Roubaix Expert Di2

Smoother faster lighter more control—we could go on and on when it comes to the all-new Roubaix Expert with Shimano Ultegra Di2. If we were to describe it in one word though it would be "revolutionary." The frame is the lightest that we've ever made and it's 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. 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 new Roubaix outperforms anything on the market. Lastly we spec'd it top of the line equipment like Ultegra Di2 shifting hydraulic disc brakes and tough DT R460 disc wheels.
