One last question then we'll let this slide. I've been using my nice road bikes on the rollers but recently wondered if using "Babe, the Blue Oxen" bicycle (38# Free Spirit) would be a good idea or bad idea. Would the heavier bike provide better balance training or less? Better effect when I use the C&V bikes on the road? No difference? Aerobic training is probably about the same: time on one = time on the others.

As I'm likely to just stay in one higher gear on the rollers the quality of the components matters not, nor the handling. A great lump will roll the same. But is it wiser to train with the lightweight bikes for some good reason? Different wheel mass, different CG, different inertia.

Would the Dept store BSO/POS geometry vs the Raleigh's sport touring geometry matter? Would it 'fake me out"? Thanks.
