2019 S-Works Roubaix

For years, your race bike selection was limited to stiff and snappy or compliant and comfortable—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 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.

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.
