    Crank Bro Pumps

    i was looking at the crank bro pumps...does anyone have one of these that attach to their frame via the WB cage bolts? Do you have pix of it? what's your impression of it? all that good snaz

    I have the Crank Brothers palm sized model(clear) It is an amazing pump for it's size. I used it twice last year with 700x23 tires and it got me home from about 10 miles and 20 miles.
    I'll guess that I got about 80 lbs. air pressure with not too much effort.

    I also have the ToPeak Road Morph pump; which morphs into a floor pump. It has a air gauge and will pump to much higher pressure.

    I carry everything in a messenger bag and only caged water bottles on the bicycle.

    I had the power pump alloy. First time I used it I bent my valve stem. And its hard to lock onto the valve. I now use a blackburn air stik.

    I have the Crank Brothers Power Pump and man do I regret buying this one. I bought it for road use and it just can't get the job done at road pressures. Too much pumping involved. Maybe it will be better for the MTB I am about to build. Basically it works but to get any volume of air you have to pump and pump and pump. Luckily I use CO2 primarily so I use this pump to start tubes for installation and would use it if I ran out of CO2 to get me home (probably at a lower pressure).

    I had the larger metal Crank bros. pump. The one that mounts on the water bottle mounts. I gave it away. It is too hard to hang onto while pumping and it does not go very high with out a lot of work. You can do better. I still use the small plastic Crank bros pump on my mtbs. I like the size and can be happy with 35 or even 25 psi to get home.
    I carry co2 also. I use the pump to get up to about 10 then dump in a cartridge. Even if one fails I have the other

    i have the larger alloy pump, so far i've been pretty happy with it. it has a guage, and the two pump modes (high vol. and high pressure) are super. i also like the fact that i don't have to take the head apart to switch from presta to schrader. i haven't had any issues with getting my tires up above 80psi with regard to effort involved. takes me about 5 minutes to pull my wheel, replace the tube and get rolling again when i flat...depending on where i'm going it might take me longer (if i'm going to work, it'll take me about 7-10minutes) .

    i used the blackburn airstick for a while, and it was okay. but it died on me on a hot day while i was out in the hills. thankfully, i think it was a holiday, so there were plenty of other folks out on their bikes, and i borrowed a frame pump. i vowed then, that my next pump would be a frame pump, but then i got the crank bros. one and i'm pretty stoked on it.

    my two complaints about it are 1) you can't use it to inflate an air matress (but seriously, what bicycle pump can do that?), and 2) it sometimes slips off the valve when the pressure gets around 60-80psi, but that just could be due to the fact that i don't have the valve head tight enough. it's not enough of a problem to make me regret getting the pump though.

    bending the valve stem is not the pump's fault...you have to be smarter than the valve stem and/or pump to make it work. what's so hard about putting the pump on the valve and twisting the pump body to lock it on?

    It was my first time using a presta valve and the pin bent. I guess it was just a newbie moment but it was annoying.

    The laws of physics can't be broken regardless of who makes the pump. It all comes down to volume and pressure.

    Long skinny pumps work best for road bikes. You need a small diameter so that you can pump 100 psi with reasonable effort and a longer stroke works best to get enough volume to get there with a reasonable number of strokes. A Road Morph is the ultimate road bike pump because it's big enough to provide significant volume and is designed to let you use your body weight to get high pressures. Only trouble is that they're ugly.

    Fatter pumps work better for mountain bikes. If you're doing real mountain biking, 40 psi would be a lot so most guys can pump that easily. You've got a much larger volume tire, however, so you'd like a fatter pump to get more swept volume.

    The question to ask yourself before buying any mini-pump is: "How's your temprement?" One way to look at it is that when you get a flat, you're already aggrivated and a pump that takes more strokes and time is going to increase your aggrivation. Another way to think about it is that you don't have a flat very often so the advantage of a mini's small size and weight will outweigh it's inconvenience on those rare occasions when you have to use it.

    I like my small bicycle air pumps but Nashbar has frame pumps available which are much larger and ACME bicycle Company in Kansas city. I believe will Braze on pump pegs to your frame if you send it to them.I forget whether it is KC Mo or KC Kansas

    I have a crank brothers minipump with a selector for hi volume or hi pressure. Yeah, right. It is ok to 70psi, but to get to 100psi walking home would be quicker....it also looks like you are doing something rather unsavory to passing view.

    but at least you know that it's 70psi. with something like the blackburn airstick 1, you have no clue what the pressure is, because it doesn't have a guage. and mine never worked properly (something was screwy with the way it took air in). in my experience, the crank bros. alloy pump is a better pump all around. smoother to operate, dual valve heads, and dual pressure settings (yes, it makes a difference).

    all i'm saying is that after using both the AS-1, and the crank bros., i prefer the latter.
