Fitness is not a fad, and the Sirrus Pro proves youre taking your fitness journey seriously. It features many of the same technologies that are used in Specializeds top-tier road bikes, but it shapes them into the realm of fitness.
To do so, Specialized started with a high quality FACT 9r carbon fibre construction thats 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 is likely the best part of the new Sirrus, though, the new Future Shock. Essentially, its a piston in the head tube with 20mm of travel. Specialized 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, Specialized found that is improves smoothness, speed, and comfort in one fell swoop.
Then theres the super wide range of gears that come at the hands of the legendary Shimano Ultegra rear derailleur, plus all the comfort that follows scientifically tested and engineered Body Geometry components. So as you push yourself to reach your goals, or simply get where youre going, youll feel more connected to your bike than ever. Itll leave you feeling like you have the perfect partner on your path to health and wellbeing.
> | The FACT 9r carbon fibre frame is engineered and designed with Fitness Geometry, helping you ride more efficiently in a position that will see you riding comfortably, mile-after-mile. And the all-new Future Shock suspension system at the cockpit delivers a revolutionary degree of comfort and control. |
> | The lightweight FACT carbon fibre fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders. |
> | Braking duties are handled by TRP Flow Set Control hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition. |
