Innovation never stops at Specialized. When the SL6 was released, work had already begun on the SL7. Our engineers were committed to ensuring our riders would never have to choose between aero and weight again. Thanks to the best R&D resources in the world and a team of obsessed engineers, the Tarmac SL7 achieves a marriage of light weight, aerodynamics, and ride quality previously thought impossible. Brass Ring? Holy Grail? We just call it the Tarmac SL7.
