does anyone have any experience with these? I've noticed the Co2 in bike stores is really expensive. With my paintball experience I feel it should be much simpler and so I found this in search of a cheaper way.. I'd be pissed it if malfunctioned.

That is the planet bike co2, works fine but only uses threaded cartridges which are more expensive than non threaded.. I personally use the Silca Co2 adapter, been using for a few years now and has worked everytime.. It also only uses threaded co2..

I went two years without a flat, but had one yesterday. First time I ever used a CO2 cartridge. It went well except for the fact that I didn't realize the cartridge was reverse-threaded. I spent a minute or two trying to twist the cartridge the wrong way...

If I lived in an area where I was getting flats more frequently I might worry more about the cost. But for a flat every year or two (my current average) I'll stick with the "expensive" threaded ones.

This is the cheapest of the planet bike kits available. You can also buy extra threaded cartridges in bulk from this same ebay vendor. I bought one and within a couple of days I had a flat. It works flawlessly. I still carry a bike pump, because I'm old school, but will probably never use it again.

Stupid question, but just to be sure before ordering: This IS a C02 regulator type? I have one without a regulator; I've used it once and have not dared to use it again.

socalrider

Yes it does, the Red knob is used to regulate how much co2 goes in..

Just get a cheap unit that accepts unthreaded cartridges....then buy a 15-pack of 12g cartridges at walmart for $8.96 and you have a nearly-lifetime supply.

I have a box of 12g unthreaded cartridges and a clunky unthreaded inflator that I stopped carrying because it's bulky. But after hearing about more than one unthreaded inflator detonating in someone's hand... I'm giving away the unthreaded carts and sticking to my threaded cartridges even though they cost around $1.25 ea and the wally world 12g's cost around 50c.

What cartridge is REVERSE threaded????

Dion Rides

Thanks! I ordered one a few mintues ago. I have a small pump (Crank Bros.) but even that thing is too big for my seat pouch or jersey pocket. I hate carrying a bunch of stuff with me when I ride, so this will be perfect. I just never carried my other one becasue it didn't have a regulator.

rodrigaj

The threaded vs unthreaded cartridge cost difference is a fact. If spending 80 cents more per cartridge bothers you get the unthreaded type.

I personally like the threaded cartridge because I don't get that many flats per season so the cost does not bother me.

I don't think they even sell unthreaded here in Italy, I haven't seen any.

Innovation Ultraflate Plus...$20, get cheap CO2 after that (used threaded or unthreaded). Works like a charm, nice trigger inflation. I carry a gauge too so I don't worry about over inflation.

clausen

Why carry a gauge? A 16g puts in 120 psi max. More than I normally ride with but nothing unsafe.

i have the one the OP posted. it works flawlessly, is light and compact. i've done at least a dozen roadside flats with it, never a problem.

khatfull

In my 700x23s I can get 140psi out of a 16g cart...verified with two different gauges and the gauge on my floor pump.

clausen

WOW never seen or heard of it getting that high before. What tires? Maybe there a little on the narrow side. Still nothing a little tap the valve to bleed some pressure off.

kayakdiver

I have this one... Nothing special but it does work like it should. Being able to use both types be it threaded or not works for me. Just open it up and let er rip.
