I have a Joe Blow pump that is on its third leaking gauge assembly and I am moving on. I currently run a tubeless setup on wide rims (28mm tires) and I see this always being the case, maybe even 30s on the next bike. I also have a city bike with child seat on wider tires that also takes a lower pressure. On my road setup I inflate to 5.5bar (80PSI) and the city bike is around 60PSI.
I considered portable electric infiltrators but was off put by the nose, subpar chucks/heads, short cords and needing it charged. These seemed like they would fit best as all I ever do is top up my TL setup that loses PSI with each day it sits.
I considered a hi pressure floor pump but was reminded how small the usable PSI range is on a gauge that covers 0-130 PSI. I run 75/80PSI on my setup and gone are the days of pumping skinny rubber to 90-110psi.
I settled on a "mid-volume gravel pump" a Lezyne pump (Gravel Pro) that inflates up to 100PSI. The pump is still in transit and thus I have no initial impressions. The purchase wasn't knee jerk but I'm still thinking it over.
It occurred to me after purchase that while there is a greater usable PSI range on this pump, and it should be easier to see the exact PSI, the top shelf model has a digital gauge (crickets). It should be just as easy to hit desired PSI with any other digital gauge equipped floor pump, correct?
That only leaves the increased stroke volume as a plus over higher PSI pumps.
I enjoy paying someone else to seat TL tires and is one of the few things I go to an LBS for. 100PSI should be enough to inflate a air can to seat tires. Comments thoughts?
If you have a digital display on your pump, is this a love hate relationship? How so?
Not sure if this answers your question, but here it goes. I recently got into tubeless, head first, knowing nothing of the technique. Like you, I have an older Joe Blow (Pro). Unlike your's, the chuck on mine does not leak. The analogue gauge, is reasonable, though after recently buying a digital gauge to take with me on rides (in the event of a leak/flat) it's apparent the analogue gauge is off by a bout 5psi. Not a huge deal, but it's not accurate.
I too learned that in order to seat the tire bead on the rim, I'm either going to have to buy a dual cylinder pump, which both Lezyne and Blackburn make, or a compressor. A friend of mine who owns a bike shop "schooled me" on what I need to do for riding tubeless. He advised that I forgo the dual cylinder pump, and buy a home use compressor that will have a hundred more applications, should I want to avail myself of them, than a bike pump, which will do one thing only.
I followed his advise and bought a 2 gallon (recommended size) Makita 1HP compressor. It's the "quiet series", and it is as advertised. Works like a charm seating tubeless tires. It has two analogue gauges, one for the tank pressure and one to indicate the pressure that you are injecting into what ever it is you're working on, i.e., bike tires. I have been advised not to rely on it to check tire pressure on any type of tire, including, car, bike, etc, but to use a hand held gauge, analogue or digital.
For rides where I need to carry a pump in the event of a leak or a flat, I use a Lezyne Road Drive which will do up to 160psi. Cheers.
