I want to mount a mini-pump on my Tetra-Pro. My Tetra has the mounting screw permanently embedded in the frame, so finding a longer screw isn't an option. I have an older Blackburn model that I was going to use, but there isn't enough screw thread showing to allow both the mini-pump hanger and the bottle cage to be attached (i.e., there's no space left on the screw to thread the nut onto!).
Any suggestions as to mini-pumps that have mounting brackets small enough to work? I searched the forum and found a reference to Barbieri pumps; any other suggestions?
Thanks,
Kevin

One alternative to consider is to get yourself a fullsize pump and mount it along the left seatstay like this:

My topeak road master blaster is an excellent pump and will pump up any tire faster than any mini.....

Don't know if you can still find them, but I have an old American Classics aluminum cages and Performance Bikes mini pump. The plastic pump mount is thin as is the cage mount and I can use an inverted Nylock nut and get all but one thread on.
The pump is not the best, but I figure the few times I do get a flat and I'm not with someone who has a better pump, it'll do.

Due to the inability of a small pump to pressurize a tire to the required PSI, my wife has a full sized Zephal HP mounted underneath the top tube. I had the same pump on all 3 of my Calfees.
While a small pump may be OK in an emergency situation, we ride much longer rides and are often 30~50 miles from our car. Grossly under-inflated tires make for a long day.

I agree with the long pump idea. I happen to have one of those C02 pumps but I have not flatted yet. Currently riding the American River Bicycle trail in Sacramento I could get aid from anyone almost any time of the week I would ride since so many people use it.
I did have a friend with me a couple of weeks ago. He flatted and changed his tube, then flatted again. I found a piece of wire stuck in his second tube. It looks like a sliver from the edge of a hole stamped in the rim. He had no rim tape on his wheel! His pump worked ok to pump up his tire once we borrowed some self-stick patches from a passing cyclist who kindly gave us some.
Flats are inveitable and as luck would have it any time I flatted I was over ten miles from home.
I don't like carrying unnecessary weight on my bike. I carry a cable bike lock, spare tube, patch kit and multi-tool. This is the bare minimum as far as my comfort level is concerned.
I like the seat stay mounting method so I think I'll check out getting a pump that fits there on my bike. I don't like the top tube location since I carry my bike up the stairs all the time and like to have the tob tube on my shoulder. A top-tube mounted pump is on my wife's bike and think it's awkward to carry a bike when the pump is located there.

Take the pump off when you have to shoulder the bike. A stay mounted pump can become dangerous if it gets dislodged while you're moving.
With my wife and I weight is not a critical issue as most of our rides are quite long, out in the country and away from help. So we carry what we think we might need.

Carbon Pump
This is one great pump. Barbieri CarbOne Carbon Mini Pump: The link is to the Performance description. It reads: Quote:
Being prepared shouldn’t weight you down. This revolutionary carbon fiber pump is ultra light and still powerful. Ergonomic handle. Max. 142 PSI. Length: 23cm. Wt: 69g.
The best part is although it comes with brackets to mount by the water bottle cage there is no need for them. It is so light and small you don't even feel it in your pocket. I got it for when I ride my tubulars...now I think my CO2 could be a thing of the past.

Huh? Might take you twelve gazillion strokes, but you can still get 100+psi out of the little pump. I've never actually measured the tire pressure, but the 'ol thumb pinch tells me that it certainly is more than adequate. And, I have "calibrated" my pinch by years of pinching after pumping with my Silca floor pump that has a gauge.
Quote:

The little pumps will not leave your tires "grossly under-inflated."
But, to each his/her own. I would HIGHLY recommend however that you add a strap to secure the long pump to the frame wherever you decide to mount it. All that extra mass can load the handle spring (on rough roads) causing it to release from it's mount and the results can be quite ugly.

Years ago, when my wife first got her Tetra Pro and I still had my Carbon Frames, I thoughtfully installed a nice mini-pump on her bike. She came back from a ride one day with a purple face and veins standing out on her neck. Seems that she flatted and used the mini-pump to re-inflate her tire. Twelve gazillion strokes was entirely too much for her! So the Zephal was bought and installed. After 4 seasons of riding, the Zephal is still nicely in place.
I agree to each his/her own, but in our riding flat tires are the devils own doing and I don't want to add any further to my grief. If we're 50 miles out, I'm facing a long way back after twelve gazillion pumps.  Both my Serottas were spec'd with pump pegs.

twelve gazillion strokes...I've been told a million times to never exagerate!
Anyhow, yes, it does take more strokes. ...but not that much more. For me, the secret to getting adequate pressure, whether it's a mini or full frame pump, is that once the pressure is increased and pumping becomes difficult, I brace the pump and tire against something rigid. I don't use my other hand and arm to hold the pump and stem. I use a tree, sign, bench... and put the tire and pump head against it. I can then use my entire body weight (~133 lbs) to easily reach more than adequate pressures.
Also, another 2-3 minutes to leisurely pump an additional coupla hundred stroke on a mini pump is not gonna make any difference as far as my ride time is concerned, so I don't rush doing it. Hence, no purple face and distended veins ...at least from pumping up a tire :-)
...Think of it a upper body cross training!

This is probably a non-issue these days, but years ago, I saw the de-facto standard frame pump, Silca with Campy head (replacing the crappy Silca pump head) shatter and draw blood.
The metal sleeve was removed (weight weenie thing) and so the end near the head was not as supported. During one of the last few strokes (high pressure), the plastic cracked/broke (where the sleeve was missing) and broken plastic shards cut the hand that was bracing the pump and stem. Not a serious injury, but certainly could have been.

