Men's Sirrus Alloy

2018 Men's Sirrus Alloy

If you're going to get in shape, you need to move, and nothing wants to help you move faster than our Sirrus with hassle-free V-brakes. 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 Aluminium, 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.
