I tore my bicep last weekend and I'm going in for an MRI today. I know I'm going to need surgery and wont be able to ride outside for a few months. I'm looking at getting the Blackburn Tech Mag 6 for a trainer. I don't want to spend alot of money for one because after my arm heals the trainer will only be used for a couple months a year. The winters in Kansas aren't that bad. I can get a Tech Mag 6 for around $150, what do you guys think of this trainer?
