Sorry rough roads up until now you've challenged only the bravest of riders to travel over you but with the Roubaix Expert with Shimano Ultegra Di2 that's equipped with our Future Shock technology the "road less travelled" is now the "fun way home."

The super-light frame has been constructed from our FACT 10r carbon fibre. 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 new Roubaix outperforms anything on the market.

This Roubaix Expert comes equipped Shimano's latest Ultegra 8050 Di2 shifting hydraulic 8070 disc brakes and lightweight alloy Roval SLX 24 disc wheels that are laced to DT Swiss 350 hubs.
