EyezOff Airbone ZT702 Supernova Ultra-Compact Bicycle Pump for Schrader/Presta (9.9cm) Silver

Fantastic as an emergency pump as it fits into a saddle pack. I have tested it with a tube and it does pump OK. That said, it would take a fair bit of pumping to inflate a road tyre to 100PSI so I also carry a CO2 cannister.

Takes hundreds of strokes to pump a tyre to a useful pressure, but I only wanted it because it is tiny. It IS tiny and as a emergency get-you-home pump it is fine. It is not lighter than the lightest larger pump, (by few g) but its small size means it easily fits in my micro seat pack. Like it.

An excellent compact pump. The only gripe is that the presta valve has to be screwed on and sticks out a mile.

Arrivata oggi, all'interno della sua confezione originale (oltre che a quella di Amazon) e sembra di buona qualità. Spero di non adoperarla mai, ma nel caso spero faccia il suo sporco lavoro.

Si inserisce facilmente nella finta borraccia ed è valida per portare la ruota da corsa sino a 5atmosfere permettendo di rientrare in sicurezza.

Micro pompe de bonne fabrication mais qui pour moi sera un bon complément a une cartouche co2. Le scratch de fixation est absent du colis donc la photo de l'article ne correspond pas.

Sino quieres cargar con infladores grandes, este modelo es el tuyo ya que apenas tiene 12 cm. La única pega pero para mí no es importante, es que tardarás algo más en inflar las ruedas. Cumple con los plazos de envío.

Realmente pequeña, no ocupa nada. Eso sí, veremos cuando haya que usarla, imagino que habrá que darle duro a la manivela ;-)

This little thing looks like a toy or a novelty. It isn't! It's a very functional pump in a sub-miniature package. At a casual glance, one might mistake it for a CO2 inflator. It's small enough to fit in the smallest of seat wedgies or can be pocketed or mounted with the included frame clip. You could even carry it in your sock without looking too silly. The pump alone fits schrader valves and comes with a brass presta adapter of the same type that any bike shop will sell for under a dollar. So let's get down to it.The brass tacks: After unboxing, I snagged the front wheel off the nearest road bike and deflated it fully, installed the presta adapter, and threaded on the pump. Inflating a 700x23 tire to a get-me-home pressure, probably around 80-90psi, took 300 strokes. Compare that to about 100 strokes with a much larger, heavier, won't fit in the wedge, much more difficult to operate, leaves my arms tired, dual action "mini" pump. The same process repeated with a 27.5x2.2" mountain tire took 600 strokes to get to around 50 pounds. Rideable pressure in both cases, your tires may vary. The strokes are easy even at higher pressure thanks to the small bore so don't count on escaping your upper body workout just because you had a puncture. If you find you need to rest mid-inflation, simply let go. Once installed on the valve, the pump is very secure and since it weighs next to nothing you can safely let it hang.A bit of numberating shows that each stroke delivers all of 12cc, most of a tablespoon, of air and even less as pressure increases (physics stuff). So it should come as no surprise that a pump this size takes a lot of pumping to get back on the road. But you WILL be back on the road and while larger pumps deliver more air, they are also more difficult to pump so the additional strokes may not necessarily mean more time on the curb.The gory details: Delivered packaging was as shown. Package contents were the pump, presta adapter, mounting clip, and a pair of cap screws to mount the mount to your mount. Not included in my package but shown in the description photo were a velcro strap and nylon zip tie. I didn't miss them until coming back to write this review and saw the photo. Honestly, I don't know why you'd need either. The standard velcro strap is unnecessary as the clip holds quite firmly already and the design makes it impossible for the pump to slip off the end. The zip tie? Maybe for theft prevention I guess but you're going to have to cut if off the first time you use the pump. Not sure what else it could be for. I don't plan to use the mounting clip at all. This pump will tuck in the wedge pack alongside tools, tube, tube patches and flesh patches. I'll be glad to get rid of the pump from under my water bottle. It just hangs out the side there, looks ugly and is really just a drag.I plan on getting a couple more of these. Maybe even a couple more than that. At this price and size, there's no reason not to have one on every bike in the stable.

Extremely compact and I love the screw-on valve stem feature - I wish all pumps had that. Seems very well-engineered and durable Yeah, I'm lucky to get my tire to 50 psi after 500 strokes. But that's enough to get me down the road to find some real air. Don't rely on it as your main air pump. Rather, it's to get you back on the road when you're out in the middle of nowhere. And the 99.99% of the time that you're not using it, it packs very easily either on the frame clip or in your pannier. Don't forget to put a little oil on the pump shaft every now and then. If you want the smallest possible pump that will save your butt in an emergency, this is it.

This little pump is just great! I have spent more for cheap bicycle pumps at the bike store before, and those always have a problem with clamping down on the Schraeder valve. This one solves that problem with a screw-on tip! Simple and brilliant. It also seems to push quite a bit of air for its small size. Very happy with this purchase.

Very good product. I like how you can lock in a ball needle, and how durable this thing is. It seems very well designed and well made. Does take some work to inflate most items, but that's to be expected since it's so small. I would recommend this product.

Works well as our stroller and soccer ball pump. Very compact, but that doesn't diminish its performance.

Better than specMini sizeLovedI will buy for good gift to my friends

Had it for years,many of them. Small,strong and reliable. Even if tiny small, once secured on the valve (schrader is a great connection to secure it on) pumping is easy starting only by a wrist movement.

Lots of strokes but it'll pump up your tire.

A very compact pump that fits in the smallest saddle bag for emergencies. I love it!

good deal
