Details
The Roubaix SL4 Comp Di2 is what you might call an "upgrade," as this endurance-bred bike is head and shoulders above its competition. After all, we designed it to be more than just a step-up from an entry-level road bike. Instead, it's a race-ready machine that's tailored to long, hard rides in less than ideal conditions. And to make sure of it, its FACT 10r carbon fiber frame has been outfitted with Shimano's 11-speed Ultegra Di2, an ultra-stiff Praxis crankset, and smooth-rolling Axis Elite wheels. Of course, you'll also benefit from our proprietary technology that's been tested and proven on the cobbles of Northern France, like our vibration absorbing Zertz inserts throughout the frame and fork and a compact race design. So go ahead and push it to the limits—the Roubaix can take it.
