There seems to be a bit of a trend where I live in Rochdale where cyclists just toss their empty CO2 canisters to the roadside once used. I cannot seem to go on a ride anymore without passing at least one canister discarded in the gutter. If you can carry the canister on a ride with you, then you can carry an empty canister back home with you!

[@eddymintball1950]

These aren’t CO2 canisters discarded by cyclists, they are nitrous oxide used as a kind of feel good gas used by the yoof of today

you can buy a pump that fits in your hand, charges by USB, and puts in up to 100psi. even less effort than a bloody canister. they're on aliexpress and cost about $40USD. not sure what benefit a hand pump or co2 canister could possibly have over that.

[@justjordan8018]

Pump all the way, even mounted on the frame, in shiny proud Red. I ain't afraid of no punchures, had one 3 days ago, cost me only 30 seconds to inflate the tire. Now removing and putting the tire back on the rim ... that was 30 minutes job.

[@mattwurst3755]

A little bag on your toptube is just perfect!

[@mantrajack3549]

I also used to carry around a Presta/Schrader converter for using the gas station air compressors if I need that extra amount of air in my tire after an inner tube emergency :)

[@kermatog]

never considered that... chucking that in my kit right now

[@josephkozachek848]

For the pump: you can pump up the flat tube to see where the hole in the tube is...so that you can check the corresponding spot on the tire for something poking through the tire ... avoiding a second flat more effectively. if you only have 2 cannisters and miss a thorn etc...or get two flats from the same debris and dont detect that thorn/glass/wire shard etc....you are stuck. Pro the cannisters: higher pressures than you can reasonably get with a tiny pump in a realistic time frame, smaller, more compact.... But... mostly Im running tubeless now so Ive gone to the cannisters and a spare tube (only one) but also a plug kit as back up and knock on wood...havent had a problem

[@rossfripp4503]

On any half decent CO2 valve you can adjust the air flow and stop "mid-flow"....so there's no reason you couldn't do what you've described above with a CO2 canister :)

[@KandiKlover]

I put sealant in my inner tubes so never an issue for me.

[@alexanderSydneyOz]

Good point about finding the thing which caused the puncture. I did years ago walk a bike with a flat tyre, and the bit of glass stick in the tyre ended up creating hundreds of punctures. I commute only, have a hack bike, and patch tubes. The pump is much better for that process. That said, I have been using puncture resistant tyres for about 4 years, and the only flat I've had in > 10,000km of glass shard covered city streets, occurred on excessively worn tyres. I do also give the inside of the tyre a wipe around with the (gloved) hand to ensure nothing remains sticking through.

I've got both. The CO2 inflator is the first line option; and the mini-pump is there (on a bracket mounted behind a water bottle cage) for days when things go all pear shaped. Does my mini-pump mounted on my frame make may bike and me look less racy? Maybe, but no one looks racy sitting by the roadside with a flat tire they can't inflate.

[@glenspringle7337]

Robin Seibel I carry both. The mini pump is for pre-inflating the tube, and finding a leak to patch. Once the tube and tire are on the wheel, CO2 to get it to proper riding pressure. I spent too many times trying to get pressure to 80-90psi with a hand pump...it takes minutes! To get high pressure, they have low volume per pump so it takes FOREVER to get a road wheel up to pressure... CO2 takes about half a second.

Great timing for this video - just suffered a puncture yesterday! I carry a Lezyne Road Drive mini pump, and it performed flawlessly. It's absolutely advantageous in allowing you to put a few PSI into the tube before placing onto the rim, before completing the job once you make sure the tube is totally within the tire and allowing the beads to seat properly.

[@TheMonsterPool]

There is another con of the co2 pump you forgot. The co2 molecules are so small that they slowly permeate through the inner tube. So you should always replace it with regular air when you get back home.

[@aldrinclementina4297]

You'd never understand the joy of canisters until you've pumped a road tire to 120 PSI with a mini pump. Especially if, by Murphy's law, you're late and just before the top of the climb (i.e. very tired). I, personally, ride with both. Also, please do a video that shows (in real-time?) the time and effort it takes to pump a tire with a mini pump. Just as a service to show new riders what to expect. Maybe as a comparison to find the quickest/best pump?

​@@bobwho1986 I would, and have, still gone with the mini-pump. If you're in a race or want to get home as fast as possible, sure, it's not the best. But it took Si well under 2 minutes to fill his tire with the mini-pump, which is perfectly reasonable in my opinion. Also, why is OP filling a road tire up to 120PSI? Unless you are carrying a lot of weight or have something ridiculous like 19-21C tires, you should be able to get away with far lower pressures. There's also something to be said about having a nice, quality tool you can reuse over and over again, which is great if you're riding casually with friends that don't carry anything with them and they get a flat. Buy once, cry once, and such.

