mini pumps are lousy to pump a tire up. all they can do is start the tube. anyone else have a pocket impero? I know angry likes his. can they really get a tube up to 80-90 without the pumper having a cardiac or arms fall off??

I've been using a Lezyne Pressure Drive for years, looks basically the same as this pump, and goes to 120psi (allegedly). It's great, hose screws onto the presta valve. Thanks to hose, no real risk of pushing too hard and snapping off a valve, although that's a risk I've only read about, never seen IRL. I use the pump holder attached next to my seat tube bottle cage, and it's never been an issue.

also, like R3awak3n, I am a frame pump fan boy. oh and I have ripped the valve stem off of a tube once, when using a frame pump. I was very new to cycling and it was my first time with a frame pump (a zefal hpx) so I had no idea that would happen. live and learn!

Little late seeing this subject but I'll put my two cents worth in.
Most mini pumps suck big time, they don't come anywhere near the claimed PSIs they say they can reach on the packaging with most only capable of reaching no more than 1/2 of their claims, and I've tried a bunch and sent a bunch back! The only mini pumps I have found that reach at least the pressure I want which is 100, is primarily the Lezyne Road Drive, SKS Wese Carbon, Topeak Race Rocket HP, HPX, and Road Morph G, and finally the Lezyne Road Drive large. The SKS Wese Carbon (which is no longer made, now SKS has nothing but junk? weird. I only mention it here because it's one of the few that will make it to 100 even in todays market). This gem of a pump is a direct connected pump unlike the others that use a hose, with any direct connected pump one has to be careful, especially at higher pressures, is the problem of people having the tendency to "saw" the pump back and forth as they pump which is bad for today's tubes since they have removed the reinforcement grommets that supported the stem onto the tube, so now tubes get ripped at the base of the stem if a person isn't a lot more careful than we once had to be, this is why more and more pumps are coming out with hoses because the hose will act as a shock buffer between the pump and the tube...assuming that the user allows enough slack in the hose for that buffer thing to work! But the SKS Wese does reach 100 psi and does so in about 300 strokes, this was the best pump in it's day when it was introduced about 15 years ago, no other pump back then could get to 100. This pump is very well built, it never has given me any issues in all those years. SKS since then has gone backwards in both capability and quality. The Topeak Race Rocket HP (I'm sure the HPX will as well and probably better than the HP but I didn't like the way it connected to the frame, I had to remove the water bottle cage and not use it because the pump took the place of the cage, stupid). This pump of the ones I'm mentioning as my favorites here is the least performing one, but it does get to 100 psi but only after about 400 strokes. Not badly built either, I've used mine now for about 8 years and it has yet to break. Topeak Race Rocket HPX (I never tried this one). This pump should be better than the HP due to the fact it's longer so less strokes will be required to get to 100. The build quality is the same since their related. But it only comes with what's called a inline bracket which requires the complete removal and discarding of a water bottle cage in order to attach it to a frame, that is just plain nuts; of course you can buy a side mount, note I said "buy", really Topeak? I have to pay extra for a bracket so as not to remove a water bottle cage? that should be included as standard with the pump! Not sure how many people would want a pump knowing they have to remove a water bottle cage. Topeak Road Morph G, is the easiest of all the pumps to use but not really a mini, I call it a 1/2 frame pump, and it doesn't fasten well to the frame as it moves around quite a bit as you ride. This fastening to the frame situation seems to be an ongoing issue with at least a couple of Topeak pumps, not sure why; this thing mounts using velcro, do I need to say anything else? Don't get me wrong, I love the pumps ease of use, but it keeps moving on the frame as I ride and have to constantly readjust it, strange design. But it operates like a dream, it basically converts into a mini floor pump with a pop out foot peg and a pop out T handle. It easily gets to 100 and then some in about 150 strokes, the least by a wide margin over any mini pump. One could actually use this pump as a floor pump instead of buying a floor pump. The psi gauge is not very accurate, mine is off by 5 psi, but once you know how far off it is you simply compensate. This is also the largest and heaviest of the pumps I'm mentioning, which is why I call it a 1/2 frame pump. I use this pump on my touring bike due to the larger tires which with a true mini would probably take 500 or so psi to get to 75, but with this pump I can do in about 125. And finally what I consider the best is the Lezyne Road Drive, however this pump comes in 3 sizes, if you want it to reach the 100 psi range and do so without a huge huge effort then get the largest size one, I seriously doubt the smaller will reach 100 psi, the medium one can but it takes a lot of pumping and I got tired as it neared about 350 strokes so I exchanged it for the large. The build quality is pretty good, no issues other than a plastic ring slips off but does not hinder performance, but I do have to keep putting it back on. This pump is only for Presta valves, no Schrader valves allowed. In my opinion it's the best looking pump as well. Again this is the best true mini pump I've used besides the SKS Wese Carbon, but the Road Drive takes a little less strokes than the Wese, the Road Drive takes about 250 strokes to get to 100. Now the subject of the Silca pumps. I've tried the Impero but not the Tattico, supposedly the Impero is the better of the two for high pressure road tires, but the Impero failed to get past 85 psi for me after about 350 strokes, so back to the store it went. The Tattico is not as well suited for high pressure as the Impero is thus I think someone will have a very difficult time getting it to just 75 psi based on what I found that the Impero can do. So with very limited use I cannot wax on about it's durability, but it failed in pumping so that was a total fail for me, the rest doesn't matter after that.

