S-Works Roubaix Dura-Ace Di2

For years you had to choose between stiff and snappy or compliant and comfortable for a race-bike—that is until the new Roubaix. Featuring a completely Rider-First Engineered™ frame our Future Shock technology and a top-level build kit the S-Works Roubaix with Shimano Dura-Ace Di2 is right at home at a local fondo a Saturday group ride or a cobbled road race.

The frame is one of the lightest that we've ever made and it's been constructed from our top-tier FACT 11r 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.

We spec'd our cobble-crushing S-Works frame with the legendary performance of the Shimano Dura-Ace 9150 Di2 electronic build kit and 9170 hydraulic disc brakes a full assortment of S-Works bits and hand-built Roval CLX 32s with the legendary CeramicSpeed bearings and custom hubs. Add it all up and you get a race bike at heart with the technology to float over the roughest roads.
