The new Tarmac is designed to go fast, there's no if's, and's, or but's about that-but it represents so much more than just aerodynamic prowess. With a light-weight, Rider-First Engineered frame, it delivers the best-possible ride characteristics, no matter the size. So no matter what you have planned for your new Tarmac, its ready to help you achieve your goals-PRs, KOMs, or podium top-steps. One bike to rule them all. With the new Shimano 105 Di2 12-speed group to bring electronic shifting to the masses, along wtih some fast rolling tires in the Turbo Pro 700x26mm tires, this new Tarmac delivers performance at a more palatable price point.
