Not sure on the golves side I'm afraid - but a shift in your riding position too may help ease the weight from your hands/wrists.

Try to grip more with your thighs/knees and tilt your pelvis forwards - this will help to remove the pressure on your wrists by making your stomach and back work harder.
(Another way to describe the tilt in your pelvis is to simply try sticking your bumout a bit!)

Also try not to curl your upper body over the tank. Shoulders back and head up - then bend from the waist rather than the chest.

Once your muscles get used to the extra work they will support your upper body more and leave your hands with the lightest of touches on the bars.

Hope that helps some.
