Specialized Roubaix SL4 Expert Disc UDi2 2016 - Road Bike
Smoother is faster, especially on long distance rides and the Specialized Roubaix SL4 Expert Disc UDi2 is a smooth as they come. The high modulus carbon fibre frame with endurance geometry and built in vibration damping combined with electronic shifting ensures that you will ride at your best for longer.
Carbon frame and fork
The stiff and lightweight FACT 10r carbon fibre frame is built with high modulus fibres and offers a responsive and efficient ride. While vertical compliance is built in for comfort lateral and torsional stiffness remains very high for efficient power transfer and direct steering response. This is the same frame that is found on the Roubaix Pro Disc Race.
The FACT carbon fork features size specific steerer tube tapering which offers the optimum balance between lightweight and stiffness for each frame size.
Vibration damping
As well as the natural vibration damping properties of carbon fibre the Roubaix features ZERTZ inserts in fork blades and seatstays. These viscoelastic dampers absorb road vibrations that travel through the frame when riding over rough road surfaces. Reducing road vibrations that hit the body reduces fatigue so that you can ride further for longer.
Electronic gear shifting
The Shimano Ultegra Di2, 11 speed groupset with compact chainset offers unrivaled shifting precision. With gear changes being controlled electronically you can be sure that shifts are quick, clean and precise each and every time you ride. Additional shift buttons can be placed wherever you want them on the bars to suit your riding style.
Hydraulic disc brakes
Shimano BR-785 hydraulic disc brakes offer powerful and refined stopping power that is unaffected by weather conditions. Featuring good modulation it is easy to apply just the right amount of power so that you can control your speed with confidence.
Fulcrum Racing S-19 Disc Light wheels are strong, lightweight and reliable.. just what you need for bashing out the miles all year round.
The Specialized Roubaix SL4 is an endurance road bike that is perfect for sportives, long distance epics and as well as short hacks over rough road surfaces.
Features- High-modulus SL4 FACT 10r carbon frame with tapered head tube and compact race design provides incredible responsiveness, while the engineered compliance and Zertz inserts smooth out vibrations and road chatter.
- The Specialized FACT carbon fork comes in three different sizes with varying steerer diameters that optimize stiffness for that size, while also providing excellent steering response. Road chatter is also absorbed through the Zertz elastomer inserts.
- The incredibly smooth-running Fulcrum Racing S-19 Disc Light wheels will help transfer your power to the road. They're with butted alloy spokes to be tough enough to handle even the roughest roads and still come back for more.
