Never too much information! I think I'll attempt to alter the severity of my grip before altering the brake levers/handlebar, maybe even delay buying new gloves (damn all these accessories are draining my bank account!)
I'm certain I'm guilty of the 'death grip.' Certain because sometimes when I'm doing nothing at all I find myself clenching my fingers - a tension spot for me, I suppose.
I'm amazed at my body's memory of good technique and the seemingly natural adaptation of my posture to maximize speed and power - it's like I never left cycling and maybe even improved in the interim. However, I definitely have to work on putting so much pressure on my hands, the left hand particularly.
When it finally stops raining (if it ever does), I'll get out there and seriously try to ease up, trying some of these techniques offered here.
Thanks all!
