The differences we experience with template and altitude probably negate its practical utility, but I’m still intrigued. I guess a more reliable pump with a precise gauge would also work.

Won't a digital pump be more accurate?

Those seem interesting, but if you are deflating tires, won't you already have a gauge for when you air back up?

Limited to 30psi, so only a narrow range for bikes..

Not sure why you'd need 4, for when you lose one? :D

This is yet another problem that I have never noticed. The terrain I ride my bike on had orders of magnitude more variability that disguises the minuscule effects that atmospheric conditions or hamfisting a pump will ever have. Perhaps I need to ride more NIST traceable IMBA standard trails.

What I was thinking is not to inflate, per se, but regulate deflation accurately out on the trail, as they are tiny.
Sounds like this solution is not exactly practicable for bike stuff, yet.
However, I am always keen to see if technology and products from other industries could be used, or could be the basis of an idea for something that could improve cycling.
It’s really just curiosity, I like imagining how things could fit together that don’t seem obvious.
Most inventors and tinkerers try hundreds of different things (or thousands) before stumbling onto something truly useful.
The key is to look past the naysayers, I guess.
Kind of a hobby.

Tirewiz?

There was a video or photo article from Taiwan, perhaps from earlier this year, where someone had a similar Tire pressure thing; no battery, simple, small and even more integrated than that thing above.

How often do people take pressure out on the trail though? Maybe a squirt or two here and there, but most people aren't too far off when they start?

Well, I usually overinflate a little before leaving the house, as most of our rides start with a 1500-2500ft. climb, generally up the whole way, (and on pavement for Pass laps, etc). and then deflate a bit for the descent. And honestly, I almost always let too much air out, and have to reinflate. It would be nice to just know how much to deflate to.

This is missing the point: I would love to just have a valve cap that regulated how much I let out, without having to pull out any tools or such while others are waiting. Just press on it like a Reserve valve, and I would be ready to roll.
But yes, I way overthink everything.
That said, I need a new gauge, and that one looks the bees knees.

Check their latest model it has 0.1psi resolution instead of 1psi

Jesus, on purpose? You weren't violently coerced or anything? You must fucking hate money. I was trolling tbh.

A $40 floor pump and a $20 pressure gauge will give you more accurate pressure readings and cost less than 25% of what that thing costs. A digital shock pump will have that all in one place.

That pump is an an affront to humanity and a monument to man's hubris.

But you'd still feel like a poor person.

People spend $850 making a thousand dollar fork work properly.

I just grab mine and squish it with my fingers to see if it's close to where I like .

Always fill to a certain number (gauge I'm sure isn't exact but close) then deflate a blip here or there till it feels about right ..usually comes in almost the same with in 1 psi Everytime...

So squeeze the charmin, it works...

And yes I like my boobs, I mean tires a certain firmness based on how it's about to get ridden

That has been my MO for decades. But now with 11 bikes in the stable, and all of the combinations of tire size, sidewall stiffness/casings, inserts, etc, my internal pressure gauge is outta whack…

Shit 11, that's Impressive..(that deserves a tolerance award lol)
I have 3 with a 4th on the way and it's already too much non conformity..

I dial for feel and write it down , print it on a decal for top tube once a bike is dialed ..2 baselines, rocky course tech and jump line drops freeride set up, psi tires..
I don't have to think just count and click now. Tires I put a dialed pressure but it varies and I usually do it by how it handles first section.. I'll stop squeeze and take out till it gets rid of my issue with it...if I know there's g-outs and some hard berms I'll keep it a bit firmer and deal with chatter and drifts...

Great now I want one for no real reason.

Also - a push on gauge that does 280psi? Bahaha I want to see that.

Health and safety at work has rules twice as rigorous as industry standards for robots but people regularly get absolutely shit whipped disconnecting 3" quick disconnect pneumatic lines after forgetting to bleed off the pressure.

3"?? like 75mm?? holy hell.

I worked in a factory where some knocked broke a air hose off a machine and the hose and broken nozzle part whipped around like a cut snake. That was 25mm hose @ 8 bar and there were dents in the steel walls and smashed stuff everywhere by the time we valved it off.

I've worked with a lot of scary machines, the 3" pneumatic lines and 400 Amp extension cords are the things that scare me the most
