the Roubaix Comp with Ultegra Di2 represents the future of road bikes, and with one ride, you'll feel exactly why.
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 sophisticated engineering, however, we've 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 with our Rider-First Engineered construction.
Of course, you're probably thinking, "get on to the suspension thing up front." We call it Future Shock, and essentially, it's a piston in the head tube with 20mm of travel.
