Dynamo and rolling resistance when the light is off.
On my old bike I had a Shimano dynamo with a Lumotec CYO light. The nice thing was that when the light was off, the wheel spun free, with no added resistance that I could tell. I've still got the hub and I'm thinking about trying it out with a Supernova light. Will I still get the same effect? I don't ride at night all that much, so I'd like to not have the rolling resistance when I don't need it.
EDIT: Nevermind, I think I found my answer. Looks like most dynos have less resistance when there's no power draw. That must have been what I was noticing.
