2014 Tarmac SL4 Comp Ultegra Di2

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.
