Is anyone familiar with the SKS Airgun or any co2-powered tire inflator? I'm contemplating on getting one because the present pump that I have is no good in properly inflating my tires to my desired psi. Your opinions and recommendations will help a lot.
Thanks in advance everyone.

I do.. just carry them for emergency. I still carry my portable pump everytime use my camelback. . When use them make sure to mounted right cause you lost air fast. Advantage: -fast to implate tires. - light to carry (specially on races) Cons: -expensive

Jr,
Thanks for the feedback.
I've also asked a couple of LBS and they concur that they do the job as described and they don't come cheap. Funny thing is, they're not sure if the co2 cartridge is refillable.
Just curious, is it?
I use UST tires and the present pump I use is not good enough to inflate the tires to my desired psi. I've read some articles recommending co2-powered inflators for tubeless tires and they get the job done. Is there any tire inflators you know that , if not in par with, at least come close to co2's?
Thanks again?

Funny thing is, they're not sure if the co2 cartridge is refillable. I don't have any experience with the CO2 inflators for bikes, but I have some experience with CO2 cartridges for airguns. Most of the CO2 cartridges out there are not user-refillable. You just send them back to where you got them (minsan, may deposit pa). I do, however, have a refillable CO2 cartridge that has an input which you can connect to a 5lb CO2 tank for recharging. I don't remember if these things are common, or what the max capacity of it is -- might not be enough for a tire.

May nakita ako ang gamit yung sa air gun na malaki, may adaptor ba na nabibili niyan?

The cartridge is disposable.. is more expensive to refill them.
gavinchie - IF you get flat dont EVER dismount the tires from the rim. As soon as you dismount or dislodge from the rim grove you are going to have a hard time putting it back specially if you are on the trail. This happen to me once and I tell you I walked 2.5 miles to my car. A regular pump will not work.
Tubeless tires are not easy to puncture. Just lost air (2 -3 psi) within 24 hours. I used regular floor pump at home when I dislodge my tires. Make sure to apply soapy water around the side of the tire when you mount them.
Tubless fix secret when you are at the trail:
super glue - Solution -this a quick solution to seal the puncture when you are at the trail. Just find the puncture area, release the air (DONT dismount tire from the rim grove) ,apply super glue then use regular mini pump.
C02 - use this as an emergency when the tire dislogde from the rim grove. Solution -when the tire out from the rim grove, apply moderate water on the tire(around the were mounted to the rim grove) then use then CO2.
Spare inner tube -this is the easiest solution. Solution - remove the tires and put the innertube in. Remember tubeless rim will accept inner tube. Just remember when you remove the valve dont lost it cause you need them when you want to be tubeless again.

Some used improvised adapter nakita ko sa Quiapo, ibang klase talaga pinoy, nagawa nilang air supplier yung CO2 cartridge. Pwede din sa car.

is C02 bad for the environment?
just read it on an article (issues with paintball guns)

No. Plants need it for photosynthesis. Woofs, guess you forgot our present environmental phenomenon right now? greenhouse effect? carbon dioxide absorbs reflected infrared radiation. This absorbed energy are beneficial to mankind by maintaining the livable ambient temperature. But with recent boom in the industries and rapid loss of the rainforest, this balance was affected. I dont have to continue coz it will be a long tale, bottom line is.... El Nino Phenomenon 1st lesson of the day...is science ;D I guess everyone heard of the Kyoto Protocol, if not here's the link: Kyoto Protocol

Woofs, guess you forgot our present environmental phenomenon right now? greenhouse effect? carbon dioxide absorbs reflected infrared radiation. The CO2 from airgun hobbyists is nowhere near that emitted by the burning of fossil fuels. In fact, I would say it's insignificant. I'm no chemist but I would suspect that CO2 for pressurized or industrial applications is generated chemically w/o the hydrocarbons associated with burning of fossil fuels. Heck, I even generate CO2 via a sugar/yeast reaction to fertilize my aquatic plants. No need to lecture me on that. I'm a science nerd myself.

I know its negligible its just a response to your answer on Max question. CO2 the Airgun hobbyist are using not exactly pure CO2 its just a compressed air, I myself have one this. Well I guess I can speak well for this since I'm a chemical engr and currently in the industry which is involved in this field. Ironic part is we're the one making this facilities who extracts, refines fossil fuels (Sorry guys, you need fuels too right?) Hey I like the sound of your sugar-yeast reaction....hmm sounds like your making your own ethyl alcohol huh since thats my thesis also way back in college. Oppss this is completely Off the topic...sorry

Yeah, I figured it wasn't very pure. Haha, your thesis was on lambanog? ;D Yeah, alcohol would be the end product of the fermentation (sugar water + active dry yeast), but I have no intention of drinking it. I did it to generate CO2 for injection into my aquarium. It really does help the plants grow faster. Combined with high levels of flourescent light in the correct spectra, I had measured plant growth rates of up to 1.5 inches a day.

Ngek bat mo alam!?? done research on aseptic collection of the materials to increase the alcohol concentration hehehe single stage distillation lang ako...pero mataas na rin concentration. Oh? interesting project you got there... thinking of doing some project also relating to agronomy but still dont have time to do so. By the way, are you using molasses/unrefined sugar, intend to use a different strain of yeast before but those critter arent available locally Will PM you more later, we're muddling the thread already ;D

CO2 is a must on every ride especially if you have tubeless tires. it's the only way to inflate those tires if ever they get flat. handheld pumps is useless in this situation.

ngek! that doesn't sound promising for UST systems then. Yep true staind, we been thru this topic before with jr, if I can find the thread I'll post it here. One alternative to trail repair your tubeless if the sealant can handle it is using a super glue, you'll less likely to sit the bead by handpump alone or even the CO2 inflator if you unmount the tires. Some tires are too stubborn to sit itself and seal without the help of soap & water. heres the link Tires

i was forced to get a Zefal Air Flash II co2 kit, b/c none of my hand pumps would fit onto my frame. A 12g extra tank costed me PhP51, and the pump itself PhP750...both from Toby's Galleria.
seems simple enough...but wonder if those tanks once installed in the pump, will leak even if the regular and handle are closed all the time...
... would like to store the main tank in the handle but afraid it will leak over time even if not used. suspect kasi that once you stick the tank in and close the handle, the tip of the tank is automatically punctured...tama ba?

yes gulli...overtime it'll be emptied out. once i opened one, i'll make sure i use every bit of it. I used to have Zefal like yours, but it blew up on me. thought it was completely empty...i decided to start unscrewing out the canister with a 16g inside without checking it. it exploded right off my hand into bits and pieces. it blewn out the rubber O-ring including the needle inside. just a heads-up. www.pbase.com/kiddfoes/inboxthat's all was left.

WHOA!!! must have freaked you out brad! and it doesn't even give you a warning on the package...sheesh! ok, so if i want to keep this explosive device in my kit, i will need to: 1) load the CO2 cartridge only when actually needed; and 2) make sure the cartridge is completely empty before removing it. tama ba brad? and this exploding thing, is this something that the zefal co2 pumps are prone to? what about the SKS ones...would you know? thanks!

your absolutely right Gul! Zefal has nothing to do with it....i did the dumbest thing that a biker would sometimes do. my bad. it scared me a whole lot jr...i can feel some of the CO2 powder went into my face.
i don't know about SKS CO2 pumps yet, but i do know SKS floor pump. i have a Genuine Innovations "Ultraflate PRO" now and so far i find it more handy and convenient. No more adaptors needed like the Zefal if you'll gonna use threaded CO2s.
