Specialized Tarmac SL2
The new frame, apparently dubbed the S-Works Tarmac SL2, appears ideally suited for a powerful sprinter like Boonen with an altogether stouter construction. As compared to the Tarmac SL, the SL2's top tube, down tube, and chain stays are substantially larger in diameter, and the seat stays abandon the S-bend in favour of a straight shot from the seat cluster down to the dropouts.
