Cycling is a great way to stay healthy and get around at the same time. Specialized realized that not everyone wants to be locked in an aero-tuck on a carbon fiber missile to get in shape while riding a bicycle. If your goal is to build fitness and do some commuting as well, the Sirrus is the perfect bike for you. Its upright geometry puts you in a comfortable position to put down some miles without needing a lower back transplant at the end of the week. 

The Sirrus 1.0 keeps it cost-efficient and simple. Bells and whistles are for later on — the 1.0 uses basic components such as rim brakes, a steel fork, and a 14-speed drivetrain to give you exactly what you need to get out there and ride. RoadSport tires offer a wire bead and Endurant casing to provide good grip and longevity while remaining durable and providing low rolling resistance. An alloy frame saves weight, and Body Geometry contact points keep you comfortable.
