Specialized's Tarmac SL4 Comp UDi2 doesn’t just do one thing well—it does everything exceptionally. This is proven by the fact that it boasts a Grand Tour winning pedigree, and will take both your racing and riding to the next level! Its Specialized FACT carbon frame and fork boast the awesome combo of low weight and high stiffness for ripping power transfer that you'll appreciate whenever the road tilts skyward or you pick up the pace to put the hurt on your friends. Crisp, perfect shifts are at your fingertips thanks to the electronic Shimano Ultegra Di2 22-speed drivetrain, while the mid-compact Shimano Ultegra crankset makes sure you have the perfect gear for the road's ups and downs. The smooth-rolling DT wheels, wrapped in grippy S-Works Turbo tires, give you superior traction through corners and deliver road-blistering speed. Plus, you'll love the Specialized aluminum and carbon components sprinkled throughout this incredible road machine that is sure to be a great addition to your riding arsenal.

This frame utilizes Specialized’s advanced FACT IS (Integrated Structure) construction method. By separating the frame into four main parts — the front triangle, seat tube/bottom bracket, chainstays and seatstays — Specialized is able to optimize each carbon piece for its specific purpose and create a structure that’s incredibly light, impeccably stiff and impressively strong.

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 delivers exceptional performance.

Shifting Performance

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.

Electronic shifting is customizable.

Customization

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 shifting is light on the maintenance.

Dependability

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.
