The Specialized Roubaix Comp Ultegra Di2 Disc delivers a superb performance while bringing a new level of comfort to the world of premium road bikes.

The FACT 10r carbon fibre frameset is lightweight and stiff, climbing and accelerating with ease, while the Shimano Ultegra Di2 groupset delivers superb crisp electronic shifting and unmatched modulated hydraulic disc braking. Future Shock suspension is a truly innovative development from Specialized, offering 20mm of vertical compliance above the headset, while the CG-R carbon seatpost dampens vibrations through the saddle. A DT Swiss R470 wheelset completes the specification, with a lightweight construction that's rigid and durable for a reliable, fast-rolling ride.

Specialized Roubaix Comp Ultegra Di2 Disc Road Bike 2019

Enjoy comfort, speed and agility in equal measure thanks to the innovative Specialized Roubaix Comp Ultegra Di2 Disc Road Bikes.

Whatever your frame size, Specialized have Rider-First Engineered the FACT 10r carbon fibre tube shapes to optimise the handling, so that the performance of the Roubaix is consistent across the range. The material used is seriously lightweight and stiff, so you can climb with ease and mix it up with the sprinters of the bunch.

What sets the Roubaix apart from its competitors is the inclusion of some key design details that make this the most comfortable road bike in its class. The Future Shock suspension system delivers 20mm of vertical compliance to the front end of the bike but, importantly, this is located above the headset, so the power transfer through the bike is not affected. To add some extra damping to the rear end, the infamous "cobble gobbler" CG-R seatpost has a carbon fibre construction with integrated elastomer inserts.

Shimano supplies their superb Ultegra Di2 groupset with crisp and instant electronic shifting at the touch of a button. Stopping power is modulated and powerful thanks to the hydraulic disc brakes. Rolling on a set of DT Swiss R470 Disc wheels, handling is nimble and assured, with the 28mm Specialized Turbo tyres providing plenty of grip.


  • Rider-First Engineered design that ensures every frame size has the same responsiveness and smooth ride quality that you'd expect from a Roubaix
  • The FACT 10r frameset holds its own with Specialized's highest-end carbon offerings, with the ideal blend of overall low weight and targeted stiffness
  • All-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control
  • Shimano's Ultegra Di2 with hydraulic disc brakes not only offers exceptionally smooth and crisp electronic shifting, but it also provides incredible stopping power and modulation
  • DT Swiss R470 Disc wheels feature reliable, sealed cartridge hubs, and 24 front and rear spokes that keeps weight low and durability high.
