Yes. I carry a couple co2 and all I use. Less than one will get you to 50 lbs easy. If small enough a hand pump not a bad idea but I don't carry one on trail. Spare tube and kit with the co2 In my camelback.
I carry both. I know its cumbersome but i dont trust just having the co2. The only time I used it was on a long ride with a buddy where we had traveled a bit and didn't want to waste much time on the side of the trail. We both got flats and having those co2's to blow them right up was way better then wasting time and energy on pumping up 29 2.35 tires.
I carry both as well. I don't trust only having co2 because if you get multiple flats in a ride and don't have enough spare cartridges you're walking out. I personally wouldn't consider co2 if I hadn't gotten my inflator for free. I carry a Lezyne hand pump in my pack...the weight is minimal.
My enclosed one will take either type of cartridge, threaded or unthreaded.
The make is UNICH
You can store the cartridge inside the unit, to use you just unscrew the case, turn the cartridge round, and screw the case back on.
This pierces the cartridge and it has a button to deliver air on demand.
The adaptor screws on to Presta or Schrader valves without any changing of parts, you just screw it on to whatever valve you have on the bike.
I have been wondering which to get. A hand pump would be tough to get 30 pounds of air into a tire. Some of the pumps are kinda cheesy looking and I wonder about the longevity of them. I would hate to rely on one and have it fold in half before I get the tire aired up. The CO2 is probably the best option with a hand pump as a backup.
I think CO2 could have advantages for tubeless, and of course convenience, but I'd never be caught with a pump on purpose. I personally just cut out the middle-man and just carry a mini-pump. It really doesn't take that long to fill up a tire, it's always there, never consumes money or require you to stock and carry anything else. There are definitely a lot of sucky ones out there; I once actually smashed one to pieces on the side of the trail, it sucked so bad. But, gotta say I've had a great luck with this one.
It kinda converts into a mini floor pump (a little pedal levers out of the bottom to put your foot on, the handle rotates 90, and it's got a short hose so you work it just like a stand up floor pump and don't have to get all awkward about it. I've pumped up easily 100 tires with the one I have now with no maintenance beyond a very irregular drop of oil. I'd definitely buy it again.
Nothing wrong with using co2s on the trail. Tar and feather ppl that look down on ppl for wanting to finish their ride not spend 15mins pumping a tire
I dont carry a pump usually. I have one that stays on my commuter but my mtb I carry my chuck with 2 16g co2s.
And my point in doing so was proven. Try seating a tubeless tire back on the rim on one side that's completely off with a mini pump. Used my co2 first time last weekend and saved my ride. Able to finish my entire ride no issues.
Just don't be that douchebag that leaves the empty canisters trailside. Take them out with you.
