Roubaix SL4 Comp Di2
Overview
Technical Specifications
Geometry
The Roubaix SL4 Comp Di2 is what you might call an "upgrade," as this endurance-bred bike is head and shoulders above its competition. After all, we designed it to be more than just a step-up from an entry-level road bike. Instead, it's a race-ready machine that's tailored to long, hard rides in less than ideal conditions. And to make sure of it, its FACT 10r carbon fiber frame has been outfitted with Shimano's 11-speed Ultegra Di2, an ultra-stiff Praxis crankset, and smooth-rolling Axis Elite wheels. Of course, you'll also benefit from our proprietary technology that's been tested and proven on the cobbles of Northern France, like our vibration absorbing Zertz inserts throughout the frame and fork and a compact race design. So go ahead and push it to the limits—the Roubaix can take it. 
  • The SL4 FACT 10r carbon frame has all of the road absorbing, engineered compliance that you'd expect from a bike born on the cobbles, yet its compact endurance race design provides all of the responsiveness and performance you need for long days in the saddle.
  • FACT carbon fork is optimized for stiffness and responsive steering, while road chatter and vibration are significantly reduced via our proprietary Zertz elastomer inserts. 
  • Shimano Ultegra Di2 shifters provide next-level shifting that's guaranteed to always be crisp, precise, and right on the money.
