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: The patent pending Compliance Junction frame design of the Sirrus X provides the smoothest ride in its class.

Engineered vertical compliance without sacrificing lateral rigidity translates to more comfort, control, and efficiency on all roads, paved or gravel. RIDER-FIRST ENGINEERED:

Like all Specialized carbon bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size and carbon layup is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness to ensure that no matter what size youre riding, youre going to experience the worlds best ride.

NIMBLE: Class-leading light-weight, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.
