Making a hose adapter for a frame pump sounds like an excellent idea to me. So much so, that I don't know why there aren't any actually for sale pre-made. You could make one really fancy, with built in pressure gauge, and plastic "floor-pump base" clip to turn your frame-fit pump into "floor pump lite"...
I sense entrepreneurial opportunity here... |

I've never computed the cost of CO2/cylinder because I don't use many of them. I didn't realize CO2 escapes the tube faster than air, but it always gets me home to my old faithful floor pump.
CO2 does diffuse out faster than air but it's not important over a matter of hours, just days. When I use a CO2 cartridge to inflate a replacement tube, I deflate the tire after I get home and refill it with my floor pump. |

the OP is looking for a way to top off his tires routinely without buying more floor pumps so that's why I conluded you were recommending CO2
Thank You Sir! <sigh> I hafta wait until tomorrow to see if this works. |

The trick to using hand-pumps and not busting the valve is to grab a spoke or two next to the presta valve along with the head of the pump. Then any motions introduced with your pumping hand moves both the wheel AND valve-stem in unison. Then there's no movement of the stem relative to the rim.

"I do have a floor pump, but only at 1 of the 3 possible locations by bike could sit for an extended period of time, so there's a 2/3 shot I'm using a hand pump."
Just goes to show how missing one sentence can interfere with "on-topic conversation". My bad. |
I apologize for not carefully reading the whole thread. I just want to make two comments and hope they're helpful.
Like others have said, there are small/mini/frame type pumps that have hoses. I have one that is larger than a mini pump, but smaller than a frame pump called the Morph Road G Master Blaster. I can mount it alongside the seat tube bottle cage. It is like a mini floor pump in that it has little fold out legs to put your foot on, a fold out T handle and a short length of hose. I have it on my cross/commuter bike, but also use it when I travel with my road bike because it's smaller than a floor pump, but will work fine when I reassemble my bike after shipping. The other point I would make is if you have two or three regular locations where you need to air up your tires before riding, buy a couple more floor pumps. Really, the cheap ones (<$25, more like <$20 ) work just fine. I have, I think, 4 floor pumps in that range that I keep in my garage, my car, my office and my wife has one in her car. I start rides from all three of my "locations" regularly and don't want to have any excuse not to top off the tires every ride (that's the only time I get flats pretty much is if I get pinch flats). It really is worth it for the convenience. It's not like you'll wear them out! Some of my cheap Performance or Nashbar house brand pumps are pushing 15+ years and work perfectly in all respects. |

While I agree there is no substitute for a floor pump, my girlfriend is not going to let me put 1 more thing in her restaurant (already pushing it with the bike). And I'm a lover of those lovely phrases that have led so many to greatness: think different, add lightness... and 4 pumps when 2 will do is tweaking my inner German (I'm not German, I just think like one), the land where if you leave your front yard light on all day, you neighbor will let you know. |

You missed the opportunity since the Topeak Morph are just what you describe. Too bad. Better luck with your next idea. :cry:

I don't know of any available hoses with presta fittings, but there are plenty with schreader fittings, and there are adaptors to convert schreader to presta.
Good for up to about 100psi, but the cheap little hoses tend to die after a bit.

BTW- you really don't need a hose if you improve your pumping technique. Most people who break valves do so because they don't properly brace the pump to the rim. Try holding the valve end of the pump, with your thumb extended down to the rim for support so that end of the pump doesn't move. Also use that hand to pull the the wheel or whole bike off whatever it's leaning slightly so it can move with the pump if you're not as steady as you hope. Either or both techniques will effectively make broken valves a thing of the past.

Totally
Freaking Works I started with tires at ~ 90 psi (they're x32 so 100 psi max) and went to town and it held with no qualms. So if you hate your minipump and don't want a trail O pumps wherever you might store your bike, this will make any schrader compatible pump do whatever you want without risk of damaging the valve. Only 'meh' part is that both my minipump and this replacement have to be slightly disassembled to change valve types, so one might want to investigate the 'twinhead' version here: http://amzn.com/B000FI6XF8 |
