About the Specialized Sirrus X 4.0 Active Bike

Specialized Sirrus X 4.0: Ready for Anything, Built for More

The Specialized Sirrus X 4.0 is designed to inspire you to ride more and explore places you never thought possible. Whether you're cruising on pavement, heading down a gravel path, or navigating city streets, the Sirrus X 4.0 has everything you need to take on any adventure. With its comfortable geometry, high-performance features, and rugged design, it’s the ultimate bike for those looking for a versatile ride that’s just as capable off-road as it is on-road.

Key Benefits for Riders

Enhanced Comfort with Future Shock 1.5

Equipped with the revolutionary Future Shock 1.5, the Sirrus X 4.0 offers 20mm of compliance, providing a smooth, cushioned ride even over rough terrain. This innovative shock technology ensures maximum comfort, taking the sting out of bumps and potholes while keeping your bike handling precise and controlled.

Lightweight, Performance-Ready Build

The carbon fork and A1 SL alloy frame reduce the weight by 1.6 lbs (0.8 kg) compared to the 3.0 model, making the Sirrus X 4.0 one of the lightest hybrids in its class. The result is a responsive and efficient bike that is perfect for both city riding and off-road exploration.

Smooth, Precise Shifting

With a 1x11 SRAM NX drivetrain, the Sirrus X 4.0 provides smooth and reliable shifting, offering a wide range of gears to tackle any terrain. The one-by system ensures simplicity and ease of use, while still providing the versatility you need for long-distance rides or steep climbs.

Stability and Control with Reliable Brakes

The Tektro HD-R510 hydraulic disc brakes deliver powerful stopping power, with 160mm rotors for consistent performance in all conditions. Whether you're navigating wet streets or dirt trails, you’ll have the control and safety you need to handle any situation.

Confidence-Inspiring Tires and Grip

The Specialized Pathfinder tires, with their 42mm width, provide excellent traction and stability, ensuring a smooth ride whether you're on paved roads or gravel paths. The reflective accents on the tires also increase your visibility to motorists, keeping you safe during low-light conditions.

Why Choose the Specialized Sirrus X 4.0?

Built for adventure and designed for comfort, the Sirrus X 4.0 is a perfect choice for those who want a bike that can handle anything from commuting to weekend exploration.
