Specialized's Roubaix SL4 Comp UDi2 is an all-day endurance beast that's the perfect upgrade for riders looking for more performance without spending a fortune. Specialized's SL4 FACT 8r carbon frame has all the road absorbing, engineered compliance that you'd expect, while providing all the responsiveness and performance you need for epic days in the saddle. Paired to the top-shelf frame is a FACT carbon fork, optimized for stiffness while providing peerless steering responsiveness. When you feel like throwing down big watts, you'll have the incredibly stiff and smooth-running Fulcrum Racing S-19 Light wheels rolling beneath you, transferring every last drop of your power to the road. Shimano's Ultegra Di2 drivetrain delivers a ridiculously smooth and seamless shifting experience, while the Zertz elastomers add to the plush riding by adsorbing road chatter. An aluminum cockpit and cushy Specialized carbon CG-R seatpost all combine to make sure the Roubaix SL4 Comp UDi2 keeps you stronger and fresher for mile after mile.
Specialized's FACT (Functional Advanced Composite Technology) carbon frames and components are made from the finest materials and utilize a unique manufacturing process that creates amazing durability, awesome efficiency and super-low weight.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.
Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
