How much should a new mag trainer vibrate? My lady friend just got a Cycleops Mag+ and it vibrates a great deal more than I expected it to. I threw another bicycle on it and the same thing happened, so I don't think it's the wheel being out of true. Looking at the roller part, it looks like it wobbles back and forth as it spins, which could explain the vibration. I can't imagine riding on it for even half an hour because the vibration is all through the frame, the pedals, and the bars.
What do you think? Should she bring it back and see if another one works better?
