SPECIALIZED 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.

• 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 Specialized Canopy Comp saddle offers plenty of support and cushion to ensure you're comfortable out on the road.
• Promax F1 hydraulic disc brakes are spec'd on this Sirrus to ensure consistent, powerful braking.
