[Closed] Track / Floor pumps, do you care about accuracy of the gauge ?

Never met a track pump with a good gauge.
If you want to know the actual pressure, get a separate device or two to check it.

If you're only going to use one device though, you're more interested in repeatability than accuracy.

I don't care about accuracy, just repeatability. And tbh on the normal bikes I don't care too much about that, it's really just on the fatbike where it's critical for me

So I have 2 of the same topeak pump and 2 of the same digital gauges and they all read in the same ballpark, no 2 are exactly the same but they do the job

only to the nearest bar.

Accuracy, no. Consistency, yes.
I just want to know that 30psi (or whatever it is) is the same every time. It might be 40 or 20 in the real world, but that’s not important as I only use that 1 pump anyway.

I been aware that pressure gauges on pumps aren't that accurate for a while, but they give you a reproduceable scale for each time you inflate tyres with that same pump.

My good track pump is ~20 years old and cost ~£30 back then, I have that brand new Lidl £7 unused one in work locker.

I kept thinking about buying something like https://www.merlincycles.com/bbb-bmp-90-pressure-gauge-64692.html or the https://www.amazon.co.uk/Schwalbe-Airmax-Digital-Pressure-Valves/dp/B0025TYV7M , especially after buying the Wazoo fatbike, but it's another bike thing of low priority on my low disposable income for "toys I'd like to have."

Have to admit though, I'd be mildly curious to how my old track pump does at ~28PSI for Jumbo Jim rear through to ~80PSI for 28mm GP4000S IIs on my bikes.

Fair enough, maybe i was expecting too much.

I'll just re-check with digital gauge.

my cheapo joe blow even has a little rotating bezel that I can point to where I want on the dial. Verify with digital gauge.
Assume it is uniformly shit and doesn't vary over time.

Does it even matter, pump it up to what pressure you think you want. Go riding. If its too hard let a bit out, to soft.....

I looked into this a while ago - Pressure gauges are accurate around the middle of their range so that Park is probably pretty good around 80-100psi. Most track pumps are intended for road tyres so they're good for about 80-120

Even a good gauge at those pressures would be pretty hopeless in the 15-30 range you're using for mtb tyres (and there's little scale to make small adjustments).

I stuck a £6 60psi Wrekin gauge from eBay on the RennKompressor that does my mtb tyres. More accurate, cheaper, and less faff than a separate gauge BUT of course now no use for road bikes or seating tubeless so I've got other track pumps.

I have a fabric 0-30psi gauge which you can connect in line with a floor pump - best of both worlds!

I have the same. I also connect it between my compressor and or the fire extinguisher inflator.

No, and

Or do you use something like a digital gauge instead afterwards ?

No

Most useful dear, you're a bundle of joy and information to this place. I don't know how we cope when you're not here

You asked a question, I answered it. Not everybody overthinks absolutely everything. Some of us just enjoy pedalling 🙂

As above, consistency.

Don't care what the PSI says, just that the tyre will feel about what I'm used to each time.

Issue I have though is multiple track pumps. In the house and in the car. They may not be the same. I need to calibrate really, ie work out what the reading is for the same pressure I like on each and mark that.

As above, I don't really care that my tyres are an ISO-calibrated 45psi, I care that they're about the same as they were when they were last on my bike / gripping well...

to the nearest bar.

Great advice. Are you buying Klunk?

Weeksy, you often ask questions and then ignore or berate the advice / answers given. If you know so much why ask? I'd trust Simon's experience long before I listened to your nonsense.
