Hitting a sweet spot between performance and value, the Roubaix Sport was designed to thrive on long rides through rough country.
The light weight frame has been constructed from our FACT 9r 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. 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.
Lastly, we spec'd the Roubaix Sport with 105 11-speed mechanical shifting, hassle-free Tektro Spyre mechanical disc brakes, and DT R470 Disc wheels that have been cased in our Turbo Pro 28mm tires.
