I actually just did this the other day to my new (to me) Dave Scott Ironman Expert. It worked well.
But actually I wanted to inflate my 27" tire and ended up taking out more of the underside of the bridge. I'll let you know if I die. On the plus side, since I'm running a 700c in front and a 27" in back, I have a sloping top tube.
