Fitness is not a fad, and the Sirrus proves you're taking your fitness journey seriously. The Sirrus Sport Disc combines our premium aluminum frame with a reliable component package and powerful disc brakes to deliver a comfortable and fast ride. As you push yourself to reach your goals, the Sirrus will be a powerful ally to have on your health and wellbeing team.
The reliable and sturdy, A1 Premium Aluminum frame features rack and fender mounts, allowing you to carry gear or to fend off road spray in inclement weather.
Reflective graphics are strategically located on the bike in order to increase your visibility to other riders and motorists in low-light conditions.
Wide and stable-handling 700x32mm Specialized Nimbus Reflect tires have a fast and smooth tread, reflective sidewall, and feature Flak Jacket puncture protection.
The 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, while the Body Geometry Targa Sport saddle is designed for fitness riders and assures blood flow to sensitive arteries.
