2012 Tarmac SL4 Pro Di2

Whether it's winning the Tour de France or a city-limit sprint, the next generation of Tarmac—the SL4—was born to race, with head-snapping acceleration and razor-sharp handling. The Pro model has even higher stiffness-to-weight than last year's industry-leading SL3 frame, and features new Di2 electronic shifting for immediate, spot-on shifting, plus Roval Fusée SL wheels.
