Portland Design WorksShiny Object CO2 Inflator Head(Return to Product Page)

Even though I carry a frame pump, there are times when a CO2 inflator really helps: Instant pressure, no pumping. It's an "insurance policy" for me and it +a few CO2 cartridges will fit nicely in a small underseat bag.

It works as described. I had a flat yesterday and busted out the Shiny Object. I screwed in a CO2 and inflated the tire without the internals freezing up and with super control over the CO2 flow into the tire. There also a pressure relief hole so once you back out the cartridge it doesn't want to take off like a rocket. It slowly and safely bleeds off the excess CO2. Worth every penny.

bought this in Jan 2015 - Used 3 times. First use - worked as advertised. Second use - had difficulty with turn knob and burned 2 co2 cartridges to inflate tire. rd use - knob kept turning and never disbursed CO2 - never got my tire inflated. I went through another 2 cartridges and still had a mostly flat tire. Luckly a buddy had another inflator which worked by twisting the cartridge to engage rather than a knob which just spun (open or closed).

I have more than one of these because I like to keep one with me on each bike. It uses the screw in C02 canisters and allows user to regulate air flow, and to save some for later in the ride if the tire is still leaking.

I had a mountain bike tire with a bad tubeless valve, so I was able to refill it a couple of times in order to get me down the trail. They are metal and seem indestructible.

This is a really good, useful product.

Not unlike other all metal inflators this works good but gets so cold that I couldn't turn it off or get it off my tire even with gloves on

With valve can regulate co2 , if you don't use whole co2 cartridge you can close valve , save the rest

Works great! You can really control the air release. No more wasted cartridges.

This is a really good inflator. The valve on the top really lets one regulate the flow of the CO2 gas into the tube, and if for some reason it's leaking around the valve you can cut off the flow quickly.

This is far and away the best CO2 inflator I've used. Extremely light and compact, yet also extremely well-designed and durable. The wheel allows you to reliably control the onslaught of CO2 into your tire perfectly, and the simple T design positions the cartridge in a way that's easy to hold and get the inflator on and off the valve stem without a fuss. Can't ask for anything more.

Works great, small, and light. Much better than the Lezyne POS that failed when I needed it.

Very easy to use, easy to control how much air goes into tire. Leftover CO2 does not leak away even days later. Highly recommend.

The best inflator I've ever owned. No nonsense and easy to use. Your ability to control the flow of air is precise and make it a must have tool.

I already have this adapter, but needed another. It works great and there was no need to look for something else!

The product is advertised as pretty, compact, durable, and easy to use. Personally, I care less how pretty it is. Compact is somewhat important, but durability and ease of use are the key requirements. The first time I used it I thought it was easy to use. But the second time I used it (fixing my daughter's flat) it came apart and I have not been able to put it together. So save your money and get something less pretty that holds up to the demands of pressurizing a tire.

I got these to replace a co2 inflator that failed after years of service. I prefer an inflator that screws securely the presta Valve. But after using this one. It's not bad at all. Just hold on to valve and open the valve. Couldn't be simpler. I like the adjustable valve. You can just give a small shot to locate puncture it tube without dumping the co2 charge. With this co2 inflator I found it easier to locate, patch , replace the tube on one 16 g co2. It took a few times for me. But I can patch a tube now on one co2 in under 3 min.

Two needs for this sort of product bc 99% of the time you dont need it - that it works and its small. This product wins on both criteria.

Used only once and it worked great. Fits really well in my under-the-seat bag.

Solid design, durable and no problem inflating my tire.

If you use CO2, this is a great device - compact and light weight.
