The Tarmac SL stays at the top of Specialized's road range with some enhancements for 2007. As well as the new S-Works carbon chainset, all Tarmac bikes now come with an integrated ceramic-bearing headset. At the top of the range is the SRAM Force-equipped model, with Dura-Ace, Ultegra and 105 coming just below.

All bikes are fitted as standard with 40mm of head spacers, Barmac with shallow-drop bars and more useable gearing. For example, the Roubaix comes as standard with a compact drivetrain that gives a more realistic range of gears. This is a sensible move by Specialized. It may be a departure from the world of 53x11 that people seem to think they need, but in reality there aren?t many people who can use a gear like that.
