Whether you’re out for one hour or six, the Specialized Ruby SL4 Comp Ultegra Di2 is built to perform with incredible speed and comfort on the rides you love. This amazing machine sports Specialized's FACT carbon frame and fork with a feathery-low weight, for a bike that rides fast, smooth, and with unrivaled comfort. Perfect shifting is at the tip of your fingers thanks to an Ultegra 11-speed Shimano Di2 drivetrain that brings crisp, smooth shifts every time. Lightweight Axis wheels spin easily up the hills and track confidently on descents, while Specialized Turbo Pro tires and a fatigue-busting CG-R carbon seatpost make sure whatever you road you choose, you'll have a smooth, enjoyable day on the bike.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.
Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
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.
Specialized's FACT (Functional Advanced Composite Technology) carbon frames and components are made from the finest materials and utilize a unique manufacturing process that creates amazing durability, awesome efficiency and super-low weight.
