Offering an unprecedented combination of comfort, efficiency, and agile handling, the Sirrus X excels on pavement, dirt, and everything in between.
SMOOTH, COMFORTABLE & EFFICIENT: Sirrus X delivers the smoothest ride in its class. With larger, confidence-inspiring tires, a slightly more upright riding position, and a super intuitive 1x drivetrain. RIDER-FIRST ENGINEERED: Like all Specialized performance bikes, every frame geometry is uniquely designed. This means for every frame, every tube size is specifically selected to achieve the optimal balance of stiffness, weight, and responsiveness to ensure that no matter what size you ride, you’ll experience the world’s best ride.
NIMBLE: Class-leading low weight, exceptional pedaling efficiency, and pinpoint steering precision fuse for confident and almost telepathic handling characteristics.
Lightweight A1 Alloy frame with clean internal cable routing, 3.5lbs (1.7kg).
Maximum control through intuitive shifting with 1x7 wide range gearing and mechanical disc brakes.
Float over rough terrain with fast-rolling Specialized Pathfinder 42c tires featuring a proprietary Gripton rubber compound.
