I was wondering if you can comment on how handlebar roll affects hand and wrist position while riding. I had a coaching session with a local guy here and he rolled my bar upwards so that I effectively had more stack height. It immediately felt more comfortable, it seemed like the way the bar sweep worked with that angle put my wrists in a more comfortable position. I did not think about it too much until I stripped down my bike and forgot to mark the handle bar to put it back. Obviously the way you roll the bar will also change the reach and stack but do you have any rules of thumb for getting forearms and wrists are in a strong comfortable position. Or am I barking up the wrong tree here?
