Description

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.

- Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency. The A1 SL Premium Aluminum construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
- A steel, straight blade fork provides a responsive ride, while the fender and rack mounts give you the option to install rain-fighting fenders and racks that can transport your gear around town.
- Promax F1 hydraulic disc brakes are spec'd on this Sirrus to ensure consistent, powerful braking.
