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 the lightest and stiffest frame ever. No wonder it's the go-to bike for pros on Saxo Bank-SunGard and Astana, plus Simon Coffin-see him out on one *some* mornings.
