I use my portable pump(s) a lot. For my own flats(Schwalbe/Continental slicks) and other riders';
fellow riders stopping me on the bike paths w/ out a pump and for riders on charity events I volunteer
for. Five Boro Bike Tour, at least 6 or 7 every time. Same thing with New York City Century. NY Bike MS,
Tour de Cure, Escape NY, Tour de Bronx, JC Ward Tour, etc., etc.
One of my earlier Topeak Road Morph G; the valves started to leak a bit - got rid of it. Tried the Planetbike
Versair; similar to the Morph -no gauge. It was nice and operated the same way; but I've broken the foot
piece twice. Planetbike has lifetime warranties on a lot of their products. And they sent me a new one every
time.
Tried the Lezyne Micro Floor Drive HPG; similar layout to the Morph and Versair. But I found the handle
to be too small and uncomfortable for my small hands.
Tried the Crankbrothers Gem L. Pumping was supposed to be fast & easy with hi volume to start; then
switching to hi pressure. It had the same weakness as most short/tiny pumps. Needs lot of pumps and
strength to get to a useful pressure.
Currently I'm back to the tried and true - Topeak Road Morph G.
