The Specialized Sirrus X 4.0 Hybrid Bike is engineered for riders seeking the perfect balance of comfort, efficiency, and nimble handling on pavement, gravel, dirt trails, and mixed terrain. Designed for fitness, commuting, and adventure, this versatile hybrid bike offers the ultimate combination of lightweight performance and smooth ride quality.
Smooth, Comfortable, and Efficient Hybrid Riding
The Sirrus X 4.0 delivers an exceptionally smooth ride thanks to its Future Shock 1.5 suspension system, offering 20mm of front compliance for comfort over rough roads and uneven trails. Confidence-inspiring wide tyres and a slightly more upright geometry enhance stability and rider control, while the lightweight A1 SL alloy frame paired with a carbon fork reduces weight by 1.6 lbs (.8kg) compared to the previous 3.0 model, making it one of the lightest, most agile hybrid bikes in its class.
Rider-First Engineered Geometry
Every Specialized Sirrus X frame is designed with Rider-First Engineering, ensuring each frame size has optimized tube profiles for ideal stiffness, weight, and responsiveness. No matter your size, you get precise handling, efficient power transfer, and a ride tailored for comfort and performance across long commutes or weekend adventures.
Agile, Precise Handling
The Sirrus X 4.0 is built for nimble urban commuting and trail versatility, combining class-leading lightweight construction, exceptional pedaling efficiency, and precise steering. The wide-range 1x11 Shimano CUES drivetrain ensures smooth, reliable shifting for effortless gear changes, while the Future Shock 1.5 and responsive fork absorb bumps to keep you in control on rough surfaces.
