Specialized Sirrus X 1.0 Step Through

Specialized Sirrus X is the hybrid bike designed for those who want to go beyond asphalt and ride confidently on any terrain: city, compact dirt, white bike paths and mixed routes.

Comfort, smoothness and efficiency come together in a surprisingly versatile package. The wider tires offer great grip and stability, allowing you to tackle potholes, tracks and gravel with total confidence. The slightly more upright riding position reduces fatigue in your back, neck and shoulders, while the 1x drivetrain is intuitive, quiet and perfect for those who want quick, hassle-free shifting.

Thanks to Rider-First Engineered design, every frame size is optimized to offer the best balance of stiffness, weight and responsiveness. Whether you’re short or tall, the Sirrus X always maintains the same precise, controlled ride feel.

The lightweight frame, excellent pedaling efficiency and agile, “telepathic” handling make this bike ideal for fitness, commuting and light gravel . If you’re looking for a reliable, fast and comfortable bike for training, commuting or exploring new routes, the Specialized Sirrus X is the right choice.
