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, fast, precise Shimano Di2 electronic components, and Roval Fusée SLX wheels: no wonder it's the go-to bike for pros on Quickstep, Astana, and Saxo-Bank.
