Whether you use them is not the point. Whether you need them is not the point. The fact is they are coming. And soon -- like in two weeks, soon -- the best equipment will have disc brakes. Wait a bit longer and all the decent equipment will.

I don't want them to come either for a number of reasons. But I am rational enough to know that they are and intelligent enough to make moves to limit my financial exposure as they do. Enjoy your tubulars and your shitty old slow equipment. I'll be rolling around on my Px with HEDs for the minor upgrade consideration you were too foolish to consider when you had the chance. When you finally do decide to join the big leagues, you'll need well over $5k to do so.
