Description
The Specialized Roubaix Expert Ultegra Di2 Disc Road Bike is a performance oriented race machine, with a lightweight and stiff FACT 10r carbon fibre frameset. Lighter than the Venge and more aerodynamic than the Tarmac, the Roubaix also offers class-leading compliance and space for 33mm tyres, opening up a world of new route possibilities.
Between the rider and the seriously stiff frameset, Specialized has engineered two key pieces of technology to ensure a compliant ride. Future Shock 2.0 is 20mm of cobble damping hydraulic suspension, with an adjustable dial so you can firm it up for climbing or sprinting. At the back end, an S-Works Pave seatpost has a drop-clamp mechanism, ensuring more of the seatpost can deflect for uniform compliance across the bike for a super smooth ride on any surface.
The Shimano Ultegra Di2 electronic groupset offers instant gear changes at the touch of a button, with a range of gearing to suit climbs of any gradient. Hydraulic disc brakes bring superb modulated stopping power to the package, and the Roval C 38 carbon wheelset rolls superbly, performing even in a crosswind.
