huh. i put a jazillion miles on my old road bike with a full length Silca 'frame pump' on the seat tube, one end up against the BB, other end tucked under the top tube. that pump never failed me. true, the pump 'handle' did overlap the main tube when it was compressed, so it acted as a mud guard, the shaft was only exposed when you had the pump extended. would pump up a 23c tire to 120psi in a half dozen strokes. I do NOT like those little shorty things they sell now days.
