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.
We started with a high quality FACT 9r carbon fibre 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.