1:15 I have that Topeak aluminium pump. It's a total pain in the butt because of bad design. The handle is an aluminium tube that attaches to the piston shaft by just having a piece of plastic pressed into it. So, if you hold the handle and try to pump, you're pulling that cylinder off the shaft. You have to use an awkward grip so push against the end of the shaft, rather than holding the handle itself. And I've never had the patience to get more than about 45psi from it, which isn't a lot of use for 25mm road tyres.

[@davidperkins3621]

Lezyne mini-pump comes with a flexible connector so eliminates the risk of snapping the valve off the tube. Use this and CO2 and feel relatively well covered. And what about the good old frame pump?

[@kevinjfeeney77]

I use the Topeak Turbo Morph....also has the flexible connector that prevents valve damage

[@panzerveps]

A friend of mine managed to unscrew the valve after inflating the tire... That was his third puncture of the day, so he had to call a taxi to get home. Good thing I was only 20 km from home, since he'd borrowed my one and only inner tube...

[@grumpynerd]

I was going to ask the same thing. Why not even consider a frame pump? But I think I know why. Back in the day frames were made with round steel tubes of standard widths, and if you didn't have a pump braze-on you'd just use a pump designed to squeeze in between any bike's head tube and seat tube lug. In these days with custom carbon fiber construction and hydroformed aluminum, bike frame members don't have standard dimensions you can count on more or less. Still, if a frame pump fits on your frame, it's the best all-around compromise of speed, capacity and reliability. I've never damaged a tube valve with a pump, even a mini-pump, but if you have butterfingers I'd suggest one that has a screw-in hose, which completely solves that problem.

[@mistermoore5784]

I've been getting tubes exclusively with removable core and injecting Stans in them; thereby only needing a hand pump to top off to 110psi. I've had the same tube for 4 years thus far. The talc within said tube makes for an excellent aggregate!

[@dtshifter]

Same here. I still carry a full size frame pump. If I have to call my wife to come pick me up somewhere I will hear about it for months and years to come.

[@dennish9519]

I was always a fan of the CO2 then one ride I ended up having to walk several miles in my bare feet! Do you patch the tube? Do you put in a new tube? I guess I choose poorly and ended up not having enough cartridges! So Now I carry and only use a Mini Pump, A Lezyne Alloy Drive. It has a short hose so that I do not put ant stress on the valve stem. The hose also can be used on both presta and Schrader valves. Another cool thing about a minipump is that if you come upon a fellow rider who is need of help with a flat I am not worried about using up one of my CO2 cartridges.

[@mikes1976]

I carry a minipump, but haven't needed to use it in years. Went tubeless in 2016, have worn out 2 sets of tires over thousands of miles and never flatted. Picked up a tack once, but the tire re-sealed without losing enough pressure to even notice. I also carry a cellphone so I can call for a ride home, but haven't needed to do that either.

[@thacktron]

I use Joes tube sealant. This goes in the tube and if you get a puncture (say a 3-corner jack), simply pull it out of the tyre, spin your wheel and the sealant inside the tube seals the puncture right away. So simple.

[@NoxiousNoodles]

One caveat, certain screw on pumps deserve to be fired into the sun for their tendency to unscrew valve cores.

[@buckroger6456]

I have one of those type of mini pumps and hate it. Also it's a pain to unscrew it from the valve stem.

I usually carry CO2 cartridges, but they have a couple cons not mentioned: CO2 will eventually eat most inner tubes, so once home from fixing a flat, let all the CO2 air out of the fixed tire and replace with air from a hand/floor pump. Also, CO2 cartridges might not be allowed for plane travel.

[@pauljeffries5678]

I ride with both. On group rides, the CO2 gets you going quicker and has allowed me to help others more quickly as well (the less prepared in the group). Since our group usually stops for folks who flat, that is helpful. But my mini pump has a pressure gauge built into the connecting tube, which is very nice. This gives me the option of even checking pressure when I inflate with my CO2 cartridge (which is a simple device with no gauge). I echo the comments about the pump being better for finding holes in tubes if you need to do a patch (out of tubes or riding without a spare tube).

[@sdqsdq6274]

really ? even those 120 psi ones ?

[@panzerveps]

I haven't had a puncture in almost two years (on my road bike), so I only bring one inner tube and a co2 cartridge. On my mtb, I bring both a pump and two co2 cartridges, as I run a tubeless setup.

[@dcmsr5141]

I have a proper frame pump with a gauge zip locked on top tube and CO2 cartridges and 2 spare tubes in small seat bag.depending on seat bags I'm looking at i can probably put that kit in there.

