Although the flexible hose is not very long, I think it's still enough to reduce the risk of yanking on the Presta valve while pumping - and it stores inside the pump.

I considered one of the Lezyne Micro Floor Drive pumps, and it looks like a nice design, but I think it might be just a little bit too bulky for how I want to carry it in my frame bag.

I'm going to try the large version of the Road Drive as a compromise.

I have a Topeak Road Morph G with a little "foot" that makes it work more like a floor pump than a frame pump. It has a gauge too, but I don't know how accurate it is. It works just fine. I also have a Cannondale brand pump I bought for a second bike (got tired of moving the clamp that goes under a water bottle mount between bikes), but I haven't had to use that one yet.

I wouldn't know how to use CO2 cartridge but it seems wasteful to keep buying disposable canisters instead of buying a tool that should last for years. I assume they aren't refillable or people wouldn't leave them on the side of the road.

Regarding the risk of snapping the stem off, I was taught to hold the wheel AND pump head while pumping. Once I learned that, I stopped shearing off stems. Is there more to it that I don't know about?

I have an old TopPeak pump that has two small diameter pump chambers side by side. The chuck has a high pressure and a high volume setting. Flip the chuck one way and it airs the tire up pretty fast, flip it the other way and finish up with the higher pressure. Has a built in gauge I don't pay attention to because it probably is very inaccurate. Does presta or schraeder valves. Never used a CO2 inflator and probably never would as long as my current set up still works.

As an aside I hate things attached to my bikes. Lights and a cyclo-computer is about all I will attach...I don't count bottle cages !! I wear a Camelbak Lobo with the bladder removed. I put the pump inside where the bladder goes (there is a mesh pocket for it but I am afraid it may fall out.)as well as any bigger gear that I may need to fit. All my tools/tube etc. go in the small upper pouch, wallet and keys in the roomier lower pouch. Bike stays with the clean lines : )

Yeah, it's called a hose. Having a hose-equipped pump is way more efficient, allowing the user to more comfortably work, without having to manage the wheel. Much easier to wail on for those last few PSI.

If the connection to the valve is rigidly mounted to the pump, then yes, I would try to hold things so as to avoid trauma to the valve stem. Been there, done that - but my current pump has a flexible hose leading to that connection.

That's part of the reason that I'm still mulling over the Lezyne Micro Floor Drive - longer hose, on a swivel.

Plus, both Schrader and Presta, and the ability to hold the bottom of the pump against the ground while wailing on those last few psi.

Lol, thanks again for the great input everyone. Right now for my riding type, I think I'll stick to a 20g CO2 cartridge (maybe 2) and inflator in my saddle bag and probably pickup the Lezyne Pocket Drive pump to carry under my cage as well. Anyone know the difference with the Pro version outside of more color options and maybe better build quality? I notice in the description it also has a valve core remover on the hose. Does the non pro version have this also? I'm looking at a $15 difference and don't mind spending it if it justifies it.

Reading the descriptions, the regular one is constructed from CNC while the pro is "fully" constructed from CNC. That and the 19g weight difference tells me there's more metal parts on the pro. Not sure if any of those parts are that important, but I suppose the valve core tool is nice considering a previous post saying it was easy to accidentally unscrew the core when using the pump.

Yeah after hearing about all the folks having issues accidentally loosening their valve cores, I was thinking the same but would I be better off just carrying a separate, better valve core tool. Is the one that comes with it good enough? I'm running tubes btw so I won't need that tool for anything else most likely unless I add some sealant to my tubes for extra protection?

If you ever buy a packet of extra valve cores (e.g., on Amazon), it will come with a tiny plastic thingy for dealing with valve cores. That is the best tool for carrying on the bike, as it weighs almost nothing and takes almost no space.

Some multi-tools have them, too - they often do double-duty as a spoke wrench.

The Silca Tattico that I recommended doesn't thread onto the valve, so unscrewing the core is a non-issue.

I don't know. I have only ever used the plastic valve core tool that came with Slime way back in the 90's, and I can't imagine using it so frequently that it gets worn beyond use.

It sounds like the addition of the valve core tool shouldn't be a dealbreaker between the Pocket Drive and Pocket Drive Pro as I can grab a cheap, small solution to stash in my saddle bag.

Do you need Schrader valve capability? If Presta-only is sufficient, then you might also consider the Road Drive.

That's available in three sizes, all of which are longer than the Pocket Drive. As a matter of personal preference, if I could comfortably carry a longer pump - the biggest Road Drive is just over 11" - I would. Full disclosure: a pump is my only inflation option right now, not a backup!

If it's going in a pocket or saddle bag, then sure, small pump is better than no pump.

I always either wrapped a couple of fingers around the rim while I was pumping or, if you were reinflating after a flat, pump up the tire before refitting the wheel. Allow the wheel to swing free while pumping. The weight of the wheel alone isn’t enough to damage the valve stem, it’s the hauling on it while pumping that does it

One video I saw suggested just using Schrader adapters on the presta value to avoid the valve core issue.

I do the same ... between my quads, of course.

Carry a mini pump and CO2 for my tubeless setups. This is what I collected at mile 12 after climbing 950’ this morning.




Lost 3 PSI and rolled home 3 miles at 77 PSI with the nail. Plugged it tonight and it is holding fine, will see how it does in a couple of days when we get out of the 100*s. In the old days it would have been tire removal, new tube or patch. I just looked at the nail and rode on figuring if it got worse, I could plug it and reinflate with CO2.

Well I took the plunge on a Pocket Drive and also a Pocket Drive Pro since the deal was too good:
https://www.ebay.com/itm/144067471646

https://www.ebay.com/itm/133797952231


Now I can have one on each bike. I don't want anything too big but still usable in a pinch and well made and they seem to fit the bill.

Thanks again for the input everyone.

Edit: I don't know why both of my links are coming up with the standard Pocket Drive but if you search the sellers other items he has the Pro available too for $31 shipped, non Pro $20 shipped.

here's another vote for both

I acquired several pumps over the years but the one I carry has proven to be dependable, effective & easy to use Blackburn AirStik. that link goes to the current "anyvalve" model. I have 3 bikes so I mounted the same mount on all 3. I just have to the remember to move it to the bike I'm taking out





I have a very effective, dependable & easy to use CO2 inflator Genuine Innovations G2673 AirChuck. it's just a tiny little thing so I keep it in a small plastic zip bag w/ some patches


when I have a road or trailside flat repair I use the CO2 inflator. when riding in very cold weather I keep extra cartridges in a pocket because they don't really work well when frozen

having a hand pump is good for when I air down my MTB tires for a soft section but then want a cpl more lbs when I'm back on harder dirt. no sense to using a CO2 cartridge for just that

fwiw - I covert all wheels on all family bikes to Schrader valves. easy peasy, durable & flexible when hand pumping. also easy to inflate at a gas station if necessary
