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

I have not using it yet, but it should work the same with the non-threaded CO2 case. It is should be lighter and easy to use.

This is awesome, you get to regulate the amount of CO2 used and how fast or slow.No more losing all your CO2.

The Portland Design CO2 Inflator works great. I really like that it has an adjustable air release valve. You can slowly fill the tire with a lot of control. Just a great product.

Finally had to use this in anger the weekend and I was pleasantly surprised. More controllable than I had thought it would be. THe valve is smooth and you will be able to let in just a little or a lot with ease. Stores in a tiny space. My fizik bag easily holds this, two cylinders (16grams), a tube, multitool, and spoke wrench. even if I get picky I cant find any issue with this at all.

This product works great so far. I (knock on wood) have only used it a couple of times. The adjustable pressure valve makes it easy to put the C02 into the tube. It is mostly metal, so I anticipate it lasting.

I received two back to back flat tires in the beginning of an 75 mile ride to Piermont and back earlier this week. This tool definitely came in handy. It is compact and easily fits in a saddle pouch or jersey pocket. It is made of quality materials and I love the fact that you can vary how much CO2 is being released via the vale. The changed tires were inflated in seconds and I was on my may. Funny enough, one of my riding buddies suffered a flat on the way back (on the same trip). It was my first time using the tool and I had the opportunity to use it 3 times in one day. All in all, well worth the money.

The Portland Design CO2 Inflator works very well. The CO2 canisters for this devise thread into it on one end and it has an adjustable air release valve. I really like that you can slowly fill the tire with a lot of control. The Inflator itself is very small and light and easy to carry. Just a great product.

On the road in a pinch (pun intended) I like the controlled CO2 release.

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.

My rear tire lost air eight miles into a ride, so I had an opportunity to use the Shiny Object. I was really impressed by the control the device afforded. Got the tire re-inflated to the exact point I wanted, and got home without more drama. I think the control the head offers is well worth the price.

I have two of these, one for each bike. Super easy to control the inflation rate with the open/close valve knob.

This is a solid light weight inflator to keep in your bike bag. I used to have a pump on my downtube for my CO2 cartridges. This was easy to use when I needed it to inflate a tire after a blowout.

What a great product. Rugged, yet small and light. Allows one to gradually add flow from CO2 cartridge to a deflated tire eliminating risk of over inflation. I�ve tried other CO2 cartridge inflators. Hands down, this is the best.

This inflator is an improvement over my old one - it does all the old one did at a tiny fraction of the size. I was using an enclosed-cartridge inflator that used cheaper threadless CO2 cartridges. I realized at 2-3 flats per YEAR, the savings weren't worth carrying my old bulky inflator.

Haven't *needed* to use this inflator yet, but like all ride-critical tools, I home tested it, "wasting" one cartridge. It worked just fine. The valve on the inflator was easy to operate. The cartridge DOES get seriously (dangerously?) cold, but wrapping it in a cycling glove solves that problem.

I got this for my MTB and I haven�t needed to use it, but it looks solid.

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 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.

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