Review on LEZYNE HV Bicycle Hand Pump: High Volume 90 PSI, Presta & Schrader Compatible, Compact Bike Pump for Efficient Inflation by Brennan Buckley

It does what it's supposed to do. It's made of quality materials, inflates, attaches easily to the bike, and looks good (unobtrusive). I expect this to continue for years. Note, however, that it takes (I) 150 pumps to get my 29er hose to a rideable pressure (firm, but less than the 50psi I prefer). It's definitely a forearm workout! So much for "HV” (large volume). I am considering carrying around cartridges again as my primary means of inflation and storing the pump for when I run out of cartridges (or when friends have an apartment!). Also, it rubs the bike frame and I need to put some tape there to protect the paint. Maybe it has more to do with my wide Trek frame, but it still rubs.
