Bman,
I recall that it could be mounted anywhere along on the top tube, but right behind the stem would be the best place to realize the aerodynamic advantages of changing the stem from a cylinder to a wing. I'm confident that it did not obstruct the stem in any way, and it was thicker than the top tube by a few centimeters on each side. Also, I believe that the claim of 110 seconds over a 40K time trial was not due to the water bottle alone, but due to all of the adjustments to bike, equipment and rider, of which the new water bottle was a component. The data I saw verified that the water bottle prototype was one of the most aerodynamic water bottles tested.
