Sorry rough roads, up until now you've challenged only the bravest of riders to travel over you, but with the Roubaix Expert with Shimano Ultegra Di2 that's equipped with Future Shock technology, the "road less traveled" is now the "fun way home."

The super-light frame has been constructed from our FACT 10r carbon fiber. Its stiffness levels are also off the charts, and compared to the SL4 iteration of yesteryear, you'll experience a whole new, faster, and more efficient geometry. Through some engineering sorcery, however, Specialized managed to keep the same fit, feel, and position that we've all come to love from the SL4, and kept it consistent throughout the size-range due to their Rider-First Engineered construction.

Of course, you're probably thinking, "get on to the suspension thing up front." It's called Future Shock, and essentially, it's a piston in the head tube with 20mm of travel. Developed in partnership with McLaren Applied Technologies, and the result of this are a host of drastic performance improvements, namely in the vertical compliance department. Without giving a physics lecture, they found that focusing on vertical compliance, instead of fork splay, meant that the engineers could improve smoothness, speed, and comfort in one fell swoop. And of all the bikes that have been tested with Specialized's Rolling Efficiency Model, the new Roubaix outperforms anything on the market.

This Roubaix Expert comes equipped with Shimano's latest Ultegra 8050 Di2 shifting, hydraulic 8070 disc brakes, and lightweight, alloy Roval SLX 24 disc wheels that are laced to DT Swiss 350 hubs.

- Featuring our Rider-First Engineered design that ensures every frame size has the same legendary responsiveness and smooth ride quality that you'd expect from a Roubaix. The FACT 10r frameset holds its own with our high-end carbon offerings, with the ideal blend of light overall weight and targeted stiffness, while the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.

- A Roubaix Disc fork is built from our FACT carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.

- The Roval SLX 24 Disc wheelset features a sub-1600-gram weight, a 20-millimeter internal width, and an alloy construction that makes it a solid performer when the roads turn rough.

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.
