The Specialized S-Works Tarmac SL7 Dura-Ace Di2 is a no-compromise race bike that distills pure speed into a deceptively simple package. Built from Specialized’s top-tier FACT 12r carbon, the SL7 blends the aerodynamics of the Venge with the climbing prowess of the original Tarmac, resulting in a frame that feels equally sharp on a summit finish or a windswept solo break. The Shimano Dura-Ace Di2 groupset offers lightning-fast, precise shifts and a satisfyingly clean cockpit thanks to fully integrated cables. Upgraded Zipp 454 NSW carbon wheels keep it snappy and stable at high speeds, while the S-Works finishing kit — including the featherweight carbon seatpost and bars — keeps grams to an absolute minimum. For riders chasing podiums or simply wanting the sharpest edge on group rides, the SL7 Dura-Ace Di2 stands as a striking example of modern road racing refinement, where every detail is aimed at going fast, everywhere.
