What pumps can.............(18 posts)

What pumps can.............Mike Tea

....you guys, or galls, recommend? It's got to be able to pump 100psi within a reasonable period of time.

I need a new one for my new bike. If I go with a long, framefit pump it will be a Silca (nothing else looks as good) but are there any decent mini pumps?

Yes I have a CO2 but at $5 a squirt for a 16g cartridge it's not really an option.

If you want to pump 100psi quickly, there is no substitute for long and skinny. The longer the pump, the more volume of air you can move with each stroke. Since we're talking about pounds per square inch, the fewer square inches the pump barrel has, the less hard you have to push to get to 100psi.

I have the Zefal Hpx 4. Great pump. Tried about 4 different compact pumps and they eventually pumped up the tire, but not before increasing the size of my biceps!! If you find a good one, please let us know!!

They may look good, but after 50 pounds, they start to really get hard to pump. Around 100 pounds, you have to put ALL your effort to get air into your tire.
Get a new CO2 system. Get a system that uses non-threaded 12gram cartridges. They will inflate your tire to about 95 pounds for a 23mm tire and replacement cartridges cost only $6 for 15 of them at Wall-Mart. (Gun Dept.)

I am not a big fan of pumps, I use CO2, but there is a good trick to using a long frame pump. Put the pump head on the tube and then put the wheel on the ground and step on it (slightly) and use your frame pump like a floor pump. It's not anywhere as good as a floor pump, but it's better than trying to push your two hands together while pushing 100 psi thru a pump. Push down instead and let the ground do half of the work.

I havn't used a road bike pump in years.Spoke Wrench

When I did, I used to brace the wheel against a tree or utility pole when the pumping started to get hard. I still just carry an HPX - no CO2 on the retro grouch bike, but the Armadillo tires on that bike are pretty darn flat resistant.
Yes but their track pum kicks ass!nmthe bull

I've had great luck with Silca frame pumps for nearly 30 years. It helps to have a large frame so you can have a large pump, but I find them light weight (175 gm in the 2nd largest length), quick to get to pressure, quiet (no rattles while riding over bumps), not too much work, reasonably priced, and extrememly reliable. As someone else said, you can't beat the physics of it - you trade off volume per stroke, pressure, and the number of strokes.

I've been on rides where one guy had four flats. I can't see CO2 unless you always ride in groups, and I freqently do long solo rides. Zefals are heavy and rattle a lot, with relatively small stroke volume. I've no personal experience with other pumps, but IME the Silca Impero is a great frame pump.
SKS makes a similar one that's at least as good.dzrider

I like either of them better than Zefals for the same reasons you do.

I like my Silca. It's 17 years old and still works fine. I guess it depends on your strength, but I don't see it as an issue as long as you can get it up to pressure. I mean, it's just a minute and your legs are getting a zillion times longer workout ridign, what's the big deal about using your arms some? At least that's how I think. Just attack it like a sprint and you'll be done in no time... less than a minute I would think, certainly faster than a mini-pump. I'm not particularily strong at 145 lb, and I don't do any upper body workouts.

I haven't had a need to try a CO2 system because what I have works fine. I think that it's wasteful at least by my standards... not only in materials. I'm wouldn't even think of paying $6 to get my tires pumped up 15 times. On the other hand, I wouldn't mind pumping up 15 tires for other people for $6 at a rate of about $25/hr.
Silica frame pumps suck - is that cos they're full of sand?;) nmcharlieboy

I got tired of pumping a tiny pump and saving a few grams.
I got this one because it looked good - good thing it works Great! I carry CO2 only on group rides, for when people are waiting on me. I hate to see when somebody pulls out a tiny pump, cause I know where going to be there for a while!

If 2-3 minutes is reasonable periodof time from your point of view then SKS Teleskop minipump will serve good. It is small (fits into pocket), ligh (95g) and works good. I am able pump 23mm tire to approx. 100psi in 2 minutes using it.

Have I metioned that it is cheap (in 10$ range)?

This thing is amazing...not the most attractive medium-sized pump in the world, but it's almost as good as a floor pump in terms of efficiency and ease of use. I was big Blackburn fan, but this thing makes those last 20 lbs of pressure a piece of cake. It comes with a bracket to attach to the top tube. Available online from many places, including REI and Colorado Cyclist.