[@chesteryap]

I bring both. I had a co2 inflator fail on me. used up 3 tubes and a few co2 (dropped by teammates). Thought the tubes or installation had issues. Inspected the inflator post race. the small o-ring inside the inflator was dislodged thats why co2 just leaked out instead of going in the tubes.

[@philipclay3924]

Another consideration: whether or not your tires have inner tubes or tubeless. When I went tubeless, the rapid inflation rate from CO2 helps get the tire bead properly seated on the rim. It could take a try or two if you loose a lot of pressure and the tire unseats. I tend to take a mini pump along in case I have more than 2 flats on an outing (happened once).

[@garymiddleton7115]

Highly recommend the Planet X Phart pump, works like a mini track pump and is cheap as chips, but is a bit long for a jersey pocket.

[@davidf2281]

I mean, you could at least have showed _actually using_ a CO2 cartridge and minipump.

@@mar504 It would accomplish showing us something working in practise as opposed to describing how it works in theory. If you've not yet realised that the former often imparts more useful information than the latter then I'm going to have to assume you're some sort of robot.

[@publicmichaelzmit]

Got a Specialized mini pump that doubles as a CO2 adapter - both options in one package. Really nice to have for large volumen tyres like on a mountain bike; CO2 to get it filled and follow up with a few strokes of manual pump action to adjust the pressure.

[@gspa072]

Thanks for info. I always take my hand pump. However now I will be taking my new co2 inflator too. Just to have a back up.

[@SDW90808]

FWIW, I’ve had my share of CO2 adapter failures so now I carry two since they’re so small. I also have the same silver aluminum mini pump shown in the video and it has served me well. Leaving on an extended tour in a couple of weeks so I recently bought a larger mini pump from Pro Bike Tool with both Presta and Schroeder connections and an internal gauge.

[@davidbotterill5001]

I carry one spare tube, a few patches and one CO2 canister. Had a flat the other day ; first in over 5000km. Used my spare tube and my mate’s mini pump.

[@stevek8829]

OMG, 5000 k without a flat!!

[@cheesesandwich1236]

Mini pump. Do all mini pumps have that high volume low pressure/ low volume high pressure switch ?

[@frozenbean]

Can you not recycle the canisters in the UK? In Canada, we can put them with our normal curbside recyclables (aka. 'in the Blue Bin').

[@ChrisCapoccia]

biggest negative was tubes with removable cores kept getting removed by my mini pump with a screw on tip. I had to get a push-on pump. i take both cartridge & pump, but i may have to add a patch kit because there are more times with double flats lately. too much junk in bike lanes

[@mikeshelton4466]

Same problems here. I'm thinking of taking out the valve and applying a dab of loc-tite to keep from unscrewing my cores.

[@chrisl.6158]

mini pump! Coming from several-days tour riding and MTB I like to be able to inflate my tyres more than once. So i also put a mini pump on my fairly new road bike next to the bottle cage. Yes, it is hard and time consuming to inflate a road bike tyre to high pressure, but the environmental aspect is more important to me.

[@kiowa21]

I usually take both, if I am less than an hour from home I will use my mini pump. If I am hours from home on a long ride and wish to continue I will use my co2 as its so much easier to get a higher pressure in less time. Plus on a long hot day an empty but rather cold co2 cartridge in your jersey pocket is quite nice!!!

[@johnnydoe66]

I carry both, CO2 first use and a mini pump if I have another puncture. I rarely have punctures, but I have a friend who had 5 in less than 35 miles. We ran out of tubes and I only had a couple of Park Tool Self adhesive patches. I ended up having to ride back, get the truck, and go pick him up. Now we both carry CO2 and a mini pump, plus extra patches.

[@officerockstar]

I used to carry a mini pump for the reusability but my new bike doesn’t have the clearance at the bottle cage mounts. So, for now I am carrying CO2 and hoping I don’t ever need to use them. I have a floor pump, as well as an air compressor, at home and my mini pump now lives at the office.

[@zrsgamboa]

FYI: Another con of the CO² cartridge is that it doesn't hold pressure well. I got home after using one for a puncture last Xmas and the following day the tire was deflated (not flat, just very soft), and again just a few months ago. CO² cartridges are convenient for sure, but pump up your tire properly with a track pump asa u get home (must let out all the CO²). PS, I also carry a minipump, as back up.

[@rzeckner]

I carry a Portland Design Works Ninja model that combines both a hand pump and CO2 inflator in a single package. Having both has saved my bacon more than once.

[@AlexanderLi2206]

I have minipump Lezyne HP Drive. Tested at home to pump up 25 mm tire. But I could do with it only 4,5 bar pressure, while minimum 6 bars required for 25 mm tire. If I ride 100 km it would be very difficult get back home on such low pressure...

