The legendary performance of the 2015 Specialized Tarmac has taken the next revolution in bicycle design that starts and finishes with the rider. Featuring Rider-First Engineered™ technology, every size frame has been developed independently based on the real-world stresses from rider input. The result is a complete performance advancement for every frame size. It’s the newest addition to the Tarmac family and along with the SL4, it’s sure to provide all the performance you’ll ever need.
The 2015 Tarmac represents a revolution in bicycle design that begins and ends with the rider. Called Rider-First Engineered™, the technology was inspired by Specialized’s partnership with the leaders in Formula 1 development, McLaren. Each of the seven frame sizes are developed independently, based exclusively on the real world stresses introduced by the corresponding rider. The result is a significant advance of complete performance in every frame size, from 49 to 56 to 61, and everything in between. In short – breakthrough climbing, sprinting, cornering and performance for riders of every size. Because, as Specialized say…. There’s only one bike you care about. Yours.
On disc-equipped Tarmac frames, Specialized tucked the caliper neatly inside the rear triangle. Engineers slightly beefed up the stays to handle additional braking forces, but the changes add only 80 grams to the disc frames.
Instead of a traditional seat collar, the Tarmac uses an internal binder that shaves 35mm from the seat tube. That allows the 27.2mm seat post to flex slightly, increasing comfort.
