if i can piggyback on this thread a bit. I made a bar and stem change recently. shorter stem but I moved the brifters farther down the bar. now the angle of my wrists is actually perfectly straight when before i had my thumbs kinda coming up more. I made this change because I was having trouble shifting in the drops and i read somewhere that the bottom of the brake lever should be close to the bottom of the bar and mine were nowhere near there. now i'm having some soreness and numbness in the hands with this switch. when i first went to my old setup a few weeks ago it was also a bit sore but i seemed to adapt to it. I thought having a shorter stem would make me less stretched out and a bit more upright and actually be more comfortable. is this incorrect thinking?
