Men's Sirrus Alloy Disc

2018 Men's Sirrus Alloy Disc

If you're going to get in shape, you need to move, and nothing wants to help you move faster than our Sirrus with powerful hydraulic disc brakes. 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 SL Premium Aluminum, and it features a reliable set of components that are built to withstand years of daily abuse, 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.
