We'll spare you the "Cervelo was founded in...yadda yadda" story and cut right to the point.
The reason we love Cervelo is their focus. Every product Cervelo develops filters through the brand's singular mission statement, "Does it make the rider faster?". Then, they move on if a project can't answer that question in the affirmative. Simple as that.
We understand if the products they make aren't for you - maybe you value comfort most of all, or you want a gravel bike that can put mountain bikes to shame in their own terrain. That's okay, there are plenty of bikes out there (we've got plenty of other options, too.) that can meet your needs, but if you want to go FAST, you've come to the right place.
