Good points. Nearly all of my valves have removeable cores though, since two of the three bikes, the most commonly ridden ones, are tubeless. It makes me realize that another factor may be frequency of use; I scarcely use any of mine, whereas it may be a regular maintenance tool for some.

As for technique and “best practice,” there’s also a pressure release button at the end of the Lezyne ABS hose; pushing it before unthreading the hose may allow users to hear air escaping if the core is unthreading, and to get it retightened before all pressure is lost. Pulling a core is not the end of the world because it can just be screwed back in, but having to reinflate from zero is super frustrating!

same problem

Even the Topeak RaceRocket HP is better than the Silca Tattico! But the Lezyne Road Drive large is better than the Topeak, I have both, and from memory the Topeak takes about 50 strokes more to get to 90 psi than the Lezyne, and the effort is higher. From test results I saw the Silca takes about 150 strokes more than the Lezyne, and takes significantly more effort to get to just 70 psi, some complained they couldn't get to 80 psi with the Silca.

I won't use a insignificant pump on the road that can't get the pressure up to riding psi just so I can get home, I want the tire pressure to be what I would put in my tires at home with my floor pump so I can continue the ride.

While the Silca is a very well built pump and should last a very long time, but so will the Lezyne and the Topeak, my Lezyne is 10 years old, and my Topeak is about 13 years old, both are fine and no reason they can't last at least another 10 years; the Silca is the heaviest mini pump on the market, and the Lezyne is $20 less than the Silca non bluetooth version which they no longer make due to problems, the Topeak is only $5 less than the Lezyne.

Lezyne sells a ABS pen gauge replacement hose for the large Road Drive for just $26 if you want a gauge.

Sorry, no experience with the Silca.

I've used the Lenzyne Road Drive, on our tandem (32 mm tires pumped to 110 psi). I actually like the screw-on head, it feels very secure and with the little flexible tube you can really push on the pump without worrying about damaging the valve. I didn't have any problem with unscrewing the valve core, but I'll keep an eye on that in the future. It took a while to pump our tire up, and yes, the pump did get warm (not a problem when you have padded cycling gloves). As with any pump, the last strokes were hard, but I was able to get the tire up to pressure pretty quickly and easily. I like the Lenzyne about as well as my Topeak Roadmorph, which is larger and takes fewer strokes to fill a tire.

I didn't like the Topeak Road Morph, not because it didn't work good, because it did, but it's not a mini pump, it's a half size frame pump, it's very ugly and ungainly, and the mounting system sucks. If you want a better frame pump go to a full size Zefal HPX4 frame pump instead, it actually works better than the Topeak Road Morph, and looks nicer, ask me how I know. If you prefer Topeak brand, they do make a full size frame pump that is quite nice called the Master Blaster (not sure if this is being sold anymore though), but stroke to PSI is close to the same as the Zefal, just depends on which one you like the looks of better. Silca also makes a great frame pump, but it's ridiculously expensive, stroke to PSI is also close to the same, sure it could last a lifetime, but it cost $175, the other pumps I mentioned cost under $50, and those will easily last 30 years, see the price per year cost here yet?
