actually I think my stem is 80mm long...it's a Ritchey adjustable.

let's see...I think riding the top was the worst...the hoods--with relaxed hands and my weight more on the heel of my hand--- the best, and the primary pain is at the base of my thumbs...which may also be partially due to the mac laptop...but it is noticably worse when riding. knock wood...i have no other pain issues with the bike.

i can find the photo of my pony for ya
