2017 Sirrus

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. This means that you can expect reliable components that are built to withstand years of daily abuse, a lightweight A1 Premium Aluminum frame that's corrosion-resistant, and comforting Body Geometry components that'll take the sting out of long rides. Complacency just met its match.
