Floor Pumps for MTB tires!!!

I have two digital gauges that read consistently the same pressure. My dial Accu-gage always reads 3 or 4 psi lower than the two Digital gauges.
I trust the digital gauges more.
.
I have the Bontrager Turbo Charger HP Floor Pump. Long hose, the gauge is up top, and the airchuck works good, latches on to presta without fail and isnt too big between the spokes.

If I was to buy another pump ( and it was on sale...) I'd get this
LEZYNE ALLOY OVER DRIVE

I think what is most important is repeatability. Always use the same gauge when you can.

I don't know how accurate my gauge is (though I am pretty sure it is within a psi). But I always use the same one so always get the same results.

Agreed. Until you get to the trailhead and need to borrow a pump.
Or brag about running 14psi when you're actually at 18. :rolleyes:

I only say that because you can't trust your friends guage. Yours may be perfect, but theirs totally off or vice versa.

My pump is off by roughly 5 pounds, depending on the day. If I have to go by pump only, I just go by feel. That said, I still haven't figured out my new bike and it's current tire settings (which I am sure will change with new tires), so it's just a SWAG anyway.

That is the pump I use, I replaced the stock guage after it broke 3+ years later. But I throw that pump in the back of car and take it everywhere, so I dont blame Lezyne for that, but the digital gauge is a sweet upgrade. But I do use the dual-valve head, cause the new Lezyne quick-chucks weren't out yet at the time. :http://www.lezyne.com/product-dpumps-acc-dualvalvehd.php#.WbxWdciGOUk

The Lezyne floor pumps are my goto and you can repair any part on them too.

Nice pump, but did you read this?

>>When using the Pressure Over Drive as a regular pump, air has to fill the chamber before it will start to fill an empty tire/tube. This may take numerous strokes before the tire/tube begins to inflate. When topping off a tube/tire that already has pressure in it, the chamber will have to reach the same pressure the tire/tube is at first before it will begin to inflate it further.<<

Read the directions??? I cut them off the handle and immediately threw them away! And then it took me a minute or two to figure out what the pump was doing. :oops:

I have a mixed reaction so far. The pump is almost effortless to use as a normal pump. It makes my old Performance special look like a dinosaur. To pump the holding tank up to bead seating pressure, though, is a little tougher. Not too tough, and the floor grips help, but it's a workout to do it more than once. The shaft and handle seem pretty sturdy, as does the overall construction. This is a plus, considering how close the pumper's face is to 220 pounds of compressed air.

The first tire I tried to seat was a Continental Mountain King 2.4 on my 20mm Dt Swiss front wheel for the Highball. 5 tries later, complete with soapy bead for tries 3-5 and it didn't go. I was bummed. I will clean the bead on the tire, and try it again.

Then I thought that maybe something was going on with the tire/wheel combo. I grabbed a Racing Ralph 2.25 off the wall, pumped the tank up, and seated the tire in .25 seconds with several loud pops! Faster than the CO2 method. :eek: Dumped in some sealant and rode it for the Thursday night Black Star social.
