gonna test ride the S1, and Specialized Tarmac Elite and Comp tomorrow.. price-wise, they are all close to the same ballpark. about $2200 for the S1, Tarmac Elite about $1800 and Tarmac Comp around $2250 -- prices on carbon bikes include 15% discount.
the specialized bikes come with 105 components and S1 comes with Ultegra.
We'll see how they feel.
