Specialized S-Works Tarmac SL4 (2012)

Whether it's winning the Tour de France or a local crit, the next generation of Tarmac—the SL4—was born to race, with head-snapping acceleration and razor-sharp handling. The S-Works model features our lightest and stiffest frame ever, plus super light Dura Ace components and Roval Fusée SLX wheels: no wonder it's the go-to bike for pros on Saxo Bank-SunGard and Astana.
