Cannondale Precise Floor Pump: Practically Perfect

That *looks* really clever.  I wonder how they've made the gauge work like that.

of course the real test is if it's actually accurate at all those pressures - gauge accuracy usefully falls off significantly away from the middle of their range - so most HP pumps are good at road bike pressures but misread significantly at the 15-30psi of mountain bike tyres.  20psi on both my Lezyne and Silca is closer to 30.

A link to where I could actually buy one would be great 🙂

If it's anything like the vast majority of plastic gauges it'll be fairly average-to-poor when it's brand new and woeful-to-WTF after you've had it 6 months.

That looks good, and nowhere near as steep as I expected the price to be.

Expert placement in front of the weeds for the photos, incidentally. 10/10.

Does that actually mater? The only thing it really needs to be is consistent so you can get a repeatable tyre pressure and set it how you like.

Surely that assumes whatever you're checking it with is accurate.

Either it's the same range, same problems.

Or you use 2 separate gauges, and if one is inaccurate it just makes it look like the pump gauge is inaccurate at one end.

FWIW my Topeak pump, SKS guage and the old oxford guage all agree to within their stated accuracies.

yeah me too, I wonder how they do it?

😉

I just pump my tyres up to the same pressure every time (I have no idea if 30 and 35psi on my gauge is accurate but it's the pressure I like. Same for the jump bike, 65PSi (maybe the most terrifying thing I’ve done on a bike recently was pumping it up that high when it already felt hard!) and 100/120 on the road bike.
As said above consistently doing it the same is probably more important that getting the number exactly right anyway.
