I was looking to get a bike trainer before the summer heat (in Arizona) comes along. But I have a few concerns about getting the indoor trainer. One, how long do they last (fluid trainers)? Second, how much will it wear on my rear tires? Should I get a cheap rear tire to use for the trainer? I feel like that would be a hassle though..unless I get a knew wheel to go along with it. And finally which brand is more reliable, Kurt Kinetic, Travel Trac (Performance Brand), or Cycleops.
