One of the reasons I wanted to hold on to a mini pump was due to the fact that I always seem to own several bikes at a time and enjoy riding different bikes for different reasons. Having each bike equipped with a saddle bag, spare tube and or patch kit is enough but I still don't equip each bike with its own pump. I wanted a frame pump for my bikes and considered getting a couple different lengths, perhaps a shorter one to throw in a bike pannier or hydration pack until I found the Park Tool PMP 5 Dial Adjust Frame Pump. If you've ever compared the efficiency of a frame pump to a mini pump you know that instructor was correct in his statement, particularly when properly inflating to higher pressures. That's one of the reasons Crank Brothers mini alloy pump has a "high volume" or "high pressure" switch at the base of the handle. What that amounted to was having to pump, pump, pump and pump some more and yet even some more until some folks are so exhausted after a flat repair they don't feel like riding. I'm kidding of course but you get the idea. With a frame pump like that from Park Tool that is not the case where even at high pressures the pump performs smoothly and rather effortlessly.
I used this pump at a job where I needed a convenient method of maintaining tire pressure on the sales floor of a major bike retailer. Rather than using a cordless drill tire inflator which was very loud and obnoxious to customers this pump proved to be fast, quiet and efficient enough for me to keep up with my work. I used this pump on countless tires without issue of higher pressures requiring me to stress or strain. Of course the pump head of the Park PMP-5 can be used with either presta or schraeder valves by unscrewing the cap and inverting the round rubber washer and tip.
With an overall length of 19" when collapsed and approximately 17 1/2" when compressed the PMP-5 fits nicely inside my hydration pack. It also fits safe and snug on the rear rack of my 20" wheeled folding Dahon when tucked under the rack bag.
I don't know if I have said enough here about how tried and true this excellent pump has served me over the years. Knowing how it performed at work under daily use conditions which it was not designed for only proved to provide more confidence in the Park Tool PMP-5 Frame Pump to work when I need it to, which thank goodness is very rare as I rarely get flats.
