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 Mechanical 12-speed group, along with some fast rolling tires in the Turbo Pro 700x26mm tires, this new Tarmac delivers performance at a more palatable price point.
