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 HTC-Highroad.
Better than I could have imagined. A climbing bike that is still very comfortable, yet very responsive...like a BMW. Love the DA Di2's smooth and accurate shifting although not as responsive as its mechanical rivals. Sexy looks to boot.
