If you're going to get in shape you need to move, and nothing wants to help you move faster than our Sirrus. It takes a no-nonsense approach to its design, giving you everything that you need and nothing that you don't. This means that you can expect reliable components that are built to withstand years of daily abuse, a lightweight A1 Premium Aluminum frame that's corrosion-resistant, and comforting Body Geometry components that'll take the sting out of long rides. Complacency just met its match.
- 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.
- A steel, straight blade fork provides a responsive ride, while the fender and rack mounts give you the option to install rain-fighting fenders and racks that can transport your gear around town.
- V-brakes are dependable and easy to maintain, so you won't have to worry about brake bleeds or labor-intensive maintenance to have awesome stopping power.
