Description
With the Roubaix Expert Ultegra Di2 Disc, Specialized have created a road bike that can match the performance of dedicated race machines, but offers so much more in the way of comfort and compliance.
The frameset is constructed with Specialized's FACT 10r carbon fibre, a ridiculously lightweight and stiff material that makes this bike accelerate at the slightest push and climb with ease. By placing the Future Shock suspension system above the headset, the stiffness of the frameset is not compromised by the 20mm of travel. The extra compliance can certainly be noticed by the rider, who will enjoy riding on rough road surfaces all the more.
The FACT carbon CG-R or "cobble gobbler" seatpost features integrated elastomer inserts that dampen road buzz through the saddle for an even more stable ride.
With top-quality electronic shifting provided by the Shimano Ultegra Di2 groupset, gear changes are crisp and accurate, firing at the touch of a button. The hydraulic disc brakes offer unrivalled modulated stopping power through the Roval C38 wheelset. With carbon rims that are tubeless ready, this is a premium set of wheels to match the specification of the bike.
