Tarmac SL9 Expert One Bike To Rule Them All The Tarmac SL9 was born from the fastest road bike ever built. Not just because it is so light. Not just because it is so aerodynamic.

The Tarmac SL9 converts more of your power into pure speed – tested on real race tracks, in real terrain, by real riders. If the goal is to cross the finish line first, no other road bike will get you there faster.
