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 X1 is out to change that. It provides the perfect blend of everyday efficiency with the performance you need to hit your fitness goals at speed. To do so, we gave it a high quality FACT 9r carbon construction that's lightweight and extremely responsive. Then there's the hassle-free shifting that comes at the hands of a SRAM X1 drivetrain, plus all the comfort that follows our scientifically tested and engineered Body Geometry components. So as you push yourself to reach your goals, you'll feel more connected to your bike than ever, leaving you feeling that 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. 
  • Zertz inserts in the lightweight FACT carbon fibre fork absorb road vibration to make a smoother, more responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders.
  • Shimano Deore hydraulic disc brakes provide reliable stopping power in any condition—wet, snowy, sandy, or whatever else the road can throw at you.