Comparable to original Silca?..
https://www.evanscycles.com/zefal-re...-pump-EV170488
It's plastic, cheap, requires some skill to pump (like the original Silca did) and therefore a poor seller in the US. :-) But it is lightweight, and capable of reaching high pressures with a reasonable number of strokes. I had one of these but (foolishly) sold it along with a bike. I might get one again.

Frame pumps were a necessity back prior to the mid 90's when tires didn't have good flat protection belts like they do today, so fixing a flat 2 or 3 times a week would have been a drag using mini pumps all the time, especially since the early ones couldn't reach 60 psi! Today I get maybe a flat every 6 months, last year I went the whole year without a flat, so on the rare occasion I have to use a mini pump it's not a big deal, but also a few modern minis, like the ones I mentioned earlier work good enough.

froze, you are amazing with all of this mini pump data. You mention you were inflating a touring tire with Road Morph G. Is your other data based on a touring tire, or something more standard these days like 700 x 25? Sorry to jump in so late, but I am working on a comparison of minis and this thread is excellent.

I've owned a lot of pumps which I mostly returned for exchange or refund because they failed to even get 75 psi with 23c size tires. The only pumps I kept out of the some dozen I tried are the ones I mentioned, Topeak Race Rocket HP (the other RaceRockets are smaller and will not reach their proclaimed 160psi), Topeak Road Morph G, the Lezyne Road Drive (large size only, the smaller ones will be more difficult and probably won't reach 100, the medium might but with a lot more pumping involved. The SKS Wese Race Day Carbon, I got that pump because I had a SKS Puro which was a really cool pump, it looked fantastic, and it had a built in PSI gauge, but the first time I used it I only got to 45 psi with a great deal of difficulty and then the pump literally blew apart from the strain of the pressure, SKS sent me the Wese Race Day Carbon pump as a warranty replacement! Free of charge! I still have that pump and it works great but sadly SKS no longer makes that pump, all their new pumps are trash. The one pump I have I didn't mention in my other post but did here in this post is the Lezyne Pressure Drive, I didn't mention that one in my other post because it's not designed for road tires and their higher pressures. I did however try to use it on a road tire just to see if it would but it won't go any higher than 80 psi which is more than I need for my touring bike. Normally I wouldn't recommend that pump but I got it as very good deal and it's only used in case of emergency if the Road Morph G by chance failed. I do find Lezyne products to be of very good quality. There is also a pump I didn't mention in either post because I hadn't used the pump when I wrote the first post, and that I do NOT own, but ran into a person that had one called the Zefal Air Profil LL, this is not a true mini however since it's about 12 inches long but it is shorter than the Road Morph G so really not that bad in size, but I did purposely let the air of my tire and used that pump to put air back in and I have to say it did so rather well, not as good as the Lezyne Road Drive large but darn near as good, and it's also well built. The only objection some people may have with it is that it doesn't have a hose, it's a direct connected pump which I know how to use properly because for years that's all there was, but the hose style minis are nice, anyway if used improperly a person may "saw" the pump while pumping and rip the valve stem base.

by the way, no mini, or even what I call the 1/2 frame pump Topeak Morph, that I know of can reach 160 psi like manufactures claim theirs will do. Leaving the larger Topeak Morph out and staying with just true mini pumps, the highest I ever could get the best one, which is the Lezyne Road Drive, was to 135 and I was dying toward the end. The good news is I don't know anyone who is running around using more than 120 psi on the street; maybe riding in a Velodrome I'm sure there are those that probably are running more but they use full size floor pumps to get to higher pressures.
Just keep in mind when buying a pump that the smaller the pump the less it weighs and the harder it is to pump and the ability to get to 100 psi is highly improbable since not even the Road Morph can get to 160 and the Road Morph is the most capable of the pumps to use. What I found weird, which I did this today due to this interest in mini pumps, is I went to You Tube and found all the videos on mini pumps being tested, and only ONE video was using a road bike that would typically need 100 to 110 psi, but all the rest instead used tires that need between 60 and 75! And that was it! The reviewers were too afraid to show the viewing public what they were going to be running into trying to get to 100 or 110!! The only video I found of a road bike being pumped up by a mini was using a Lezyne Road Drive but even that video quit filming at 120 strokes! And 120 strokes puts the Lezyne at around 45 psi.

Most bicycles today lack the pump peg and horizontal top tube that makes carrying a full sized frame pump practical; hence the mini pump. Pumps are limited to simple physics. The smaller the diameter of the barrel, the less force it takes to pump tires to high pressure. The longer the barrel, the less strokes required. Some pumps are double acting (pumps both on compression and extension), decreasing the number of strokes required. Anyone know of a pump that pushes more volume at low pressure and less at high so that you pump the tire up faster and you can achieve high pressure?
