The Specialized Sirrus Carbon: A Perfect Blend of Urban Fitness and Gravel Riding

Now with a striking new frame design and the innovative Compliance Junction

The Specialized Sirrus Carbon bike has evolved from its origins as an urban fitness/commuting bike into a versatile option also aimed at gravel riding. The latest version features a striking new frame design with a unique Compliance Junction feature. This feature involves the seat stays joining with the suspended bottom end of the seat tube, with a strut going from that joining point to the down tube. This design is claimed to provide just the right amount of flex and forgiveness across the carbon frame without sacrificing performance and efficiency. The bike also features the Future Shock headset-integrated coil-spring shock absorber that offers 20 mm of handlebar-smoothing front travel.

The Sirrus Carbon is available in two models – the Carbon X 5.0 and the Carbon 6.0.

Sirrus X 5.0

The Sirrus X 5.0 excels on pavement, dirt, and any terrain in between, with wide 38c Pathfinder tubeless-ready tires that provide traction and comfort off the beaten path. Equipped with a minimalist yet efficient SRAM NX Eagle 1x drivetrain with wide-range gearing and Tektro hydraulic brakes with large 160mm rotors, the Sirrus X 5.0 ensures smooth and reliable shifting and reliable stopping power on- and off-road.

Like all Specialized carbon bikes, the geometry of each frame is uniquely crafted using their Rider-First Engineered™ philosophy, with each tube size and carbon layup specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness, no matter what size you're riding. The Sirrus X 5.0 is also versatile and customizable, with rack, fender, and top tube mounts, and tire clearance up to 42c for tuning your ride for whatever comes next.

The Sirrus X 5.0 is fender and rack compatible with top tube and fork mounts, and racks can be used with 51c DRYTECH fenders, making it easy to rack and roll. Its Specialized FACT 9r carbon frame features internal cable routing, and its extraordinary performance begins at its heart, the Compliance Junction, which provides just the right amount of flex and forgiveness across the carbon frame without sacrificing performance or efficiency. The Sirrus X 5.0 is the ultimate bike for riders looking to push their limits and go beyond the pavement while not sacrificing comfort and performance.

Sirrus 6.0

With a versatile and customizable design, the Sirrus 6 is equipped with rack, fender, and top tube mounts, and has tire clearance up to 42c, making it perfect for any adventure. Its minimalist yet efficient SRAM GX Eagle Lunar 1x drivetrain with wide-range gearing ensures smooth and reliable shifting, while the SRAM Level TLM hydraulic disc brakes provide optimal speed control and dependability.

The Sirrus 6 is fender and rack compatible with top tube and fork mounts, and racks can be used with 51c DRYTECH fenders, making it easy to rack and roll. The Roval Terra seatpost offers significant compliance for a smooth ride over rough terrain.

Using Specialized's Rider-First Engineered™ philosophy, the geometry of each frame is uniquely crafted, with each tube size and carbon layup specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness. The result is an alluring and superior bike in both aesthetics and performance. The Sirrus 6 is the future of riding, delivering the world's best ride no matter what size you're riding.