[@michellsmorgcycle4161]

I carry both a Lezyne mini pump with hose connector, and a little CO2 inflator head and a couple of cartridge (and a mini patch kit). One thing you should have mentioned about using CO2 to re-inflate, though. It is less dense than air, and will leak out faster, so the CO2 inflated tire will go flat again in a day or two. So, whenever you've fixed a flat and reinflated with CO2, you should completely deflate the tire once you get home, and then re-inflate again with a floor pump.

[@viffer94]

I used to have a combo mini pump and CO2 inflator that also took cheapo unthreaded canisters. Worked great, cheap to run and always had a backup pump. I haven’t been able to find a replacement for it so I end up carrying one of each just in case.

[@edo999100]

Quite like the idea of a hand pump but can you actually inflate to or above 100psi?

[@AlexRaha]

Best go with both. Pump to start with then a 16g canister to finish it off once tyre and tube are seated properly.

[@BikeItUK]

Safer with a pump, if unexperienced in using the CO2 I know many that have messed inflation of the tyre up leaving them not so high and very deflated. Pump for me. All the best and great subject matter thanks again Jon

[@tecnociclista5342]

Problem with mini-pumps is that on some modern tubeless wheels sets (Reynolds, I am looking at you!) it is impossible to seat a tire properly with the pressure you can get out of them. I recently sold an otherwise pretty sweet carbon wheelset because puncturing meant I had to 'hobble' home on a tire that wasn't quite as round as it should have been. That never was a problem with the old-style non-tubeless rims...so much for progress ;)

[@lesmerritt7976]

It's not the pressure that's the problem, it's the volume of the pump when trying to inflate tubless tyres. Anyway IMO tubless tyres are a waste of time and effort on a road bike, no real benefit. Tubulars for racing, clinchers and latex tubes for everything else for me. I don't think tubless are a good idea on tyres less than 28mm.

[@tecnociclista5342]

@@lesmerritt7976 The wheels are tubeless but the tires are not, I am using tubes. And yes, it is the pressure...you need at least 8 bar or so for the beads to seat themselves properly with those rims. With the trackpump I usually pump them up to around 8 and then deflate before I go out riding...there's no way you can get 8 bars into a tire with a mini-pump (at least none I have ever used), no matter how long you pump...

[@davidslater6672]

Since going tubeless, I have moved over to CO2 to be sure the tyre seats onto the rim which would be a tall ask for a minipump

[@AlexRochette]

Thanks, Jon. What are the pumps and inflators that you demoed?

[@easterlake]

I'd been using C02 canisters for 15 years before i purchased a mini pump. First time i used it, it was 100° out and the mosquitoes sucked me dry. Couldn't give it away quick enough. Back to changing tubes in 4-5 minutes.

[@ElLenadorLA]

Both, I take two co2’s and two tubes, if I end up using the patch kit and mini pump it’s been a bad day but it has happened and it did work to get me home.

[@JaidervillaTV]

Lezyne HP drive small, Mini air pump with hose, up to 120psi, can get 80psi in 174 strokes. Size 119mm, 83gr, presta, schrader.

[@digerati808]

Both, depending on my type of ride and if I'm wearing a kit or backpack. I like the co2 pump that uses a non-threaded cartridge since they are cheaper and it has a cylinder that the cartridge goes into to protect your hand when the CO2 comes out.

[@colster3]

I fall into the ‘both’ category! I have a frame mounted pump and 2 canisters. Mind you, I only carry 2 tubes. Seriously considering singles for my next set of wheels

[@darkskyatnight]

I had read that C02 filled tubes lose pressure within a day or so and are meant to be temporary remedies. No mention of this so was what I read incorrect?

[@J_Cav84]

I have the Topeak Micro Rocket you’re actually using as an example there, and find another HUGE con to be that it does not possess the capacity to pump to a psi higher than about 45-50, which is obviously insufficient. Is it actually just my pump? Design-wise, slick stylish and pocket friendly. Usefulness however is completely lacking.

[@kevinjfeeney77]

Topeak Turbo Morph is my choice. Has a tube instead of attaching directly to the valve... I can use the ground to push against instead of using my hand (the one that's supporting the valve)....it also has a gauge.

[@darrylhuculak4996]

One issue I've experienced with using CO2 is that they don't work with fresh glue-on patches. In what seems like backwards thinking, I now take a clean tube (no patches) with me as backup. If I get a flat I install the new tube, inflate with CO2, then switch it out for the patched tube once I get home. I've had bad experiences with both mini pumps and CO2, but just find the CO2 so much quicker. The bast solution I've found to preventing flats is moving to a larger tire size. Since I switched from 23 mm to 25 mm about two years and 10000 kms ago, I have not had a single flat.
