Specialized Sirrus X 

Specialized Sirrus X is the hybrid bike designed for those who want to go beyond tarmac without sacrificing speed and comfort. From the home‑to‑work commute to gravel roads and light trails, this bike gives you total control on every terrain.

Fast-rolling, comfortable, efficient : the wider, high‑grip tires provide confidence on rough asphalt, dirt and gravel. The slightly raised riding position reduces back and shoulder fatigue, while the 1x drivetrain is intuitive, quiet, and always ready with the right gear.

Rider-First Engineered : like all Specialized performance bikes, every Sirrus X frame size is specifically designed to offer the best balance of stiffness, lightness and responsiveness. Whether you’re short or tall, you’ll always get the same precise and engaging ride feel.

Agile and responsive : the low weight, excellent pedaling efficiency and precise steering result in almost “telepathic” handling. In the city, on bike paths or on hard-packed dirt, the Sirrus X is the ideal companion for anyone looking for a versatile, fast and fun bike.
