Specialized Sirrus X – comfort, efficiency and easy handling
The Specialized Sirrus X is designed for riders who want outstanding comfort, performance, and precise handling regardless of terrain. This bike adapts seamlessly to city streets, gravel paths, or forest trails, making it a reliable choice for both daily commutes and weekend adventures.
Key Features:
- Smooth and comfortable ride: larger tires, a slightly more upright riding position, and an intuitive 1x drivetrain deliver more confidence and comfort.
- Rider-First Engineered™: each frame size is individually engineered to ensure the perfect balance of stiffness, weight, and responsiveness, so every rider enjoys the same top-level ride quality.
- Lightweight and precise: a carbon fork combined with an A1 SL aluminum frame provides lightness and efficiency, while the Future Shock 1.5 with 20 mm of travel enhances comfort and control on rough surfaces.
- Adventure ready: wide-range Shimano Deore 1x12 drivetrain, Racktime rear rack, integrated DRYTECH fenders, and additional Shimano dynamo-powered lights ensure functionality and safety both day and night.
