when i carried a co2 i also carried a mini pump...now i carry only the rechargeable inflator and it works great

Here’s what I would like to know about rechargable portable inflators — It looks like many of you that use them are running the wider tires now…30-35mm (or larger) for gravel or other conditions. The PSI for those is what…around 25-60psi? But for people like me, who still ride only on paved surfaces, running tires +/- 25mm that in some case require pressure approaching 100psi…is there a rechargable portable pump that can do that?

One of my adult children bought me a small inflator for my birthday. She carefully researched to select a good one.
It works very well. I used it at home on a some bike tires needing inflation. The battery exhausts on three 700c by 28.
I still carry a couple CO2 cartridges, along with the inflator. I suffer about two ride punctures annually on tubed clinchers.

The one I use is rated to 120psi and most are rated to 100psi.

The question is: Exhausts at what pressure?

Dan

How often do you flat? If once every few months, or even less than once a week, battery charge is irrelevant. I have used them and like them much more than CO2.

If that wasn't on the same ride, it doesn't matter. Just recharge (takes about 30 minutes).

Sticking with CO2. Lighter, faster, always works and I need another damn battery to worry about like i need a hole in my foot.

Mine set for 100psi and will get three 700x28 tires to that pressure. It pooped out at about 40psi on the fourth.
Just sent everyone home after my monthly poker at my house. Sorry for the delay in replying. Slightly buzzed, too. lol

My CO2 inflator cost $10 and the cartridges are $2.

But if I rode a $10,000 bike...

You would have to make sure the inflator matched the bar tape?

Rickysee 02-22-26 07:55 AM

Yes, once they get the weight down
 
I beleive they alrerady are replacing the CO2 cartridge. I love tat they also double as a digital PSI guage. But they have to get lighter first.

Past tense? Sell it or gave up cycling?

I have had more issues with c02. unscrewing the valves or leaking if you don't use it all or screwing it on and it blasts out before it's tight enough. it always seems more of a hassle. its pain if you just need a little to find the leak in a tubeless tire. even with a sealant rated for c02. it seems to cause issues. so with a good pump and a good hand pump its been good. Last time it was raining as usual so I could not find the puncture in the tire so I ran the pump and was able to find it and plug it .c02 woud never have worked. I jsuer my phone to make reminders to check the pump. so much less hassle then the co2

"If I rode a $10,000 bike, I would buy an expensive inflator to match."

I think you'll find there is no better tense to use for this sentence.

Sorry, missed the ‘if’. My bad

I have the same but I have to carry the extension hose to avoid melting the plastic valve stem of my Pirelli TPU tubes.
Some claim a CO2 cartridge can also crack the plastic valve stem, but I did not have that problem the last time I decided to fix a flat on the road.
I suspect they are using either really cheap TPU tubes or jetting their inflator at full blast.

I have metal stemmed TPUs with zero issue. Maybe you should change eventually

Many times. Generally works as well as a compressor, at least on wider gravel tires.

It's worth less after he's ridden it?

I didn’t offer an opinion on whether it mattered, merely providing the fact of my experience. Of course, it would have helped if I’d known what model if was to provide some useful context.

I would consider it when my current stash of Pirelli (3x) and Tubolito (8x) runs low. Do you have a recommended brand and model?

Mtracer 02-23-26 10:18 PM

Concerning the OP, I'm sticking with CO2s. Mostly because I run tubeless and barely use the CO2s. Honestly I can't remember the last time. But likely 2-3 years ago (10,000+ miles). I've got nothing against the mini-inflator other than I wouldn't trust that it would still have a battery charge in it after not touching it for 2 years.

I have many battery powered devices like bike computer, lights and Di2 shifting. But those are things I interact with on every ride and it works for me to charge on a regular schedule. An inflator would stay tucked into my down-tube storage. I get into that so rarely, I wonder why I carry any "emergency" gear at all. So, I don't want to have to get into that every few months (?) to recharge an inflator that I will at most use once every year or two.

An inflator doesn't give me any advantage of CO2. If it is smaller than my 2X CO2 cartridges and valve, it doesn't matter because I already easily fit the CO2 into my storage. Is it lighter? Maybe, but not enough that it would matter to me. But I'm not going to argue that it may be the best solution for others.

I thought the same thing I hardly ever used the CO2 but in winter, I would need it when I ran out of sealant or such. but I found it was causing my sealant to not dry so the holes would weep. so I changed over and now the sealant seals like it should, even though it's rated for c02.

The company has a strange name “Offbondage”. Get the metal stemmed ones in the right length for you.
