I see lots of bikes in this section with very minimal clearance between tires and frame/fork. I was wondering if that's frame design, or if a larger than stock tire/rim is being used. I mean, I've seen one pic where the poster said if they over-inflated, the tire would rub the fork.
I had wondered if it was a 27 tire on a 700c frame/fork. Out of curiousity, I stuck a 27 wheel on my Bianchi roadie (700c)... and it still had PLENTY of clearance, no where near as close as some of the bikes I've seen on here.

Really just curious.

What's the point of the minimal clearance? Looks? Aero (taken from track bikes)? Greater BB clearance?
