I have the same bike! Yes, they do. Though when he (Coach Troy the Evil) says "this and that gear" or "this and that chain" I have no idea what he is talking about since I'm not a road biker. But they have also a screen showing what effort you are supposed to use (different heart rates) and I know that very well. I always wear my hr monitor and I know my bodys different levels of exertions, so I have no problem with the "gears'.
He is very motivating. For me exact intervals are very important. I hate the "just a little more" stuff. I must know exactly how long is that little more (my runners backround). Coach Troy is that way, giving you an excellent workout in your home. The rides are harder and a lot more precise then Johnny G. Now I do JG on easy days.
Another very good one is Jay Blahnik: Precise Cycling video. Good intervals on the spinning bike.
Again, I do recommend Spinervals, I just love them. Money best spent (together with the spinning bike). I don't know if you can send them back if you don't like them, but they are always sold on ebay for a very good price. Mari
