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.

• Featuring our Rider-First Engineeredâ„¢ design that ensures every frame size has the same legendary responsiveness and smooth ride quality that you'd expect from a Roubaix. The S-Works FACT 11r frameset is our highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness, while the all-new Road Control "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.
• An S-Works Roubaix Disc fork is built from our top-end FACT 11r carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.
• Shimano Dura-Ace Di2 shifting offers 11-speeds of electronic wonderment. Shifts are as precise as it gets and the trim adjust up front ensures that chain rub is a thing of the past—no matter how extreme your cross-chaining gets.
• Comes equipped with a 40lbs spring (color: yellow, weight: firm) installed, and also includes both 13lbs (color: blue, weight: soft) and 25lbs (color: black, weight: medium) springs that can be installed to match the terrain you're riding.

Please note that this bike does not come with pedals.
