Specialized S-WORKS TARMAC SL4 Di2 (2013)

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 lightShimano Dura Ace Di2 components and Roval Rapide CLX 40 wheels: no wonder it's the go-to bike for pros on Saxo Bank-Tinkoff Bank and Astana.
