Can anybody help me? I'm looking for a mini-ish pump I can mount on my frame sometimes. The ideal location would be right in front of the seat tube and in line with the seat tube, not off to the side. Not on the water bottle mounts (I have none on my seat tube anyways). I would put the bottom of the pump right down by the bottom bracket. BTW it's a steel frame with normal round seat tube, inch and an eighth or whatever.

Other desirable features:

- detachable hose to save the valve stem and make pumping easier
- presta only is ok.
- small but doesn't have to be microscopic.
- inflates to 100 psi in the real world, not marketing.

A topeak morph can mount with zip ties.

What's wrong with a regular frame pump?

Lezyne Tech Drive in your jersey pocket?

If its a steel frame, a Silca or Zefal are the correct answers

I have a couple of those mounted under the top tubes of my bikes. Get a pump peg if your frame is not the right size to get by without one.

yeah don't want a full size frame pump. Too large, too heavy, too rattley. Impede lifting the bike. I have an old Silca never liked it. Jersey pocket ok, but I might want a slightly larger pump than fits well, and on some rides jersey pockets will be stuffed with other things. So I want to be able to put pump on frame. Zip ties? No, then you have to cut them off. I did find this strap with a rubber block that goes between frame and pump, might do the trick: Zefal Bicycle Doodad Plus Pump Strap

Could try that to mount a Lezyne.

Personally I just go with co2. Fits nicely with tube, tire lever and one cartridge in a saddle bag or jersey pocket

Yes maybe I should try this. I like to be old school and self sufficient, but mini-pumps are a pain in the a$$. Pumps do let you change multiple unexpected flats (if you bring multiple tubes or a patch kit) and allow you to partially inflate or top up a tube. But the number of tubes / flats I change on the road (not in my shed with a floor pump) per year is pretty small (like maybe two), so maybe CO2 is acceptable for road use. I'm a treehugger, but a cartridge or two per year isn't much waste. Do you just bring one cartridge and one tube on a ride? Most of my rides are a couple hours through urban / suburban areas with other cyclists around so in the case of the rare double flat I'm not too far from help.

Did it take you much practice to feel competent with the CO2 system?

Easy to use. I bring one cartridge and one tube. Haven't had a flat in over a year, knock on wood. I invest in good tires and check tire pressure almost daily

No, it's super easy. You probably won't need more than one practice cart to feel confident. If you can use a pump or compressor you can use CO2. The only thing is it diffuses out of butyl tubes several times faster than air, so don't be surprised if the next day the tire seems unexpectedly low. Completely empty it and refill with air.
