I've been commuting to school or work for about 25 years, and I've reached a point with numbness in my hands where it's really uncomfortable and I'm biking less with my kids than I'd like to.
Any kind of pressure on the heel of my hand (over the nerve) makes my hands go numb in about five minutes. I have to constantly shift positions on the handlebars while I'm riding. I ride a road bike in a fairly upright position to lessen the pressure on my hands.
Does anyone make bike gloves with some kind of hard shell over the part of the palm where the nerve is? I've tried just about every kind of padding, both gell and regular, and it's just not working for me.
