Cages really don't bother me too much - with one exception: Does anyone remember the handlebar/stem - mounted Blackburn cage? It had a flimsy mounting plate to "secure" against the underside of the stem? I had one years ago and 10 miles into a Century ride (LAW - when they still were LAW - used to run them on Long Island in Septembers) - it ejected my bottle on a rough section of road. I stopped, went back and could not find it. After that, I stuck with one frame-mounted cage and the jersey pocket on longer rides.
