Tarmac SL9 Comp One Bike To Rule Them All The Tarmac SL9 was born from the fastest road bike ever built. Not just because it’s so light. Not just because it’s so aerodynamic. Not because it handles better than any other bike on the road. But also because it delivers the lowest Time to Finish of any road bike ever made. 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.
