FAST REDEFINED. Designed for speed and efficiency, yet still light, sharp-handling and smooth-riding, the Tarmac SL gives new meaning to the word fast.

When Specialized set out to build the lightest, most efficient road bike ever, there wasn't a manufacturing process that could do the job. So they created one-'Az1'. Using Az1 (say: as-one) they seamlessly join discrete carbon monocoque sections into a single chassis, creating a frame with unsurpassed strength-to-weight and stiffness-to-weight ratios.
