Pro Bicycle Frame Pump

I have had this pump for several weeks and I use it to inflate the tires on my wheelchair. This is a very durable pump and it's double action cuts the effort in half. I was also impressed to find that there is an air pressure guage built into the pump, so if you need to know the psi you will be quite pleased with this product.

Almost useless

not as easy to pumo to 100psi as i tought it would be from other reviews, not easy to read the gauge. but it works ok!

I own this pump since 2009, and while it is relatively easy to fill up to say 85-90 psi, I seem to be bending my valves every time I use this pump. I've never used any other mini pumps so I cannot comment how it compares to the alternatives out there in terms of ease of pumping, but I believe a flexible hose like the Lezyne and the newer Topeaks have may be useful.I've found the integrated pressure gauge to work best when the pump is at an angle of 45 degrees or more (chuck side down).Only once had I have a problem with the valve sticking to the pump and pulling out with the chuck, but I think it was more of an issue of valve working loose from the valve stem. It fits into my medium size Topeak Wedge seat bag easily.As it is the case with many mini pumps without a flexible hose, it works best if you lay your wheel flat, rest the chuck on a hard surface and pump, using your dormant hand to stabilize the wheel/pump instead of holding on to dear life pumping the air "against" your hand, if you know what I mean.

I've had the this pump for about a month and have had the honor of having 5 flats in that time (3 in one trip). I've found this pump to be a complete failure.In all cases I've never been able to get the pressure high enough in my tires (about 65lbs - 26" mountain bike rims) to consider the tire fully inflated. I've had trouble getting the pump to make a tight seal against my shrader valve type stems - losing air that I'm pumping in.Additionally the general design of the pump means the stem is getting pushed and pulled while I pump, in 2 cases I ended up damaging the valve stem to the point where the patched tube was worthless.Finally the little chrome decoration in the middle tends to come lose while pumping and get in the way; it's just a decoration anyway - it could be left off.Overall I think the pump is a failure and I will be tossing it in the trash. In the future I'll be looking for a pump with a separate screw on type hose that I know will make a good seal and will minimize the trauma to the stem while pumping.

The best alternative to carrying a full size pump. Fits in your jersey pocket, built like a tank, and can reach 120 psi easily. I've had he Crank Bros. and this is easily the better pump. While heavier, it is made to last.

bottom line: with a few tweaks this would be the best pump on the market by a massive margin. As it stands it is a barely usable waste of brilliant engineering; and as an engineer that makes me sad.This is the only bike pump that I have seen which uses genuine 2 stage compression. The push stroke puts air from the telescoping chamber in to a smaller chamber in the pump, the pull stroke forces that air in to the tire. This makes for a drastic improvement in both pumping efficiency and force needed to pump.Unfortunately it is poorly made. The worst part is the gauge. It does not work; and because the pump is more efficient than expected it caused me to over pressure and blow up a tire. (on the good side this proved the pump is capable of going well over 110 psi) The valve connection is nowhere near as effective as that on similar pumps, and because you need force on both push and pull it is harder to keep it from damaging your stem. I could rant about weight and material selection too, but that is just a matter of needing a higher end model. Also I do not trust the holder it comes with at all.If I were making it I would use a short hose with a screw in connection, an adjustable poppet pressure relief valve instead of a gauge (Why does no one do this?!?) and make it with aluminum and carbon tubes to get the weight down. To Quicker: One more product iteration please! you are so close! to all the other bike accessory manufactures out there: Please obtain this IP and start using it!

I bought this pump from my LBS to have a smaller pump to carry, one that I can easily toss in a pannier. Most frame pumps are long enough to make this difficult. I've used it once, on both tires, to make sure I could work it.Like all frame pumps, it's designed for someone with much stronger arms than me, an issue exacerbated by having to hold it with both arms rather than against the ground and with the fingers of one hand gripping spokes and the valve end of the pump. I had to be careful how I held the valve end, or it slipped off. I managed to get 65 PSI into my road tires, enough to get me home safely but only 2/3 of what I'd like the pressure to be. I get few enough flats that this is usable, though barely, as long as I'm careful to avoid hitting bumpy things. That's about as much pressure as I can get with most frame pumps, a little less than I can get with the one I've had which has a hose and can be pushed against the ground. So 3 stars represents the maximum I'll give to any frame pump I've seen yet. And it's fairly costly.I found the built-in pressure gauge to be useless, as I could not read it while pumping. Even if I could see it, it's so small that the accuracy is necessarily poor. And the numbers are bizarre, not multiples of 10 PSI -- I think they are multiples of 2 bars converted to PSI. That's just silly.Why oh why doesn't someone make a frame pump (or even a floor pump) with a screw-end for Schrader valves so you don't have to hold it against the spokes, a short hose to keep the pumping action from pushing the valve around, a useful pressure gauge or pressure relief valve, and a mechanism designed to require more strokes at less force, for those of us who aren't wrestlers but just bike tourists? That isn't rocket science, but it is needed to persuade me to rate a frame pump above 3 stars.
