CO2 vs. Hand Pump?

It doesn’t matter if you’re a dedicated roadie, mountain biker, ‘cross racer, or all-around, pure bred race machine, this debate seems to be relatively universal: should you use CO2 or a hand pump? As with all great debates, there are pros and cons to both sides, so the most helpful piece of information becomes context. Context, meaning, are you a racer? Do you ride double centuries frequently? What exactly does your average ride look like and where does it take you? After inspecting those things and understanding your place in the grander cycling context, we can then begin to make educated decisions on what best suits your needs.

One thing to be mindful of, regardless of whether you choose to run a CO2 system or a hand pump, is that both are rendered absolutely useless without something to inflate, so whether you’re running tubeless or not, it’s always important to have the proper patch kit and/or spare tubes handy to allow you to actually fix your problem. So now that I’ve cleared that up, let’s delve in further.


If you are a road or XC mountain bike racer, then the major concerns of your setup are weight and time/speed. Having said that, the best option for you is a single use CO2 system. What comes to mind is Lezyne’s Trigger Drive, with its dedicated Presta valve head, or the Twin Kit, complete with tire levers and a patch kit. Should you get a flat, you’ll be able to fix it quickly with a CO2 system (providing your tube changing skills are up to snuff). Should worse come to worse and you get two or more flats, you’ll be out of the running for the race no matter how you slice it and having more CO2 cartridges or a hand pump won’t really help you.


Are double centuries, gravel grinders, or everyday mountain bike rides your jam? Because weight or speed are not THE major concern of your ride, you should be rolling with a hand pump. Most hand pumps these days just bolt directly to your frame via water bottle bosses, tuck away nicely, and offer INFINITY amounts of air in the somewhat likely instance that you get 2-3 flats on one of these single, long rides.

The Pressure Drive pumps offer enough volume to accommodate a slightly larger (up to 35c) tire, are still easy to inflate to high pressures, and still come in a small, durable, all aluminum package. If you’re only running Presta valves and skinny tires, the best-selling Blackburn Airstik SL is incredibly small, sleek, and uber functional. However, if you’re needing a pump that’ll work on High Volume (read “large” or “mountain bike”) tires, then you should look at either Birzman’s Apogee MTB Mini or Lezyne’s Alloy Drive M pump.


However, if you’re the type of person that has a 14-week emergency stash of water and canned goods (as in, you like to be prepared for anything and everything because inevitably, it WILL happen), then the proper answer to this question of “Should I use a CO2 or a hand pump?” is BOTH. Why? Carrying both a CO2 system AND a hand pump allows you to beat almost any situation that may arise. This holds especially true since a complete CO2 system (like Lezyne’s Twin Speed Drive) can weigh as little as 69 grams and fit nearly anywhere. The weight and space factor seem to beg the question of “Why not carry a CO2?!”

The caveat in running JUST a CO2 is that, unlike a hand pump, it doesn’t last forever, while a hand pump will deliver you infinite amounts of air, but without the convenience of speed. There is also one more noteworthy option; Lezyne’s M-Caddy Sport Kit, which is very well-priced,and is relatively all-inclusive for tire repair. It comes stocked with a pump, multi-tool, patch kit, tire levers, and M-Caddy bag to stuff it all into.

So, in summary, one of the best things you can do is NOT forget tubes or patch kits, because without those, a pump or CO2 will be absolutely useless.
