Trainers are for winter riding. If it's raining, snowing or ice on the roads I ride indoors. Cyclops adjustable mag stationary. I took it apart to add a spacers so the magnet gets closer to the rotor - more resistance. My poor old Moto stays clamped into that. Good for one leg'd spinning.

I also have Kreitler rollers and like them too. I still have to stay pretty focused on them to keep going but the focus is good for me too. I use myY2K Cannondale on those. I have a separate wheel for that bike that I use for the rollers. Easy to swap the original wheel back in when the roads are clear. I alternate between the two trainers and riding the neighborhood on Babe, the Blue Oxen, my winter Free Spirit sled.
