Oh boy, you just brought back some lovely memories of Silca NASA pump launches. AT one time I thought that they were the greastest thing since sliced bread. Then, when I had a flat in the middle of nowhere and had to actually depend and use this thing in order to attempt to pump 100 pounds of pressure into my rear wheel tubular, reality struck. Of course I was on the side of a busy secondary road, in the middle of nowhere, nary a pay phone in sight, before mankind became dependent on cell phone in order to live a decent life, and , of course , at the farthese point from home. It actually did work but was qucikly replaced by the reality of a true dependable Zephap silver aluminum frame pump which actually worked and pumped and did not flex like it was going to snap at any second. The aesthetic beauty of this masterful Italian pump was quickly replaced by the reality of a pump that I could depend upon when I got another flat. The launches were actually quite lovely to watch when they occured-especially when one could witness a pump other than the color silver slowly arcing over the stopped group of cyclists.
