Smoother, faster, lighter, more control—all could be used to describe Specialized's Roubaix Expert Ultegra UDi2, but if you had to pick just one word, it would be "revolutionary." Thanks to Specialized's FACT carbon frameset and the Future Shock suspension system at the cockpit, you are treated to a revolutionary degree of comfort and control. The cutting-edge frame is paired with an S-Works Roubaix Disc fork, which is built from Specialized's top-end FACT 11r carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design bolsters all of the above. The DT R460 disc wheels provide stable, confident handling over any terrain. The bike is equipped with Shimano's Ultegra Di2 drivetrain, which provides 11-speeds of electronic wonderment; the shifts are as precise as it gets, dropping chains becomes a rarity, and the auto trim adjust up front ensures that chain rub is a thing of the past. The powerful Shimano hydraulic disc brakes deliver fantastic all-conditions stopping power and speed modulation. Plus, Specialized's Phenom GT saddle, CG-R carbon seatpost, and plush components invite you to add more miles to every ride.

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 delivers exceptional performance.

Shifting Performance

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.

Electronic shifting is customizable.

Customization

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 shifting is light on the maintenance.

Dependability

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.
