Hi, I have a threadless stem on my bike now with all the spacers set to give me my maximum height, but it is too short. I have my seat right where I want it for my legs, but am getting numb hands sometimes I feel from the handlebars being too low. I was wondering what my best options are for raising my handlebars? I have heard replacing fork, riser stem, and adjustable stem...don't know which is better if any? Thank you for your help.

side note: Anyone recommend any gloves to cut down on hand numbness?
