That's an excellent argument for generator hubs, but the thing that always concerns me is that I'm such a slow climber. Don't some systems require a certain minimal speed to keep the light powered? I'd hate to be slogging up a long steep uphill pass and have my lights cut out on me.

I haven't really been doing my homework on this so maybe it's not much of an issue anymore. Or is it?

At any rate, I'd probably still carry along a battery-powered light as a backup just in case.
