Specialized's Ruby SL4-Rim Brake makes sure that you have what you need to explore the road less traveled, while keeping room in your wallet for a mid-ride cappuccino. It features a FACT 9r carbon fiber frame that's been outfitted with Shimano's bombproof Tiagra components, an ultra-stiff Praxis crankset, and a whole host of women's-specific components that are guaranteed to help you get the most out of your ride. Of course, you'll also benefit from their proprietary technology that's been tested and proven on the cobbles of Northern France, like the vibration-absorbing Zertz inserts throughout the frame and fork and a compact race design.

Women’s-specific fit

Specialized's women's bikes make every ride a blast!

To optimize fit, pedaling efficiency, comfort and control, Specialized tailors the geometry and components on their women’s bikes to fit women's bodies. Size-specific frame tubes decrease weight and increase compliance. Short top tubes provide a better reach for shorter arms and torsos, while greater stand-over clearance allows for easy on/off. And, for a truly custom feel, Specialized includes small-diameter grips, shallow-drop handlebars, and women's saddles that make every ride fun and comfortable.

FACT IS Construction

This frame utilizes Specialized’s advanced FACT IS (Integrated Structure) construction method. By separating the frame into four main parts — the front triangle, seat tube/bottom bracket, chainstays and seatstays — Specialized is able to optimize each carbon piece for its specific purpose and create a structure that’s incredibly light, impeccably stiff and impressively strong.
