    2019 Men's Sirrus Expert Carbon

    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.

    To do so, 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.

    We equipped this bike with a wide range of gears from the Shimano & microSHIFT components, plus next level 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.

    Absolutely love this bike!

    I use this bike to commute and go on long haul rides and it is excellent on and off the road. I put Gravel King 43mm tires on it and it's basically like having a gravel bike. I can ride on road, Singletrack, and crushed stone with no problem. Very responsive and light as well. The only downfall you may come across on this bike is at higher speeds you may top out gear wise. But I'm talking speeds in excess of 40mph. Other than that this is a great bike!

    Great bike

    I have a 2019 carbon elite. I absolutely love this bike. Complete joy to ride. Handles nicely. Accelerates quickly, stops on a dime. I replaced the cheap saddle that it came with and installed a Selle Italia with ti rails. Now it rides like a charm. Fun bike.

    The only bike that you needed

    I had my 2016* Carbon Expert Sirrus, Run as I expected. I was planning to get a road bike in replace of this bike , but I have decided to upgrade the Crankcase set into a 52 36T Shimano Ultegra and cassette into a 11 34T shimano, BOTTOM LINE, run like a race bike ,run so fast on the straight road and now I can managed well on going uphill with my 11 34T cassette. Before I forget, I also replaced the pedal with spike. I am fully satisfied with this bike and with my upgrade.

    Only bike that you needed

    I had my 2016 Fitness Expert carbon bike, Run as I expected. I was planning to get another road bike, but after I replaced the crankcase set to 52 36T Shimano Ultegra and cassette to 11 34T Shimano , there is no need to get another bike. This run like a race bike, good on uphill and downhills. And you can feel the speed on straight road
