This horse has probably already been beaten....please give this rook a break....

Pros & Cons of each...

The last frame pump I bought, (CrankBrothers) was/is a piece of crap and left me frustrated at the side of the road...

Please advise...

Thanks.
CO2 + miniNessism

Keep the mini but add a CO2 shooter. Seat the tire with the pump and bring up to 10 psi or so. Next, shoot the tire full with a 12 gr. CO2 cartridge. Fast and simple. 12 gram cartridges are used for air guns so you can buy a bulk pack of cartridges at Wall Mart for cheap.

Bulk cartridges - are they threaded or nonthreaded?Eug

I'm talking the wall-mart ones. I'm wondering what head for them to get.

Can you get 25 g bulk ones?

The cheapo air gun cartridges are unthreaded. From my experience, a 12 gram shot will fill a 23C tire to about 90 psi or so. If you fill the tire to about 10 psi or so before using the CO2, you should have 100 psi in the tire which should be enough for most people.

Probably a minority view, but I'd keep the pumpretro

I'm a Clyde, and I use mostly 32-35 tires. Even a big cartridge won't get those up to pressure (the standard 12gm only hits 70-75). Saves a little work to do what you can with the CO, then top off with the pump, but to me it's not worth the hassle and expense of remembering to buy the things, then carrying two kinds of inflation.

I've been using C02 for several years but recently bought a Zefal HPX frame fit pump for my long-distance bike. With CO2, I carry the inflator and 3 cartridges. I weighed all that stuff and my Zefal the other day, and the weight is about the same either way. I get a little nervous on long solo rides with the CO2, in the event of multiple flats. On a group ride, I don't worry about it because someone else is bound to have a spare cartridge if I run out. CO2 is definitely quicker and less work than a frame pump, but a Zefal pump will pump to needed pressure with no trouble, will last for years, and I never have to worry about running out of cartridges. With a Zefal pump, if some Team Cinzano jerks give you any trouble, you can stick it in their spokes or beat them over the head.

yep...I totally agree...just replaced my old HPx after 15 years of faithful service w/ a new one. Tried a mini pump for a short while, but found that it would not pump enough air to find a puncture before the tube deflated...most annoying. It is indeed a good thing to have a weapon of some sort for dogs, etc...a frame pump was also used this way to great effect in the novel "The Yellow Jersey"
I recommend a frame pump without reservation.ctheronj

I have a Zefal HPX frame pump. I hardly know it's there; it just sits under my top tube all the time (until I need it). I can't remember any time that it has run out of "air", either. One time a dog bit at my shoes (no penetration) and I waved the pump at its head (no contact). The dog left.

If you check out the general forum, there's a rant about cycling being so expensive. Zefal frame pumps are cheap, and they last -- I guarantee you that if you buy one, it will last longer than the novelty of using CO2. And unless you're moving to Planet Spaceball, at least the air that you're putting into your tires will always be free.

I used to use CO2 but got a bit bored of having to deflate-reinflate when I got home, plus fear of multiple flats (regularly ride on my own).

I've now got a Road Morph (made by TopPeak or someone?) - a fraction heavier than a Zefal but similar size (whats a few grams when you've got a full waterbottle?) but its got a connecting tube to the valve and a little leg that folds out, turning it into a small track pump. Pumps upto 130psi in seconds - none of this "get you home" stuff. For me, any small additional weight (as I said, we're talking grams) is more than offset by always being able to ride with rock-hard tyres, which lets face it, is a far more noticable factor.

Second the Road Morphwilsonc

I've got the Road Morph as well, and it is simply the best frame pump out there in my opinion. With the hose and fold out leg, it is 95% as good as my floor pump, and that is saying a lot for a frame pump. It really can pump up to 120 or more without much trouble.
