Product Details

What sounds like more fun? Being locked in a steamy room staring at someone in front of you for an hour or cruising the open road along a path to total freedom and fitness? Yeah, we'd choose the latter, too, which why we designed the Women's Sirrus with a unique Step-Through design that makes getting on and off the bike, as well as putting a foot down, a total breeze.

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 Women's 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 Aldia Sport 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.
