Air Support
 

Any recommendations for a hand pump (on the road use), not a floor pump. I have two very old pumps, one is a Topeak mini pump that works ok, but it takes about 200 pumps before I can even get about 50psi on the tire. And my other pump is total sh*t. It's a Bontrager Airsupport I don't think it could even get up to 50 psi.

Believe it or not, I've been blessed over the past few years by having my tires go flat once I got home. I can't remember the last time I had to repair a flat on the road, it's been years and that's why I haven't really looked for a pump, but I just get the feeling that my luck may be running out and I want good pressure on my tire if I have to do a road repair.

I ride about with a 700 x 35 (Presta valve) and charge the tire to about 75 psi.

BTW, has anyone heard of KuJo inner tube? I saw them in one of my LBS'






.

Get the full size Topeak Road Morph. That will work better than the mini version

Maybe use your pump to get the bead seated straight, partially inflated etc. and then hit it with CO2 cartridges?

Lezyne Pocket Drive

There’s a Pro version too. Not tried it.

This hand pump works great. You twist a fitting on the barrel to switch between high volume (for getting air in quickly at first) and low volume (for lower effort when the tire is nearing full pressure) per pumping stroke. The link below is to an Amazon listing, but you can also buy it on the Crank Brothers website..

Look at the High-Volume mini pumps. HV as opposed to High-Pressure pushes more air per stroke but can only achieve up to 50-80psi where the HP can go to 100+psi. Most manufacturers make both versions and you will have to check their psi ratings. Lezyene, Topeak, CrankBros all make good pumps. Personally, I like the pumps that have a pull out hose rather than a rigid pump head as it helps prevent tearing the valve stem when moving the pump around while pumping.

This ^^.
And if there is a flip-out flap to place your foot on, it's basically a floor pump. The Topeak "Road Morph" is one of these, and also has an in-line gauge which is very helpful. I've gotten tires up to 115 psi easily and without ripping off the valve.

+1 on the Road Morph, especially with the inline gauge. I've used Zefals, Silcas, and many others, but after getting the Road Morph, it's become by far the favorite on-bike pump.

Barrel diameter can greatly affect application and usability. A larger-diameter "high-volume" pump can fill a tube/tire fast, but require superhuman strength to go above 50 psi / 3.5 atm. Smaller-diameter pumps are easier, but as noted above can take eleventyzillion strokes to get to rated pressure. If you can, try before you buy. Or just get a Road Morph. :)

Oops I meant Alloy Drive. Just checked mine.

See post 5. Switchable between high volume and low volume.

fwiw, once I tried a cartridge inflator, I was sold. I carry a small pump too for "just in case"

My best pump has been a Bontrager small floor pump with a clamp on head. Now discontinued. WTF. Way better than a screw on one.
What does happen is the screw on cap comes LOOSE. Simple fix. That's why it won't then do high pressure and takes longer.
Inside there's just an O ring with no lube.
Holding those other hand held pumps flailing in the air 150 strokes is NUTS.

I got a generic mini battery powered pump that works surprisingly well. Slower than a floor pump but much faster than the frame pumps I've used. A bit heavy, but worth it. Inflates to a pre-set value which is nice.

I've had good luck with the Lezyne Road Drive. 120 strokes to 80 psi in a 28 mm tire.

That's way too high. It should be more like 50psi at that width. Look up the Silca tire pressure calculator.

Hell no to 50 psi. Not even good enough for my 650B x 38.
64 to 70 is what my 700 x 35 have been. I fill the rear to 72 often.

Recently I bought two mini pumps from Amazon: Giyo GM043, and Kardne mini pump
The Giyo pump is small, but it telescopes out in two sections, so the pumping volume is a lot more than you'd think. Unlike a lot of other mini pumps with screw-on pump heads (which tend to unscrew the valve core when you try to unscrew the pump head), this Giyo pump has a lever lock pump head. It's just a great little pump that works well. Highly recommended.
The Kardne pump comes with a screw-on pump head which has a tendency to leak if you move around even slightly. Luckily it can be easily replaced with a SKS Presta adapter (also sold by Amazon) which is push-on. With the SKS adapter, this pump is pretty awesome.

Kardne pump and hose with SKS push-on head

I pumped up a 700x25 and a 26x2.1 tire as a test and it sure worked. It takes a lot of strokes but for something I only use twice a year it's perfectly fine. It's also the smallest pump out there. I returned the Giyo and kept this one.
Oh yeah- the flexible hoses on these pumps seem convenient, but they add restriction to the airflow and lead to higher pumping effort. Luckily the Kardne pump lets you leave out the hose and connect the pump head directly to the pump itself.

Old school
 

Silca impero frame pump. Pressure and volume. Doubles as a self defense weapon. As far as weight goes, it'll lighten your wallet enough to offset the bulk.

I hope someone starts making the Zephal HP/HPX again or a very similar pump/ Patents had to have expired long ago so I cannot see any reason not to copy them exactly. Those pumps worked. Really, really well. I lent mine to a skinny 40 yo engineer at a time trial 50 years ago and he had no trouble inflating both tires to 120 psi.

100 not so hard strokes to get to full riding pressure. I raced on air from my HP for nearly all my races; inflating near flat latex tubed sewups. THe HPX was a little quicker pumping, same effort. (The handle twisted to bypass the spring to secure the pump when it was mounted on the bike; making the stroke easier. Zephal then made the barrel a touch larger. But that did made for one more part that could fail. So I basically consider it a draw as to which model was better.

No hose. But wrapping your hand around the head, the rim and tire and perhaps a spoke or two was easy and meant all pumping force was opposed by your hand. And made on-off very fast.

Their pumps do work well . 👍
This one is way lighter than my Silca, but makes a bit of noise going down the road.
I tested mine the other day and from dead flat to 50 lbs was about 60 strokes. https://cimg0.ibsrv.net/gimg/bikefor...55f7717a34.jpg

I have a cheap Schwinn-branded mini pump that came with a bike I bought used, with gauge, and it has both the hose and flipout lever (by rotating the pump end on a 45 degree axis, clever), and yeah, can use two hands on the flipout T handle on the pump shaft.

I may look into that, good price.

The PREVIOUS version of the Crank Brothers mini pump, I saw at a used sporting goods store, looked like new, all metal, two pump heads and rotate the barrel to select which one, gauge, switchable for high volume or high pressure, looked quality construction and design! Tried it out on my bike then and there... Even on high volume, would take 10-15 minutes of steady hard pumping by my guess to pump up my 20x1.75 up to like 60 PSI. Incredibly slow. Looked up review online, said same thing. Explained why it was like new. Sounds like they fixed that. A gauge would be nice. So would a double head, but I can switch the innard if need be.

EDIT: For long frame mount pump, Zefal HPX in the correct length for your bike, it's the original with the handle that locks out the spring.

Silca radically changed the design, I guess. That doesn't look like the old-school Impero.

Fond memories of people accidentally tilting an Impero slightly sideways after inflating a tire and watching the handle blow out of the pump body and sail across the street.

I have the Silca Tattico on both my bikes, it works very well. I’m usually the guy that fixes flats on group rides, for some reason I enjoy it. It also gets me beers at the end of 5he day.
