Tubulars resist pinch flats thanks to latex tubes they typically use. Tyre and rim geometry are less important factors. Guess what? You can get latex tubes for clinchers too.
Even if you don't flat the tyre, bottom out one too many times and your rim is toast, especially with carbon.
Yea - they do break. These are those same rims (the 1720g ones) where ridden cobbles, then over parking curbs (5" cement things) and finished the race - without flats on 25s.
