Rated 4 out of 5 by from Good for quick fixes This is a good pump for emergency use. It does take some effort on 700c tires near the end but what mini-pump doesn't? My fave method of use is to use this pump to start filling a tire to check that none of the tube is under the tire's bead (having any under it will result in a nasty and loud popping of your new tube). Once the tube is on its way, I then use a 16g CO2 to quickly fill it up so I can get going ASAP. As for the lame dust plug--either cut it off or leave it on and cover the entire end of the pump with a 1-inch section of old mtb tube like a giant rubberband. That really keeps stuff out.

Rated 5 out of 5 by from Great inexpensive compact pump This pump was super easy to attach under my water bottle cage. I've used it on numerous occasions and frequenly share it with fellow riders. This pump is attached to my bike for all types of rides. When I park my bike at work or the gym, I can quickly unhook it and toss into my backpack. As a recreational rider, I don't think it's necessary to have a dial on your travel pump, but rather spend the extra dollars to purchase a nice homepump with dial. I agree with a previous review that the little muddle flap isn't the best quality, but unless you ride through an extensive amount of mud, it's not a big deal!

Rated 3 out of 5 by from It works It is a great size to fit in a small bag. I don't have braze-ons, so I typically put this pump in a little tool bag strapped to a rear rack, or put it in a messenger bag. It can pump road tires to about 100 psi without requiring too much strength. The combination Schrader/Presta connector is convenient and doesn't leak. The little mud flap is pretty much useless. You might as well cut it off. The way the handle locks down is a good concept (all the way in and twist slightly), but it tends to interfere with pumping a complete stroke. It is also difficult to find a comfortable position on the handle to push with power. Overall, it seems pretty durable, but it gets pretty warm when you pump quickly.

Rated 5 out of 5 by from Lightweight, works well I have carried this pump in my backpack for my 18 mi. commute the last three years. It gets used if I need to top up at work, or get a flat. As an "emerg" pump it is perfect. Yes the stroke is shorter than other pumps but it gets me up to 90 psi in no time and is totally worth the weight savings. Completely reliable & does both valve flavors (super easy to swap). Neither a bigger or a smaller pump would serve me any better. Insignificant complaint: The pump head plug doesn't stay in place.

Rated 4 out of 5 by from Great for emergeny use Because it's "single action" it requires a lot of pumps to get up to even moderate pressure, but pumping is reasonably easy. For "on the road" emergency use, this is a fine pump to get you back to moderate pressure and get you home. But keep a bigger pump and gauge at home for the majority of your tube work, especially for high pressure tires. And be sure to keep it set up for your valve type; it's hard to change it without resorting to long-nose pliers or similar tool.

Rated 5 out of 5 by from Excellent small and light pump. This pump is excellent! Easily attaches under the water bottle holder and does not interfere with your foot when pedaling. Nice sturdy construction for a small item at an affordable price point. Went out with it one time so far and sure enough had to pump up a flat. Was worried that it would be hard to pump but that was not the case at all. Was impressed with how easily it pumped (did not pump up to full 95 psi, just enough to make it home...guessing 70 psi). Definitely would buy again.

Rated 5 out of 5 by from Great! I already had a minipump, but I wanted one that I could fit directly onto the frame of my road bike. It fits nicely next to my water bottle. Fairly lightweight and does a better job than my other minipump: you get more pressure out of this pump and pump up the tube faster than you would expect. Perfect for on the road!

Rated 2 out of 5 by from Can Never Pump more than 60 psi with it I own and ride a mountain bike and a road bike. That's all I own for transportation. I was not very impressed with this pump. When having to use it on my road bike tubes I always reached a point where I couldn't add more than 70 psi in the tube. My road bike tires needed 110 psi. I like the idea of a having a pressure gauge. So I invested in a mini pump that comes with a pressure gauge although I am aware that it may be a little bit inaccurate but at least it goes up to 160psi, I am going to try it and will see if I am more satisfied with it's capacity.

Does this pump work on both Schrader and Presta? Some pumps do only one some do both. I would like confirmation either way before I order.... will look at other products.

Asked by: Kyle from South Park
Yes, the Pocket Master Blaster Pump will be compatible with both Schrader and Presta valves.

Does swapping between Schrader and Presta require unscrewing the connector and reversing it an screwing it back in?

Asked by: windblown
Yes, you will have to unscrew that cap and switch out the head on the Master Blaster when changing from Schrader to Presta.
