Specialized Tarmac SL4 Comp Ultegra Di2 (2014)

With its race-optimized, FACT carbon frame, efficient handling, and increased 19% stiffness-to-weight ratio over the previous Tour de France-winning version, the Tarmac SL4 has plenty of Pro-Tour proven speed up its sleeve. Simply put: nothing is lighter and stiffer. That’s why it’s the go-to choice of the pro peloton. Ride it hard, ride it fast, just wind yourself up and go.

The Tarmac SL4 is a pure and unbridled race machine. It climbs effortlessly, descends confidently, and sprints ferociously. It's the lightest, stiffest frame we make and it shows as soon as you push on the pedals. Bottom line, you'll be faster on this bike. There's a reason it's the weapon of choice for the Saxo-Tinkoff, Astana and Omega Pharma-Quick-Step Pro Tour teams.
