Smooth, comfortable and efficient: The Sirrus X delivers the smoothest ride in its class. With larger, confidence-inspiring tires, a slightly more upright riding position, and a highly intuitive 1x drivetrain, you'll experience maximum comfort and control.

Rider-first engineered: Like all Specialized performance bikes, the geometry of each frame is uniquely designed. For each frame, the size of each tube segment is carefully chosen to achieve the optimal balance between stiffness, weight, and responsiveness. This way, no matter the frame size, you experience the best possible ride.

Agile: Lightweight, exceptional pedaling efficiency, and precision steering provide confident, almost telepathic riding behavior.

Lightweight A1 Alloy frame with neat internal cable routing, 1.7 kg lighter than our Crosstrail Hydro model.

Maximum control thanks to intuitive shifting with 1x8 wide-range drivetrain and powerful hydraulic disc brakes.

Effortlessly glide over rough terrain with fast-rolling Specialized Pathfinder 42c tires with Gripton rubber compound.
