I'll bite: what's the expired ID for? :)

[MENTION=93580]Therm[/MENTION]ioniicScott - Expired DL to Identify me if I get in an accident, which has happened. I don't carry a wallet on rides.

Good thinking, thanks. :)

I have tried minipumps, but I normally use a full size frame-fit pump. I have a Zefal Mtn pump on the Schwinn, a Blackburn on the UO-8, and Zefals on the other bikes.

Zefal HP-X: best frame pump ever, and size 3 fits my 55cm frames (Bianchi, Carlton, and this Capo) perfectly. The Capo Siegers and the Peugeot have downtube frame pump pegs and take a shorter pump.

Full size frame pump for me, either Silca with Campy metal head or Zefal HPX. Like Gugie, I have rescued a number of folks sitting by the side of the road when their CO2 cartridges misfired. Also useful for discouraging errant canines.

I could get a tire up to about 110 psi with one of those, but that seems pointless these days since all of my bikes are running 28 mm tires at a minimum and that is never going to change.

I'm not at all keen on CO2 cartridges, due to waste, low reliability, and the small contribution to global warming. Plus, what's yer hurry?

as much as I feel like a Silca frame pump is the one true and pure way to put air into tires, I feel obliged to mention that racers were carrying compressed gas for inflating spare tires a long time ago.

These cylinders of compressed gas (just air, I think) were larger than modern CO2 cartridges, and the French term is "gonfleur". A search for this term pulls up various images, such as this one from Flickr..

Gonfleur can also refer to a pump, so some confusion is possible.

I seem to recall various discussions of these in the past on bikeforums, so if someone wants to find out more, it shouldn't be too hard.

Interesting!!
BTW, those size CO2 cartridges have been around for a while. The ones that fit the old seltzer bottles from the '60s are very similar in size and shape, although they are unthreaded. Makes me wonder if some machinist wouldn't have made some inflator back in the day for the "Sparklets" cartridge.

I got one of those for my Lezyne Road Caddy bag. It's the only type that would fit, along with the CO2 cartridge, tube, lever, etc. Haven't used it yet, no idea how well it works.

Another good reason to use CO2, can't get to 120psi
Another good reason to run much lower than 120psi.
Another good way to get away from snakebite flats: run fatter tires.
:D

Different spokes for different folks, that's what I say :)

I disagree. The Zefal HPx is a good pump but it pales in comparison to the Topeak Morphs. Pushing the plunger down into the ground is far easier than trying to pump at 90° to the wheel.

That's why I carry a large selection.

I have a couple of CO2 inflators (come in handy for night riding) and one of them is like this one. Don’t like it. The spring is stiff and you have to push on the head while the liquid flashes to gas which gets really, really cold. The Genuine Innovation Ultraflate is better insulated.

This, a million times this! CO2 inflators are so wasteful and you are just so much more self sufficient when you have a pump. I have a ~4" long pump that fits in my small saddle bag. I think it's a Bontrager that I bought for $5 from the co-op. I wouldn't carry it when mountain biking since it can't push much volume but it's totally fine for all emergency situations with road tires. I might get a frame pump or a slightly bigger pump now that I've converted to 650b on my primary rider.

CO2 inflators are out of the question except for MAYBE in a race where contending for the podium, but that hasn't been a consideration for me yet. :P

After my experiment riding in Virginia heat and humidity, I have decided my solution to the pump problem is not to ride in Virginia when it's hot and humid.

Regarding waste, I doubt cyclists use more than a tiny fraction of the CO2 used by paintball and pellet guns. When I shot pellet gun silhouettes and other targets I went through a few a day. In three years of carrying CO2 inflation kits for bikes I've never used even one. And the handful of CO2 cartridges I've seen carelessly discarded along the MUP or roadside by cyclists doesn't begin to compare to the dozens or hundreds of discarded cartridges I've seen from target shooters. Although there are relatively fewer airgunners using CO2 now, as compressed air PCP pellet guns are better overall and less temperature-sensitive.

Didn't it use to be, you could get cartridges of "compressed air" that was actually R12 freon? Wonder if those were ever used as tire inflators. Talk about ecocide! :twitchy:

I use this one.

Some competition pellet guns are hand pumped, but almost always are springers in some sort of sporter class. Single stroke pneumatic rifles aren't very prevalent. PCP reigns king. Where are you seeing hand pumped competition pellet guns? Hardly any ever at any matches I shoot across my region for sure.

I bet a cold CO2 cartridge would have felt nice. :)

What about size? I never see you riding with a bag big enough, and I don't really see you putting a pump in your jersey. Would you add a frame pump in your main triangle on every ride if it easily reached full inflation?

Me? I simply don't flat much. My last flat, I saw after I got home. My last flat on the road was like two years ago.

Size isn't an issue with me. Is it with you?

;)

Sure, I'd ad a frame-fit pump if I could find one that could give me 110-120psi.

Yes. Like you, I ride with a tiny saddle bag, which is full with my CO2 patch kit and wallet. My middle jersey pocket is spoken for (phone). My right pocket during the summer/pandemic is spoken for (bandana). It's nice to have the left pocket free for whatever.

I like my inflator that uses NON-threaded cartridges because the cartridges are cheap as chips.
