Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Zefal Mini Pumps

Air Profil Micro, Air Profil XL, Air Profil FC02...any users here of any of these? Are they good road bike mini pumps to bring on long rides? Would like to hear some personal experiences if theyíre durable and capable of getting good enough tire pressure in case of flats. Iíve checked online and seen only a few reviews on these, mostly on the Micro. The Air Profil FC03 got good reviews, but it is not currently available where iím from.

I have a Topeak Race rocket mini pump and have had to use it 2-3 times. Takes about 150 strokes to get a 25 tire up to pressure but for once every year or two, I'm good with that. No reliability issues so far. It has a short retractable hose, which is much easier to use than the ones that screw directly to the valve.

I haven't used any of the specific models in question, but I don't think that any pump manufacturer is working with significantly different tech/physics - in other words, they all suck.

Like Ogsarg, I think that models with hoses are much easier to use - all of these mini-pumps are going to require significant force when you're getting to the higher PSIs and having the hose gives you some fudge-factor so that it's harder to inadvertently rip off your valve stem as you furiously pump away.

The Profil FC02 looks much like the Lezyne mini-pump that I have, though it extends further - that might cut down on the number of strokes, but it's still going to have the same basic limitations. I mean, it works, but it takes some time and effort. Also, because the straight handle can dig in to your palm, if/when I buy another mini-pump, a rotating, T-type handle would be high on the priority list.

Having a little fold out stand/toe clip would be nice, too, so that you can push against the ground rather than solely relying on your arms, but this will usually increase the size a bit. If I were still running tubes, this feature would be pretty important, but because I'd use it so infrequently, a smaller form factor might be more appealing.

I recommend a mini-pump with a flexible hose that screws on to the valve (like the Air Profil FC02). The flexible hose allows you to position the pump for the most comfort.

Pumping is all physics as you say. For a road bike/high pressure you should get a long but slim pump, like a Racerocket HPX, or what ever similar model other manufacturers carry. Much better than a short, thick model.

One thing that worries me though is the valve core getting accidentally removed by these screw-on type heads, though iíve read you can tighten valves with pliers. All the mini pump iíve used were those thumb lever types. These Zefal pumps are my first options coz theyíre readily available where iím from. There are some i can buy online locally, the Fabric Nanobar and the Birzman Swift, both with hoses. Thereís also some from Park Tool, Pocket Protector, the Half Pint Mini but i think thatís like 10.5 or 11 inches long and only has 90 psi max. Both have foldable handles. I was looking for the Topeak Micro Rocket but thereís none here, buying it from ebay or amazon means double the price with the shipping so thatís not an option for me. Lezynes are too pricey for me.

Right now, itís any of those Zefal pumps, Fabric Nanobar, or Birzman Swift. Birzman Swift looks nice and durable.

No Racerocket HPX available here, none from all my searches. If only thereís a Zefal HPX, iíd get it.

I use this one, the standard Air Profil. I've used the same one for 6 years on my commuter mountain bike. Zero issues with durability and reliability. Works perfect every time, no leaking air, no problems. It takes a lot of pumping to fill a tire. I had never used it on a road bike tire until this week. 6 year old pump, stored on my bike, and it aired up two 700x25 tires to 90 psi just fine, albeit with a whole lot of pumping. It says it is rated to 116 psi, I think that would be very difficult to make happen.

Zefal HPX is a frame pump, not a mini. Race rocket HPX is from Topeak. Its a mini that can sit by the bottle cage. Im sure you can find a store that will ship to where ever you are.

Wow, i wish all mini pumps are that durable. That looks exactly like the XL, same length too, except that the XL is telescopic and says it can do up to 130 psi. One thing that worries me abt the XL is itís durability. I read a review, i think itís on roadcc, that thereís already some play after just a few uses.

Found a Lezyne Pressure Drive(small) and Topeak Racerocket HP available online locally. Iíll just get one of those two. Anyway, i emailed Zefal and hereís what they said:

ď The FC02 has a 18mm piston diameter (the same as Air Profil Micro and XL). Depending on your strength, it may be enough to inflate to 6~7 bar (with equivalent diameter, the pumps with flexible hoses may be a bit harder at high pressures than direct connection ones).Ē

Ditto, the Topeak Race Rocket HP. I've had one for about 3 years and have used it often on four bikes, including my hybrids. The ergonomics are very good, soft grips, rounded ends, flexible hose, smooth pumping. Sure seems durable. And versatile, with a convertible screw-on chuck for Presta or Schrader. Costs around $25 and a bargain at that price.

The longer HPX might be a bit better but the HP fits in any pocket. The main improvement might be a better valve core tool. The tool that came with mine is soft plastic, useless.

The Blackburn Core Slim is also good. It's longer like the Topeak Race Rocket HPX, and needs somewhat fewer pumps to fill a high pressure road bike tire. Presta only. Has a useful metal valve core tool. Mostly comparable to the Topeak Race Rocket HP but with mediocre ergonomics. No rubber grip, and the ends are hard with sharp edges. That stuff matters after about 75-100 strokes when pumping pressure gets more difficult. I paid only $15 for the Blackburn so I have no real complaints -- it was a dealer sample, but unused, still in original packaging. I guess the shop decided to stick with Topeak.

I tried the Lezyne mini-pumps but some models seemed fussy to assemble. The ergonomics were about the same as the Blackburn -- hard ends, sharp edges, not much to grip. Prettier, maybe, but the Topeak is easier to actually use.

Regarding threaded chucks messing up valve cores, that's happened maybe once. I had a slow leak on a hybrid with Schrader valve tubes. Couldn't figure it out but a mechanic at the LBS spotted the problem right away. But I don't know for sure that the threaded chucks on my mini-pumps were at fault. I typically use my Nashbar floor pump with clamp-on chuck at home. This was a new tube, so I doubt I'd have used the mini-pump on it when that slow leak occurred.

Since then I try to remember to tighten valve cores on new tubes before installing them.

The valve core issues are, I think, mostly a problem with the screw-on hoses that don't have an air bleed (I assume that the pressure inside the hose is pressing the hose/valve core threads together with enough force that the valve core unscrews from the stem, instead). My Lezyne has unscrewed cores on me a few times - it's really deflating (har har) when it happens because you've just spent the time and effort to get the damn tire up to pressure and now you're got to start over. In any event, it was problematic enough that Lezyne introduced the new hoses with an air bleed button.

I have had a Topeak Micro Carbon Rocket pump for years. It works great but you do have to maintain great position and posture while using it and it will only get you to 65-75 psi then you need a bike shop top off or something to get you to your proper psi (for me it's 90/85) My next jersey pocket pump will be a Lezyne Carbon Road drive with hose.Higher psi with less strokes and a hose for better ergonomics.

The air bleed and the integrated valve core tool is what makes me lean toward the Lezyne Pressure Drive despite it being smaller at 170mm. If only the valve core tool of Race Rocket HP is useful though, i would choose it coz itís a bit bigger and i like its looks better. In terms of peeformance, according to reviews iíve read, theyíre both good. So i guess you canít go wrong with either. Anyone knows the Race Rocketís pistonís diameter? Pressure Drive is 17mm for medium, 20mm for small.

Settled with Lezyne Pressure Drive. Ticked off all the boxes except one. I thought mine has the integrated valve core tool, this is what sold me to buy this over the Topeak RaceRocket HP. It didnít, so a bit disappointed. Still, very satisfied as the Pressure Drive has air bleed, looks very durable, is reliable and is a great looking piece of tool. I got the small blue one.
