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, & 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, & 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 & know that you have the perfect partner on your path to health & 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 & designed with our Fitness Geometry, so you'll be able to ride more efficiently & comfortably, no matter the distance.And the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort & control. The best part of the Sirrus? 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, & 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, & 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. Body Geometry touchpoints take the sting out of riding with their ergonomically designed, scientifically tested shapes.
