Product Description


Specialized Sirrus Expert Carbon 2018

Probably the smoothest riding hybrid/flatbar road bike ever, courtesy of it's Sirrus carbon frame and Future Shock suspension.

(Future Shock suspension was previously reserved for Specialized's award-winning Roubaix road race/sportive bikes.)

Here's how Specialized describe their Sirrus Expert Carbon 2018

We understand that fitness bikes can get a bad wrap. All too often, they err on the side of value over performance, leaving you feeling in between, and frankly, a little burned. But we're happy to say that our Sirrus Expert Carbon is out to change that by providing the perfect blend of everyday efficiency with the performance you need to hit your fitness goals at speed.

To do so, we started with a 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. Onto what we like to think is the best part of the new Sirrus, though, our new Future Shock. Essentially, it's a piston in the head tube with 20mm of travel. We developed this technology in partnership with McLaren Applied Technologies, and the result of this relationship are a host of drastic performance improvements, namely in the vertical compliance department. Without giving a physics lecture, we found that is improves smoothness, speed, and comfort in one fell swoop.

We equipped this bike with a wide range of gears from the Shimano & microSHIFT components, plus next level comfort that follows our scientifically tested and engineered Body Geometry components. So as you push yourself to reach your goals. It'll leave you feeling like you have the perfect partner on your path to health and wellbeing.

  • 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. And the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.
  • 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.
