Product Details

Specialized Sirrus Expert Carbon - Fitness / Commuter Hybrid

The Specialized Expert Carbon is probably the smoothest riding hybrid/flat bar road bike ever, courtesy of it's Sirrus carbon frame and Future Shock suspension.

Key Features

  • The FACT 9r carbon fibre frame is engineered and designed with our Fitness Geometry, helping you ride more efficiently in a position that will see you riding comfortably, mile-after-mile.
  • Alll-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control (Future Shock suspension was previously reserved for Specialized's award-winning Roubaix road race/sportive bikes)
  • The lightweight FACT carbon fibre fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders
  • Braking duties are handled by TRP Flow Set Control hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.
  •  Wide range of gears from the Shimano & microSHIFT components

The Sirrus Expert Carbon provides the perfect blend of everyday efficiency with the performance you need to hit your fitness goals at speed. High quality FACT 9r carbon fibre construction that's lightweight and extremely responsive, not only making the Sirrus a better climber, but also making it easier to carry up the stairs after your commute.
