    Roubaix Expert

    2019 Roubaix Expert

    Sorry, rough roads. Up until now, you've challenged only the bravest of riders to travel over you, but with the Future-Shock-Equipped Roubaix Expert with Shimano Ultegra Di2, 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, 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 due to 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. We developed this technology 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, we found that focusing on vertical compliance, instead of fork splay, meant that we could improve smoothness, speed, and comfort in one fell swoop. And of all the bikes that we've tested with our Rolling Efficiency Model, the Roubaix outperforms anything on the market.

    This Roubaix Expert comes equipped Shimano's latest Ultegra 8050 Di2 shifting, hydraulic 8070 disc brakes, and hand-built Roval C38 carbon fiber wheels.
