I'm not taking it as a personal attack. As I mentioned, I'm curious to see whether this concept gains acceptance by competitive riders. Some of the comments are amusing though. If it's not for you for whatever reason, that's all well and good. But just because one rider sees no value in its application, that doesn't invalidate the concept. I deplore the idea of using CO2 to inflate my tires. Doesn't mean it's a bad idea. Just bad for the environment.
