Specialized Sirrus X 4.0

The Specialized Sirrus X is much more than just a fitness bike: it is a versatile platform designed for commuting, gravel roads, and light off-asphalt exploration. Thanks to the semi-upright position, wide tires, and intuitive single-chainring drivetrain, it offers comfort, control, and simplicity in every situation.

Advanced comfort with Future Shock
The Future Shock 1.5 system with 20 mm of travel absorbs vibrations and shocks from rough asphalt and gravel, improving stability and reducing fatigue over long distances.

Lightweight and responsive frame
The A1 SL Premium Aluminum alloy frame with Fitness geometry is designed to offer a balance between efficiency and comfort. The FACT 9r Carbon fork increases steering precision and helps absorb vibrations.

SRAM NX 1x11 drivetrain
The 40T single chainring configuration with an 11-42t cassette guarantees a wide gear range, ideal for tackling challenging climbs and long flat stretches with precise and reliable shifting.

Total versatility
The Plug + Play provision for racks and fenders makes the Sirrus X perfect for both daily urban use and more adventurous excursions.
