The conti trainer tire is great. Problem is that you can't ride it on the road. It seems like it will last forever, and i've been told i can expect over 5,000 miles on it, that's more than i'll put on the trainer in a while, so it's worth the 50 bucks. I used to get black crud all over the floor and trainer when using other tires, none of that which is nice, i also would only get a few months out of a tire on the trainer, and after just a few rides i wouldn't feel comfortable taking it out on the road anyway because of that flat spot that was worn in the tire. Get the right tool for the job and you will be happy.
