style suspension fork coming close.
