They make "hand deflectors" for motorcycles that are basically little windshields for your hands, have you considered trying something similar on your bike? Or are you not moving fast enough for the wind to be an issue, it's just how cold it is?
The wind definitely affects things, but its also partly glove choice and mostly less good circulation than in years past. Gripping the bars and also keeping fingers on the cold aluminum brake levers speeds the heat drain too. Mittens would be better but I have to find a non-bulky pair. I will look at these deflectors too, thanks!
