The Sirrus X Comp 2019 from Specialized is both an impressive fitness bike while being an adaptable bike for the commute. The bike's versatility comes from its 700x38mm tyres that let you explore the dirt when the time arises as well as a 1x11 drivetrain for ease of use as well as easy to use rack and fender mounts. The high quality FACT 9r carbon fibre construction of the frame means the bike is lightweight and extremely responsive. This light bike makes climbing hills smoother and is a much easier bike to carry up the stairs after your commute.
The best part of the Sirrus X is Specialized's Future Shock "suspension" system, a piston in the head tube with 20mm of travel, which was developed in partnership with the renowned McLaren Applied Technologies. This system makes massive improvements in vertical compliance which improves smoothness, speed, and comfort in one fell swoop.
The fast-rolling, 2Bliss Ready Tracer Pro tyres are perfect for adventure. The fast-rolling centre keeps resistance low on the road, while the shoulder knobs dig into corners in the dirt. And with this 2Bliss Ready design, you're able to run lower pressures for more grip and traction, while all but eliminating the risk of pinch flats. The 1x SRAM NX drivetrain ensures reliable shifting and promises no dropped chains as well as giving you next-level comfort. As you push yourself to reach your goals, you'll feel more connected to your bike than ever as the Sirrus X is the perfect partner on your path to health and wellbeing.