I carry a C02 inflator with 3 cartridges (12g threadless that you can get at walmart for about .50 each). This would be good enough for 2 flats. I also carry a mini pump in the center jersey pocket on long rides that take me out in the middle of no where. Another nice little addition to the saddle bag is one of the little schraeder to presta adapters that all you to top off at a gas station if you are desperate.

I do what you do, Homsie...co2 cartridge and inflator. And now the mini backup.
Originally, I used this because no pump was small enough to fit on my bike! Now the mini pumps are mini-er but I still like the c02 for ease of use...after getting used to it. I wasted a couple of cartridges at first.
IIn my experience, many minipumps are really hard to inflate with. I have clinchers and so only need to go to 110 or so in the best of circumstances. What jersey-sized pump do you find can get you close without you having to kill yourself pumping?

Any pump will do, try the technique I described above in post #6045.

Where's what I carry and it's minimal. I can't think of anything better.
I use threaded cartridges. Expensive, I know, but 2.50$ (online) once in a while is nothing for the convenience and ease and speed. One 16g cartridge fills a tire. Fast. Easy to leave the cartridge on for short little air blasts if you have to nurse a tire home, which I've also done. Three cartridges you're covered.
On mountain bikes I always also carry a mini pump. I use the egg beaters. Seems pretty good and you can switch to a higher pressure (but less air) mode as tire gets full. It's small, light, and the best "mini" I experienced. I used to also carry this in my road bag but I seem to have lost that habit, even though it fits. I need to start remembering to bring it. I've only used the pump to help others.
Anyone else have experience with this pump: likes, dislikes?
Please tell me a better one if something's out there.
I carry in under seat bag:
1 tube
1 patch kit
Egg beaters multi-tool
CO2 inflator shown above
2-3 16g cartridges
Tire levers (depending on the tire)
2-3 zip ties
Mobile phone
5$

I actually use this CO2 inflator Innovations Ultraflate Plus CO2 Inflation System:
http://www.performancebike.com/shop/profile.cfm?SKU=16498&subcategory_ID=4362 because it's capable of using threaded or unthreaded 16g or 12g cartridges. It's quite a bit bigger than the threaded heads that are available, but it does fit in my wedge saddle bag with the tube, patch kit, schraeder/presta adapter, tire irons, and 3 cartridges. I store one of the cartridges upside down in the inflator. Also, I use a 12g cartidge and then I top off with a 2nd 12g cartridge. There is a locking switch that keeps the remaining CO2 for the next flat..works great.
I use a Torelli Aria mini pump. It takes a lot to get the correct pressure, but it's just there for backup. It's more than sufficient to get enough air in the tire and make it to a gas station or limp home.

careful with that homsie...
over time, all the plastic/rubber part of it will start to crack especially if you keep it in a saddle bag. I have one of those before and it blew up right on my hand when I had to use it.
I now carry the one that Nev has in the picture.

Nev, whose is the inflator thing shown in your post? I only carry the top of the ultraflate inflator with the threaded cartridge. Never had a problem in two years, but I appreciate the heads up. However, what I have doesn't look like what is in your picture..

How often are you changing flats my man? I've gone through bad karma periods with flats almost as common as braking, but not in a while -- karma I've surely just ruined by mentioning it.
*makes mental note: buy tubes, cartridges on way home*
And hey! It's still less than green fees or gasoline for the toys everyone else I know enjoys themselves with.
homsie,
I've tried two of those things and haven't been able to deal with either. They never seem to seat right, don't puncture properly, platic threads strip, gotten a handful of CO2, etc. Tried them because I was interested in the less expensive wally world Box-O-CO2. But they never ever worked consistently. For me.

This isn't a frame mounted pump, but it's not a C02 cartrige or "ultra" mini like the Crank Bros that I find frustrating.
Specialized PVO (Presta valve only). It mounts to the bottle cage, like all & I have it on the seat tube one. Never hit it w/ my foot/leg & it can easily get a tire ridable in less than a minute (about 75-80 psi). You can get to 100, but I'm lazy & usually on the way home when I get flats...
I have 2 & think they're the best- & I've tried almost everything else (at least 6 others).

I came across this old post from Nev on CO2 inflators. I have decided to give up my frame pump and buy a CO2 inflator.
I like the one Nev is using because it is small and space in my seat bag is limited. The inflators that use non-threaded cartridges are much larger, except for the Innovations Ultraflate 2, which I can't seem to find in stock anywhere.
The only cheap cartridges I have found are for the 12g non-threaded which I have seen for less than a dollar. Will they fill up a 700x25c tire to a high enough pressure?
The lowest price I have found on threaded 16g cartridges is $1.75 on quantities of 10 or more from Bike Tires Direct. This is only 50 cents more than they sell the non-threaded cartridges version for.
Is there a better place to buy cartridges?

superunleaded,
Thanks for the link but I couldn't open it.
I bought an Innovations Air Chuck SL and so far I am very impressed with it. It is small and fits easily in one of my seat bag's pockets. I don't think any other inflator is small enough to fit.
Also, I found an eBay seller that carries threaded 16G cartridges for $1.25 delivered on a quantity of 30 or $1.58 delivered for 12. I carry three cartriges in my bag which should be enough. If I ever need to take my bike on a plane, I also have a Topeak Road Morph which will strap on to the seat stay.

D,
The link has been fixed.
I didn't attach this to my bike since it's small enough to fit in my back pocket.

Yes, the link works now. I have heard good things about this pump/Co2 combo. I had considered it but decided that a Co2 only option would work for me. I can always connect my Road Morph to my frame if I need a pump.
