Last season our team's bike was the S-Works E5. A couple guys had cracks form at the head/down tube junction, and Specialized replaced the defective E5's with brand-spankin' new S-Works Tarmac SL's.

They're also the only high-end tire manufacturer I know of that has an unconditional satisfaction guarantee. Buy a Specialized tire, and if you don't like it you can return/exchange it. Pretty awesome.

Glad to hear they came through for you in a big way!
