powitte,
I never thought that,,,I use my hands alot and it does seam to be a stabilization thing,,
I did injure both my hands a few years a go pulling up deck boards. lifter one side and when the board popped loose both my thumbs were messed up for weeks..never been the same.
todays 12 miles were not as bad...took it easy and moved my hands alot to find the sweet spot.
also I am going to work on adding a little padding.
any other ideas?
