|I have a bike with a GT "triple triangle" design frame. This makes it impossible to mount a full-size frame pump under the top tube: no pump peg, and the seat stays join the top tube at an angle, about 4" in from the seat tube.
Looking for a reliable minipump that'll inflate Presta tires to 100 psi or more, reasonable amounts of time/effort. Thanks.

|The best minipump recommendation I have for you is CO2 and a valve. Tiny, almost no weight, no effort. I've been CO2 only for about 8 years now.|

|The opertaional words here are "reasonable amounts of time/effort". I used a Blackburn mini for years. It fit in my jersey and got tires inflated to maybe 100 lbs. It was a total pain to use. It takes about 250-300 strokes to fill the tire. I finally got fed up with it and bought a CO2 dispenser. I got the Innovations one. It takes 12 gram unthreaded cartridges that are cheaply available at sporting goods stores that sell air guns. One cartridge fits in the unit, I carry another 2-3 with me. This adds up to significantly less bulk than the mini pump.
It inflates tires to 80-90 lbs which is plenty to get you home or to a bike shop with a real pump. The 16 gram cartridges are probably better, but not worth 3 times the cost per cartridge. If I can ride 35 miles home on a 90 lbs tire, so can you.

|Thanks. I currently use the Innovations Ultraflate IH and buy cartridges at sport/hunting shops. Mostly ride in remote rural areas, and would ask Santa for a minipump for additional security, *provided* a decent product is available...|

|I recently bought an Innovations Second Wind -- this is a tiny pump and CO2 dispenser. Frankly, I haven't used it. You can't store a cartridge in the unit and its kinda big. The pump, while small, works. I'd hate to have to fill a tire up with it.
For a long ride, I carry a patch kit, two tubes and 4 CO2 cartridges. I've not been stranded yet.

|I have the same..and swear by it..you can pump the tube up to where its sorta firm then hit it with the CO2. By doing this you dont blow the tube from having a pinch, and you get that extra PSI in there a 12g cartridge doesnt give you.|

|I start the inner tube manually. Really darn easy. I carry 16 gram cartridges. Couldn't be easier and I've never ever considered carrying both.|

|think you miss the point..this pump is a two in one..both manual and co2|

|Crank Brothers Power Pump. A friend offered me one the other day to fill a mountain bike tire (in high volume mode) and it worked extremely well. I'm getting my own real soon. It's very small, and at $20 it's cheap, too.
I use CO2 on my road bike, but also carry a Blackburn pump. Thankfully I've never had to use it because I've had terrible experiences with Blackburns on mountain bikes. I usually end up beating them to death against rocks on the trail.

|a Topeak Road Morph pump (w/out the guage)on the road bike as well as CO2. I have the UltraFlate and the Microflate. I use the Ultraflate for MTB, and the Microflate for my GT. I know the pump is a little extra weight, but to me the peace of mind is worth it. Had a flat once about 3 miles from home on the start of a ride. I changed the tube, pumped it up with the Topeak and used CO2 to finish it off. Had a flat a few weeks later, CO2 cartridge didn't work (user error, lol), and had to use the pump. It worked fine and I wasn't tired afterwards. Hope that helps.|

|I had one of the older models that used a press-on head, and I loved it. Worked great, no problems getting up to 115 psi, relatively fast. Unfortunately, I lost it out of a Burley trailer when taking my daughter for a ride. Replaced it with the new model that has a thumb-lock head. I don't like it quite as well, but it still does the job. At $20, it can't be beat, and it doesn't contribute to landfills.|

|I don't carry any CO2, and manage to pump my tires up to 120 psi with my PVo; a bit of work, but then I'm cycling for fitness anyway. I've only used the PVO once as a test; as I just bought this pump last month. I've used the AirZone pump a lot to put 100 psi into my tandem MTB road slicks, and 80 into my offroad tires. The AirZone is quick, but pretty large to be called a mini pump. I'd check at your LBS and see if they will let you test a few pumps.|

|I have a Topeak Pocket Master Blaster that fits nicely under their aero wedge bag. I've used since last summer and it works well. Up to 115psi, although it does take a couple of hundred strokes. But they are short strokes.
I used CO2 for years but the 16 gram threaded cartridges got too high. And if you are carrying a couple of threadless cartridges and the gadget they fit in, all if a sudden you start adding more weight than a mini-pump. They only reason I would carry CO2 is for a ride when FAST was critical. Otherwise - the pump works well for me.
