Hi-ho!! I stay up nights pondering the following questions: Why are tubular tires more prone to punctures? Do they have to be? Are there tubulars which are less prone to pucntures?
Also, what's the effect of the same tire on different width rims? Say you you have a 700 x20 tire, it can go on a narrow rim or a wider rim. What's the effect on the road?
