Hi. I'm new here and looking for information on a trainer. I don't want to ruin my tires, but I don't want to swap them out, either. I have a road bike and my wife has a hybrid. It would be a pain to swap tires on both to use with a trainer. I found a Minoura E-RDA-1050R-PM. It is a rim drive. It is magnetic, but has "PowerMatic" which is supposed to provide exponential resistance.
What are people's opinions of Minoura trainers and rim drive trainers. Please let me know. This model seems to fit my bill (price, features, etc.) but I don't want to get it if it's no good.
