Could you describe the hand pain - just general hand pain or? The only hand pain i can think of getting while riding is between my thumb and the rest of my hand sometimes. I'll just make suggestions based on what helped with my wrist pain - and some of this really may have already been addressed with your fittings, so sorry if it's way off.


Things you can look at - the angle you hold your hands on the handlebar - it should be neutral, not bending back the bar.

Move your hands while riding - don't keep them in the same place, periodically flex them.

Gel padding under your handlebar could help.

Getting a handlebar that has a wide flat spot instead of a round bar to hold on to may help - I use FSA wings.

Don't rest your weight on your hands - if you saddle tilts forwards some, this may cause you to put weight on your hands.
