Men's Sirrus—Single Speed
The Men's Single Speed Sirrus is the perfect blend of comfort and ease of use. No need to worry about shifting, just hop on and start cruisin'.
It's constructed from a durable, reliable, and lightweight A1 Premium Aluminum, and it features a reliable set of components that are built to withstand years of daily abuse, like comforting Body Geometry touch points that are sure to take the sting out of long rides. You'll also find rack and fender mounts, so lugging your stuff around town just got a whole lot easier. Complacency just met its match.
- Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency. The A1 Premium Aluminum construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
- 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.
- The 700x30 Espoir Sport tires offer superior flat protection.
