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 traveled" is now the "fun way home."

The super-light frame has 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, 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 Engineered™ design that ensures every frame size has the same legendary responsiveness and smooth ride quality that you'd expect from a Roubaix. The FACT 10r frameset holds its own with our high-end carbon offerings, with the ideal blend of light overall weight and targeted stiffness, while the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.
  • A Roubaix Disc fork is built from our FACT carbon fiber for supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.
  • Shimano Ultegra Di2 shifting offers 11-speeds of electronic wonderment. Shifts are as precise as it gets, dropping chains becomes a rarity, and the trim adjust up front ensures that chain rub is a thing of the past—no matter how extreme your cross-chaining gets.
