pump for 100 psi for Bruce Banner
I own LEZYNE HV Bicycle Hand Pump, High Volume 90 PSI. Over the last year I have changed many flats on the side of the road with it. The other day I tested it at home. I was curious how much psi I was putting into the tire. After I pumped it with LEZYNE HV Bicycle Hand Pump I put on the home floor pump with built in gauge. It was only 52/52 ish :/ Enough to ride slowly home I guess.
I am looking for pump Bruce Banner could pump up to 100 psi on the side of the road.

You need a high pressure pump, not a high volume pump. Pumps like yours are designed to pump up wider high volume tires. Unless you have arms like the Incredible Hulk you won't get the pressure you need. High pressure pumps have skinny barrels in order to generate higher pressure. Of course they pump less air per stroke than a high volume pump unless they have a much longer barrel.
My pump of choice to attain high pressure is my trusty Zefal HPX, I can get well above 100 psi with it

I've been using a Topeak Road Morph G on all my bikes for over a decade, and I find I can quickly and reliably get to over 90psi with ~100 strokes.

The answer's easy. (Mounting it on your bike might not be.) The Zephal HPX, a full frame pump.
True story - 45 years ago with the earlier (and slightly harder pumping) HP. At the club time trial I lent my pump to a friend to pump his skinny tires for the TT. He, a 45 yo skinny engineer. Desired pressure - 120 psi. He looked at the pump skeptically. Then pumped both tires to pressure easily.
I used to ride 110 psi, sewups and the only pumps I owned were those HPs; one on each bike. For 17 years.

I have the same pump, but I typically ride at ~60psi. If you wanted to go higher, get the HP.

My lezyne pump is I guess one of the high pressure road models. I bought it back in 2010? After I was over the Topeak mini I had.
I find it works well and easier than the old topeak I had prior and the built in gauge says i pump it 100+ psi. I haven't verified the accuracy of the built in gauge myself however.
I like how it stores in it's little bottle cage mount holder. I like that the hose is stored inside and rubber caps keep debris out of the pump.

Ditto, the high pressure HP pumps. Even a mini-pump like the Topeak RaceRocket HP can reach 100 psi, if you don't mind pumping 300 or more strokes. The small amount per stroke is what makes it possible.
The longer stroke RaceRocket HPX and Blackburn Core Slim are a little easier, needing about 200-250 strokes.
But nothing beats a full length frame pump, other than a floor pump. Or CO2. Years ago I used a Zefal frame pump. Those were very good. My Centurion Ironman has brazed on pegs for full length frame pumps, so I might get one someday. For my carbon fiber bikes I use mini-pumps in those plastic clip-in mounts bolted behind the water bottle cage.
I settle for around 70 psi and just ride normally. That's usually good enough since I weigh 150, as long as I don't bash across potholes, curbs or bricks. I'll top up at home.

OP: Many flats over the last year? You live in goat head territory? If not, sounds like you could use some better tires.

I'm 5' 8" and 120-ish pounds and have pipe-stem arms. I have Crank Bros. Gem minipumps mounted on all of my bikes. There's a switch at the bottom of the pump barrel that lets you choose high volume or high pressure. I get the tire up to about 40 psi using the high-volume setting and then switch to the other setting to reach full pressure.

I find it important to have a floor pump kept at home/garage to easily ensure tires are properly inflated before riding, which seems to prevent most flats. Regular use of a frame-fit or mini pump , in my opinion, makes tube failures near the valve more likely. THe exception is the Topeak style of mini-pumps with a built-in hose to reduce the load on the valve stem while pumping. I have a cheap mini-pump without a hose, but I have not had any punctures on the road so haven't used it yet.

My gf probably has had at least 3+ flats.
We both run gp5000 with inner tubes. I am little over 9k miles and she is at 3k.

Around 100, maybe. I inflate my road tires to about 80 psi, though, and I probably don't quite reach that pressure when I'm impatient to get back on the bike after fixing a flat.

I got the new pump to almost 80psi. I am 145lbs and 55. So I am sure others could easily hit 90 or 100psi with this pump.
my original pump
LEZYNE Sport Drive HV Bicycle Hand Pump, High Volume 90 PSI
new pump I purchased from sports basement
LEZYNE Gauge Drive Hp Bicycle
HV pump
looks new pump is good to about 78 ish..

I think I might return this one and see if I can get another one that I could hit 100psi easily. I know 80 psi is more than enough to get me home on 30 mile ride but I tend to do 70+ mile rides on the weekend. I would just like to fix my flat and continue with my ride instead of cutting my ride short.
