Sorry for the slight thread jack.
How do people like heated grips? When I had them the bottom of my hand was always hot when the top of my had was always freezing cold... Did I somehow manage to use them wrong?
That's pretty much the nature of heated grips. They've been supplied as standard equipment on snowmobiles for decades, with a high/low heat setting as they will get very hot when full current is flowing to the heat elements. Most heated grip designs use a resistor for the low heat setting. On my snowmobile, I'll start out with them on the high setting, then after a few minutes turn them down to low... otherwise they would just get too hot under most conditions running on the high setting. The other aspect to having warm hands in cold temps, is wearing gloves that have more insulation on the top of the glove, and less on the palm side so that you still have good feel on the grips.
