Specialized Sirrus X1 (2025)

The Sirrus X offers the smoothest ride in its class. With larger tires, a slightly more upright riding position, and an intuitive single-ring drivetrain.

DESIGNED FOR THE RIDER

Like all Specialized bikes, the geometry of each frame is custom-designed. This means that for every frame, the size of each tube is specifically chosen to achieve the optimal balance of rigidity, weight, and responsiveness, ensuring that no matter your frame size, you will experience the world's best ride.

AGILE
