I'm new to road cycling. I keep getting numbness, or shooting nerve pain, in my right hand after 10-12 miles. I'm trying to keep moving my hands in different positions, but that doesn't seem to be helping. I've adjusted my saddle(fore, aft, tilt, etc) and that doesn't seem to be it. Has anyone else experienced this and know what it might be caused by: stem length, bar height? T doesn't happen on my mtn bike at all...so, it's something with this new position and the pressure on my hand in the hoods.
