Granite Punk CO2 Inflator Review

In this review, we will be taking a close look at the Punk CO2 Inflator from Granite Design. This small Inflator uses a CO2 canister to inflate your tyre.

It works with 16g and 25g CO2 canisters and weighs 25g. Its small form factor makes it easy to fit in any bag, pocket or even on your bike using one of our One Track Mind Skull Enduro Frame Straps (in-store now woo!)

Never mind the punctures, here’s the new Granite Punk CO2 inflator!

The Punk CO2 Inflator is a really small form factor tyre inflator. It comes with a sleeve that not only protects your podgy fingers from the canister when in use (CO2 Canisters get really cold really fast when in use) but it also has a belt sleeve so you can attach it to things like a frame strap.

It also has a small plastic spacer so you can keep the inflator tightly screwed onto the canister without puncturing the canister seal. In theory, this is to stop you losing the inflator out on the trails but I did notice mine came loose once so I ended up just keeping it in my pocket.

As per usual I didn’t read the instructions and I didn’t take them with me either. I expected this inflator to behave like my others where you screw the canister into the inflator until you break the seal and then using a button to let the gas escape from the canister into your tyre. This product however doesn’t have a button, you need to first put the inflator onto the valve and then screw the canister into the inflator. My first attempt I wasted a canister but quickly I realised how it worked and it worked well when used properly.

Price-wise this Granite Design inflator is on the higher end. Doing a quick google search you can find many for around £4. There are a few around £20-£30 mark but these feature knobs and buttons allowing you to control the flow of the gas.


So, in summary, the Granite Punk CO2 Inflator is a nicely made little product that takes up very little room and can easily be mounted onto your bike using a frame strap or easily stored in your pocket or bag.

The tool is certainly on the pricey side for what it is, so make sure its securely tightly. It doesn’t have any buttons or knobs to control inflation. You do this by simply turning the canister which makes total sense when you think it’s a single-use product, why overcomplicate something that is essentially only on or off.

My personal thoughts on CO2 Canisters, in general, are that they are quite wasteful. They are single-use and you can buy a decent mini pump for a similar price which is reusable. Canisters certainly have their place still. For example when racing enduro and you need to get the tyre inflated ASA-Freekin-P! Or perhaps you need to seat your tubeless tyre out on the trail.

Have you tried the Punk CO2 Inflator from Granite Design? What are your thoughts? Perhaps you’ve tried a different CO2 Inflator? Let us know in the comments below or add your own review.

3.5 / 5 Reviewer
Small Form Factor, Nicely made, Works well.
Pricey, Inflator can come loose from the canister when riding if not tightly secured in place.
A well made, small form factor tyre inflator that does the job well when used correctly. It is on the pricey side and doesn't include any knobs or buttons to control the inflation.
