Sorry...it's evolved.
HT angle is 70 degrees...
To begin...I had handlebars with 76mm reach. I've wanted to swap them out with bars where due to the radii of the hook they actually end up closer to the paddles. I went with the Zipp SSR bar...that has a 70mm reach. It's easier to wraparound the levers now...
I also want to be able to stretch a bit more when in the drops, not much....so:
I've went from a 90mm, 0 degree stem with 30mm spacers to a 110mm stem with 10 degrees of rise and 12mm of spacers.
I've also incorporated a seatpost with 20mm setback versus the 16mm I have...Carbon for comfort reasons.
This tool is pretty good:
