Men's Sirrus
2019 Men's Sirrus
If you're going to get in shape you need to move, and nothing wants to help you move faster than our Sirrus Disc. It takes a no-nonsense approach to its design, giving you everything that you need, like superior braking, 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, powerful hydraulic disc brakes that provide reliable stopping power in any condition, and comforting Body Geometry touch points that are sure to take the sting out of long rides. Complacency just met its match.
