My partner says he would choose a Cervelo every time - but his sole criteria is the fastest bike he can get... and if money were no object at all he would buy the P3.

However, he does say that you should bear in mind that the bike that fits you best is the bike you should have. And this is simply because you will get more speed from a good set of aerobars and a good set of wheels than you will from an aerodynamic frame.

He does recommend the website below... this link is to the review page.
The thing he likes about the reviews here is that this guy pulls no punches... he does not favour brands and even has an explaination about how he reviews things (see top of review links at top of page)

Tom (the reviewer) has been to here to New Zealand for IronMan and he follows the Tour de France.

He opinions are well respected in cycling circles for their honesty and integrity.

Anyways, some of the bikes you have listed are reviewed here by him... have fun making your choice
