Easy to use and moves almost as much air volume as a floor pump but still fits easily into my hydration pack. Thread on head means you don't have to worry about breaking the valve on the tire and you can inflate a 29x2.35 in about 20 strokes. This pump is made for the new plus and fat tires but also works great on standard MTB tires.
I don't know what the guys who wrote the review was taking about when he said threading the hose on would be problematic over time It's all CNC's alloy and seems super durable. I have used other pumps where you slide the whole pump head on the valve and have seen that style break the valve stem clean off while pumping. With this Lezyne pump the hose threads on to the valve and you can pump to your hearts contact without fear of breaking the valve stem off.
Super little pump, does the job and fits into my jersey pocket or use the included clip that mounts under the water bottle cage.
Okay, my Serotta is more beautiful. But, this is a seriously well designed pump. I have the polished silver version and it really classes up my shop. And, of course it works great, too. I really like the pump-head, easy to use with either valve type, no leaking. Pumps to pressures over 200 psi... which is crazy, but kind of cool. The gauge is large, easy to read. Pump is tall so you don't have to bend way over while pumping.
