Calm down dude, I agree with you - improving your cardio shapes has nothing to do with biking, all this talk about VO2 and stuff is just horse pukey, and lordy, all the money and time folks put into rollers so they "improve their cardio and believe they are getting to be better riders" is a total waste. Fools. I just wish my fellow club members understood what you and I do.
BTW, do you have two carbon bottle cages or just one and saving up?
