Product Information

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 Disc.

Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort
and efficiency. The A1 Premium SL Aluminium 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 Solve hydraulic disc brakes are spec'd on this Sirrus to ensure consistent, powerful braking.
