I'd be interested to know what technique benefits there are to rollers, that aren't available while balancing during outdoors rides. I sometimes practice riding *on* the white line for as long as I can (more for entertainment, than training). Am I getting roller benefit from that? I've never really thought it would make me any faster.
According to what I've read online, the curved surface of the roller magnifies steering response. It makes sense that there would be some difference, since the wheel axle sits 0-1" behind the roller axle. When you turn the front wheel, the effective wheelbase shortens slightly, and the roller contacts the tire higher up. This observation only covers wheel-turning steering, not leaning. I don't know if the overall claim is true or if it's somehow related to the legalese "rollers are dangerous" disclaimers.
I was distracted once while I was riding my rollers, and rode edge-to-edge a few times before riding it out successfully, but that took a lot of luck. I don't think the rapid weaving/bobbing is even possible on the road. Having your body's momentum moving in the rough direction you want to go (forward) makes some sort of contribution.
Regarding the white line drill, I find it far easier to ride the white line than to ride a similar width strip on my rollers. My form isn't great, and road riding seems to allow more gross balance correction than rollers.
My feeling on rollers is that they provide a substitute for real riding, training balance at a low intensity. They may have additional skill benefits, but I own them so that my form won't substantially worsen during the winter.
