We understand that fitness bikes can get a bad rap. Most of the time, they err on the side of value over performance, which leaves YOU feeling in between, and frankly, a little burned. But we're happy to say that our Sirrus 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. This Sirrus features a super light carbon fiber construction, as well as a reliable set of microSHIFT & Shimano components that are built to withstand years of daily abuse, powerful hydraulic disc brakes that provide reliable stopping power in any condition, and comfortable Body Geometry touchpoints that are sure to take the sting out of longer rides. So, as you push yourself to reach your goals, you'll feel more connected to your bike and know that you have the perfect partner on your path to health and wellbeing. *While this frame platform was designed from the ground up for all riders, some of the models feature gender-specific touchpoints.
- The FACT 9r carbon fiber frame is engineered and designed with our Fitness Geometry, so you'll be able to ride more efficiently and comfortably, no matter the distance.
- The best part of the Sirrus? The Future Shock. It’s a piston in the head tube with 20mm of travel, so you get better vertical compliance and improved smoothness, speed, and comfort in one fell swoop
- 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.
- Women's Body Geometry touchpoints take the sting out of riding with their ergonomically designed, scientifically tested shapes.
