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, providing the perfect blend of everyday efficiency with the performance you need to hit your fitness goals at speed.
- The FACT 9r carbon fiber 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 fiber fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders.
- The Praxis Alba M30 crankset is lightweight, durable, and aids in smooth, crisp shifts.
