This could be caused by several things. First make sure that what ever gloves that you use are fully cleaned and dried out before you go on your ride.

I have found that the problem is generally a combination of not wearing enough on the feet and body and a lack of circulation in the hands caused from pressure from the handle bars. If your sure you are wearing enough on the rest of your body you may wish to try to tackle the hand circulation issue first.

There are several important nerves in your hands and depending on your personal anatomy your could be putting excessive pressure on one of them depending on your favorite hand position on the handle bars. If you are using mountain bike style handle bars I would recommend that you use the nice anatomical type of grips. they are more comfortable and have more surface area to support the hand so it puts less pressure on the hand. I also use long bar ends with a thick wrap of tape to put my hands in other positions to reduce hand pressure in the same spot.

Generally, cyclist want their bikes to be as light as possible so they use little bar wrap on the handlebars. This is good in hot and warm weather. But during the cold the hand needs more insulation and pressure relief from the bars. I wrap my drop type handlebars with polyurethane garage door weather striping for a super thick and padded handlebar. It works very well as it's tough and has a firm sponginess that soaks up a lot of shock and spreads out the pressure. It also insulates your hand from the cold metal handlebar.

I also have found cycling and ski gloves ineffective for really cold weather riding. Ski gloves don't work well in a constantly sweaty environment and cycling gloves are generally not heavy enough for really cold conditions. What I have done that works the best for me is to use a standard cheap single layer medium thick or thick fleece glove. You want it to be cheap and completely breathable. then you need to get a good quality ski glove or mountaineering glove shell to put over it for wind protection. You can take them apart really easy to wash the liner and the combination is really warm.

Cheap ski gloves from Walmart with the linings removed work well for the shell and will do nicely in a pinch. Make sure that all waterproof linings have been removed.
