I am so glad I found this product.I used to make due with a far, far inferior emergency pump. It did "work," but just barely - I could inflate my patched up tubes enough to get back on the road, but it took forever and I could never get them to the recommended PSI.After enough frustrating experiences with the old pump, I decided to see what the new state of the art was. I was excited to see Lezyne's offerings, since I'd recently been very impressed with their pedal wrench.In use, the pump is highly effective. You don't need a ridiculous amount of strength to operate it. You *will* get a workout from all the reps you get pumping with this guy, but it's part of the tradeoff you have to make of max pressure versus max volume, and it's not that bad. I can reach the proper PSI on my road bike tires, something that wasn't even possible with my last pump.The pump I purchased is the "small" version, because based on the measurements it seemed like it would fit my emergency saddle bag. It does. A hair under 7.5" long and with a diameter of just under 1", it's like a slightly supersized cigar. A mounting bracket is included (which can sit beside your water bottle holder) but you may not even need it. The device is small enough to fit in a jersey pocket.How nice it is to handle something that's made out of metal. The pump feels like a quality product and it is.Probably the most clever bit of design is the reversible presta/shraeder tube, which stows away inside the body of the pump when not in use. You screw it onto the pump when you want to use it, giving you a lot more breathing room than you get with most pumps that are rigid and just stick right onto the valve. With the flexible tube I can move the pump around to the optimal position for pumping while it's attached to the wheel.I don't know how much it weighs, but the general answer is "not a whole lot." It's certainly lighter than my last pump.Bottom line? It's a really great product, a really clever design, and a reasonable price. Get it.

I've tried other hand pumps but this one is definitely one the of the best ones I've had experience with. Best part about it is that it has a presta/shrader valve that fits neatly inside the pump - making it a very convenient item to bring along your rides.

Se anuncia como el mejor producto y hay un modelo que en sus imágenes aparece. Sin embargo el que llegó es más pequeño y de baja capacidad

Spent some time reading bike site reviews before selecting this pump for my new bike. I needed a small light weight pump which could also get up to the 110-120psi required by my tyres. This pump seemed to tick all the boxes in that respect.The pump seems well made and sturdy in the hand, it also looks really nice. It fits nicely into the hand and is comfortable to use, not that I have had to do that it in anger up to 100+psi yet! I like the flexible ABS hose which means you can grip and hold the pump body firmly and pump efficiently without worrying about stressing the valve stem. The hose is also reversible so can either fit a Presta valve or Schrader.Excellent value and quality pump.

Good pump works well
