Portland Design Works Shiny Object CO2 Inflator Head

It's sturdy, lightweight and compact. It is easy to control the airflow with the knob.

I bought this because my previous inflator did not work for me. I normally have used a frame pump for my tubed tires, for years and years. My newest bike, I made the transition to tubeless tires. Also, I didnt feel a frame pump was proper for use on this bike, so I switched to CO2. I threw an o,d inflator that Id had for years into my seatbag. First time I needed it, it didnt work. I ordered the Shiny Object head as soon as I got home, mostly because of the reviews I read on BTD, and they had a great sale price. Ive only needed to use it once so far, but it was so easy and worked perfectly. I am very happy with this purchase. Thanks BTD and PDW.

I haven't used it and hope I don't have to. The real test will be if it works when I need it or will it be unusable because I didn't use it and now the knob won't turn cuz it's gummed up with mystery funk.

I've tried a bunch of these over the years. Some look good, but break quickly. This one is small, simple and tough. It works when you need it.

With the Shiny object you can easily dial in the amount of co2 you want to put into a tire. Great for checking to make sure you don't have any tube pinched under the bead. Then let it rip and fill the tire.

I have 2 of these and using them could not be easier. Fast and light.

The Shiny Object is an easy to use device that attaches to a threaded CO2 cartridge for the purpose of inflating a tire. The dial allows the user to control the amount of CO2 released instead of the all-or-none release of some similar units. It's small and easy to carry in a seat bag along with the CO2 cartridges instead of having to carry a pump along on the ride. There is no pressure gauge on the unit, however, so the user must estimate the desired pressure.

Its small, so its easy to carry in a seat bag. The valve it perfect for modulating your inflation. The small simple device works perfectly and is exactly what you'd want for road side repair work.

This is simple, small and reliable. Well designed!

Having control of air flow is what it is about! Slow or fast inflation is crucial, and this Shiny object allows this.

This Portland Design Works inflator is so easy to use it makes me want to have a flat tire!

This can be throttled to a minimal flow for gentle control of inflation.

This is the only valve I've ever used that actually holds pressure after it's pierced the C02 cylinder. I've used the partial pressure after a couple of months of initial use. I use it and several friends use them as well, all have had the same good luck with these valves.

Great product easy and fast

When you need one of these you need it to work simply, reliably, and with some control. You get all of that with the PDW shiny object CO2 head. If you don't want to worry with carrying the little leather sleeve in your flat kit or saddle bag just use an old inner tube cut to length as a sleeve. This will keep you from freezing your hand. The dial allows you to control the flow of air so that you don't just blow the new tube or pinch flat straightaway. This is the standard for CO2 heads as far as I'm concerned. Get two!

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).

Nice and compact. Great design. Fortunately I havent needed to use it.

Used ut a couole of times,and then the rubber gasket blew apart and i havent been able to get it to stay put to use the inflator again.

I've had this inflator for over two years now. Looks like it's been to hell and back, because it has, yet still performs flawlessly no matter how beat up it gets. It's the most straightforward, easy to use design out there, it's simple and incredibly durable, and it's super light. There's no reason to even consider a different inflator. Came back to pickup a new one as a backup so I don't have to always remember to swap one between bike bags... because I doubt the older one will ever die.
