Posted my new electric pump and some people were concerned with how heavy it was so I did some comparisons. Just a kitchen scale so not super scientific but maybe helpful to some for reference.
The small Specialized pump is the lightest by far but I was measuring about a half a PSI per pump stroke out of it. Not something I’d want to fill a tire with.

cyclists: 1600m climb up mount ventoux, nice, sign me up!
pump up a tire with my bare hands? what kind of animal do you think I am!
A typical fart weighs around 0.05 grams.
I think you need to take into consideration the calories you’ll burn with this hand pumps. Maybe take off .01 grams per 100psi filled.
When it comes to air options, I always think back to the worst times I’ve had sitting on the road side. Once I flatted in sleet that was coming down so fast it was washing over the top of my rim, after changing the tire in the freezing sleet, golf ball sized hail started hitting me as my hands started shaking so hard I was having trouble pumping air with a Lezyne micro pump.
Another time it was 120 degrees and I flatted 4 times, due to goat heads.
What I’ve learned is to double up on your inflation sources. I use a Cycplus and CO2, I used to use a pump as my backup, but I’m done with people giving me funny looks as I’m bouncing up and down on top of my bike laying on the ground. It’s bad enough wearing spandex, but I don’t need that kind of reputation.
I love my electric pump – as a gravel rider, I use it all the time.
But I carry a spare CO2 cart just in case I forgot to charge it.
carry all three on my gravel bike, CO2 plus e-pump on road bike, CO2 plus pump on mtn bike.
I carry the Nana pump: [https://www.renehersecycles.com/shop/equipment/tools/nana-ultralight-carbon-minipump/](https://www.renehersecycles.com/shop/equipment/tools/nana-ultralight-carbon-minipump/)
Its like 25 grams. That, and two TPU tubes, and I’m at less than 100g for all my flat repair stuff.
I have a frame pump. It’s really not that heavy and matches the vibe of the frame I have. The lezyne mini pump broke on me. I’ve had a co2 fail more than once. Frame pump just works.
That lezyne pump can go eat a dick. I used one. They have a metal thread feeding on a plastic insert. Terrible idea. If you use it more than 3 times the threads completely ruins themselves and it becomes unusable.
I have a Giant pump for mtb tires. Small but high volume. No idea what it weighs. Don’t care. It works great.
Worth mentioning that only one of those options has a gauge…
For reference guys, the standard deviation of these weights is the weight of 11 pennies (US$) or five quarters.
Anyone remember the last time they forgot to put their pump in their frame bag, crushed all of their PBs and then realized it was because they were 100 grams light? Me neither.
Until they inflate like 4 – 8 tires (most seem to be 2) on one charge it’ll be a pump for me.
