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.
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 is plenty durable, while the rack, fender, and disc mounts give you an incredibly versatile package.
- The Specialized XCT lock-on grips provide plenty of grip, and with their Body Geometry design, they're design to reduce numbness and increase comfort.
- A Specialized Canopy Sport saddle offers plenty of support and cushion to ensure you're comfortable out on the road.
