Well his graphic helps me understand why my hand is so messed up. I broke the base of my 5th metacarpal, and dislocated the top two knuckles in my ringer finger and the bottom 2 in my pinky finger. It’s been a year and i still get all kinds of swelling and tingling feelings. I actually just switched my bike seat to put me in a more aggressive posture, somehow being bent more forward puts my wrists at a better bend and I’m holding more weight with my back. It’s helped my comfort level when riding.
