Fitness is not a fad, and the Sirrus Pro proves you're taking your fitness journey seriously. It features many of the same technologies that are use in our top-tier road bikes, but conforms them into the realm of fitness.
We started with a high quality FACT 9r carbon fiber 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.
Then there's the super wide range of gears that come at the hands of the legendary Shimano Ultegra rear derailleur, plus all the comfort that follows our scientifically tested and engineered Body Geometry components. So as you push yourself to reach your goals or simply get where you're going, 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.
