It features many of the same technologies that are used in Specialized's top-tier road bikes, but it shapes them into the realm of fitness.
To do so, they 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 the best part of the new Sirrus, though, the new Future Shock. Essentially, it's a piston in the head tube with 20mm of travel. This technology was developed 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, Specialized found that smoothness, speed, and comfort could be improved 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 a 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. It'll leave you feeling like you have the perfect partner on your path to health and wellbeing.
