My Cervelo came with mid-compact, and I frankly hated it. I would never have been one to guess that a 2-tooth difference could make such a difference, but here we are. I swapped in a set of Praxis compact rings and never looked back. My wife runs "even more compact," with 46/34 rings. AFAIC, a 52 or 53 big ring is for people who are racing, people who like to think that they're racing, and people who never want to use the 11T cog again unless falling down the side of a mountain.
