Specialized S-Works Roubaix Dura-Ace Di2 Disc Road Bike 2019
Through innovative design and top specification, the Specialized S-Works Roubaix Disc is a road bike that manages to combine an incredibly stiff and lightweight performance with seriously comfortable ride quality.
The frameset is constructed with Specialized's top grade of carbon fibre, namely FACT 11r. This super lightweight material is supremely stiff too, making this a bike that can climb and sprint with anything else in the peloton. What makes this bike really stand out, however, is how it deals with the imperfections of the road's surface.
Future shock is a piston in the head tube with 20mm of travel, which translates to a smoother ride experience through the handlebar. The innovative location of this device above the headset means the input performance of the bike is not affected, so the power of the rider is still maximised through the ultra-stiff frameset, but road chatter and imperfections are damped through the hands.
Boasting a full Shimano Dura-Ace Di2 groupset, you're getting the very best electronic shifting experience straight from the pro peloton. The hydraulic disc brakes deliver unrivalled stopping power which can be modulated with ease; brake as much or as little as you need to.
The Roval CLX 32 wheelset hits that midpoint between lightness and stiffness, and is built to withstand the demands of the cobbled pavé roads made famous by the Paris Roubaix spring classic road race. With ceramic speed bearings, this is a wheelset that rolls super smoothly, and with 28mm Specialized Turbo Cotton tyres is designed for fast comfort too.
Specialized have also specced it with their much-lauded "cobble gobbler" S-Works CG-R seatpost, which actively damps road vibrations for an even smoother ride.
- Rider-First Engineered™ design ensures every frame size has the same responsiveness and smooth ride quality
- The S-Works FACT 11r frameset is Specialized's highest quality carbon frame, offering 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
- Shimano's Dura-Ace Di2 groupset offers exceptionally crisp electronic shifting, smooth hydraulic braking modulation, and it keeps the overall weight of this Roubaix at an absolute minimum
- The Roval CLX 32 wheelset is the perfect balance of light weight, durability, and aerodynamics. It's stiff enough for sprinting, strong enough for abuse, and its CeramicSpeed bearings keep things silky-smooth, making them the ultimate all-rounders
