everything i needed to survive a day on the road fit into my small underseat bag. everything except a pump, which i still had to attach to my frame. no more! now i can fit a pump, a tube, and all my tools into my small underseat bag, thanks to this crank brothers gem. i've tested it for ease of use, and it's simple and it works GREAT, in both high volume and high pressure modes. you're not going to fill up a tire in 30 seconds, but you weren't expecting to, i hope. what you ARE going to do is be freed from the burden of a frame-mounted pump, and have a far more slimmed-down daily load.

This thing works much better than my last emergency pump. I wasn't certain how the adjustable pressure knob would work, but it's actually pretty handy. The ideal procedure is to use high volume mode initially to rapidly fill the empty chamber, and switch to the low volume mode when it becomes too difficult to continue.

If you find yourself having trouble inflating a tire with this pump, make sure that you have the proper pressure selected!

This is a bit larger than absolutely necessary due to the double valve system, but that's nice to have if you've got different valves on different bikes and don't want to buy multiple pumps.

Works as advertised. It will get you through if you only need less than 100 psi. For high pressure tires, it is meant purely for repair on the road (to get you home). It is very hard to push when the pressure gets high, but that is expected. Good pump to keep with you!

I got this pump as a gift, and recently started carrying it as a backup to my frame pump. It works, but it takes a lot of time to get a Mt Bike tire inflated, and a lot of effort to get a road bike tire up to pressure. But it does work on both types of valves. And in high pressure mode, you just have to pump a zillion times to get the tire inflated. But it beats walking home.

I'd buy this pump either as a backup, or if you very rarely get flats, or you can call someone to come get you. Otherwise get a larger pump.

I like this pump, but as has been mentioned before, it is not especially easy to use the first couple of times. What directions there were are rather vague, and it took me some time to figure it out.
That aside, the pump works well, and is small enough to fit in the under-seat pack on my second bike. After buying this, I opted for a frame-mounted pump for my main bike. Nothing against the pump, I just felt that having to hold it completely still while pumping was a bit too much of a hassle.
Well worth it for the price, just do your homework.

This pump is small so it fits in my repair bag. Since I lock up in the city and also have several bikes, it's better for me than a longer frame pump.
Like any mini, it's a lot of effort for a little air. However, the volume/pressure setting at least gives you the option of running out of strength or patience trying to get a tire up to pressure. I usually run out of both around 50 psi, which is fine for my mountain bike and acceptable for my 1 3/8 tires.

This pump has to be the smallest! It works perfect in high volume and high pressure. Going to get a good work out but should be used for emergences.

Truly pathetic. It works fine up to a certain (low, maybe ~50psi) pressure level, but after that, all it does is consistently let the air OUT of the tire. It's not built well enough to properly lock onto a presta valve. I thought it might be ok for emergency, or backup, but for something to be an adequate backup, I'd need to actually be able to rely on it. And this pump is the epitome of unreliable.

I thought I knew how it worked. But when I had a flat I couldn't get any air into the new tube.

I got it to sort of work one time. But, when I removed the pump from the valve, all the air pressure was lost.

I bought this pump to accompany me on road rides. I assumed it's compact design would require more pumping but that it's dual pressure mode would still allow me to get enough pressure in my road tires to get me home - not so! I've tried multiple times to get this little pump to work, but as others have reported I was only only able to get 40-50 psi in the tube and then all it did was let air out! It is a pretty low feeling to be miles from home with a flat, a new spare, and a pump that just won't work. My pump is the version without pressure gauge, but otherwise identical to the "Crank Brothers Power Bicycle Pump" shown. A total waste of money IMHO. A decent compact pump is a good idea for anyone who regularly rides, but this one is not it. Sign me 'Looking for a new pump'.
