I bought this pump and can't seem to get it to work properly. First of all the diagram/intruction is backwards. It says that the unlocked position is when the clip is flipped out, and locked is when it is flipped down or parallel with the pump body. Mine is the opposite. So I attached it and cannot get my tire passed 45psi, the air starts leaking out and it becomes very hard to pump ( a lot of forse is needed). Anything I am doing wrong?

Yes you bought the wrong pump.

You should be able to get the tire above 45 psi with this type of pump but it is very difficult and you won't get it much above no matter how hard you try. The Road Morph has a small hose that allows you to place the end of the pump against the ground.

I have done the same, as what the Road Morph makes it so easy to do, with your type of pump. I would lay the wheel flat and put the end of the pump on the ground. Sometimes the end of the pump sticks out far enough to allow this but you need to be real careful, you don't break the valve stem.

I doubt that you're doing anything wrong. It's just that most mini-pumps are junk.

Thanks, so what pump do I need to buy? (I want to carry it on the bike)

I bought one of the little Schwinn mini pumps at Target. I carried that thing around with me for a good while, and finally had a flat when I needed it. It was pretty worthless. Very little pumping capacity, and I don't think I ever got the tire above 20 psi. I had seen the Road Morph touted on the Road forum for the little high-pressure tires, and wondered what mountain bike people used on high-volume low-pressure tires. Turns out, they used the Road Morph, too. So I got me one, and haven't regretted it. It's not perfect, and I haven't tried every other pump out there or anything, but it's definitely workable.

I can't say whether your pump is better or worse than the little Schwinn that I had, but you may not be doing anything wrong at all.

This thing is rated to pump up to 120psi, what a ripoff!

Like I said, Topeak Road Morph. I made the same mistake as you. The old pump is sitting in my drawer. The Road Morph is attached to my bike.

There is also a Mountain Morph. Same idea but designed for higher volume, lower pressure tires.

BikeGk

This one? Does it attach where the water bottle bracket is? Can the water bracket be attached along with this?

spinnaker

Which one??

But yes, the bracket attaches under the water bottle bracket and yes the water bottle bracket remains attached. At least the one I have.

I had complained the entire summer about my sorry frame pump. I had several flats and had lots of times I had to use it. I have a serfas frame pump. I never could get it to pump up past 65. I bought 3 CO2 cannisters. I had a flat a week ago and wasted the first one figureing out how to use it. so i use the second one to actually inflate the tire. It is hard and I reassemble the rear wheel and ride off. Well somethin is rubbing and I notice the tire is not properly seated on the rim. I had to deflate the tire. I am within a mile of home so i used my pump. I pumped it right up to 120 and still have not added any air. I said all that just to ask if there really might be some secret to using frame pumps successfully?

About the lever thing. I have a floor pump i love. But I was watching my wrench air up tires while we were talking. the lever on his was the opposite from mine. Odd but I was not sure enough to ask him about it. I went home and checked and mine is indeed the opposite.

That's what I was thinking too....how can they advertise this thing for 120PSI and I can't get past 40PSI?

spinnaker

Well you still only posted one link but that is the one you want if you have a road bike. The model with the gauge is nice but not real accurate. The gauge will jump 5 lbs at a time. If you carry a gauge then there is no need to get the G model. I carry a stand alone gauge only when touring. When I am doing day rides, I figure it can wait till I get home for an accurate fill of my tires. The Topeak gauge is good enough for emergencies.

BikeGk

Here is the "turbo" model....is the gauge different than the non-turbo model?

Also, I have another bike (mountain), would this pump work ok for it, or should I get the mountain morph also?

spinnaker

Sorry not familiar with that model but the Topeak website says:

"Same great features as the original Mountain Morph plus a cool dial gauge for perfect inflation every time. "

So I am guessing it is the same as a Mountain Morph (High volume low pressure). So you will be able to fill your tires faster, but it will be much harder to get to a higher pressure.

Ok, so I called my LBS today and told them that the pump was no good...they said it should work fine, to bring it in before 6pm. I rushed home from work, and got their at 5:30PM..... They lied and the store was closed. I was so annoyed that I went home and took the pump apart. The problem is as follows...when you get up to ~40PSI the air from the tire starts shooting out of the pump where a screw is. So I took the head of the pump off and wrapped the body with plumbers tape.....Put head back on and got the tire up to 65psi with not much effort.....then the air started shooting out again. Now I just filled the screw holes with glue and put the screw in...if I can seal off the leaks...this will make a great little pump...either that or the pump will explode in my face!
