This is the highest angle one I could find, and it's what is currently on my bike. It says +85 degrees, but it's more like +70 degrees. Still an improvement over my +60 degree one that this replaced, and the added stack gets me really close to a touring position. I'd like just a little more hence looking into these other ones.
