Lezyne pressure overdrive micro floor drive xl tubeless pumps high volume-10

With all of the plus tires, fat bike tires, and bigger tubeless tires going around, it may be time to upgrade your pump soon as well. Typically designed for high pressure or high volume, the latest crop of tires push high volume to the extreme. Adding to the few fat bike hand pump concepts we’ve seen recently, Lezyne unveiled their new Micro Floor Drive XL in Taipei. Sized to fill fat bike tires with ease yet still fit in your hydration pack or frame bag, the pump is also joined by the new Pressure Over Drive which should be handy for seating tubeless tires…

Essentially a supersized version of the Micro Floor Drive, the new XL version runs a massive barrel to up the volume of each stroke substantially. Other than the increased size, the pump remains the same with a fold out foot peg and flexible hose with a reversible presta/schrader head with pressure release. When available the pump should run around $50.

Lezyne is also joining in on the tubeless inflation floor pumps with an air chamber equipped floor pump of their own.

The new Pressure Over Drive was shown in Taipei in prototype form so a few things will likely change for production like the pump head and the base. But the overall concept will remain the same with a large chamber that is filled with the pump, then released with the flip down lever below. Likely to be sold in black with a wood handle, the Pressure Over Drive will sell for around $129 and should be available in June.

      When the threads don’t align properly (you’re screwing it in on an angle) the threads can strip. If you screw the head on straight (ahem!) then you will have no issue.

    Complete agree with Ryan. Okay, I can see the reason for a high pressure gauge on the chamber side, as you’d want to pump the chamber up to 150 psi or something like that to get that burst of air, however, once the bead is seated, I’m never going to read higher than 35 PSI on a MTB and about 15 psi on a fatbike. Expensive quality gauges have an error of about 2% at full scale, so for a 160 psi gauge you have an error of about 3.2 PSI, which on a fat bike is HUGE, and typically accuracy of gauges are pretty piss poor at the low end of the scale. For a MTB, this gauge is worthless. The much better system would be to have two gauges that you switch from on to the other.

    I have the bontrager flash charger. Works really well. Gage goes to 160, nice burst of air that has seated 4 tires so far, two weren’t tubeless. One of those took 4 busts at max psi to set up. Upper body work out on that one but when you don’t have access to a compressor the flash charger is awesome! Can’t say how well it would work with fat tires? Biggest I’ve set up is 26×2.5.

    They may need to have a guage that has a higher limit so it doesn’t break when you release the pressure in the chamber.

    MaraudingWalrus – I’m right there with you. Ran through a couple of heads with regular use of my Dirt pump. Lezyne was cool about, sent me new head assembles, but also stated their speed chuck heads “aren’t for use with threaded valve stems”. Not sure how many of those exist in the MTB tube/tubeless world…

      I said the same thing but traveling made me buy a tubeless floor pump. I still use a compressor at home. Funny that you can buy a nice compressor for the same price as a floor pump. Par for the course when comparing bike stuff to non bike stuff.

    Awesome! They both look nice! I have the micro floor drive but would consider the XL as well, especially for the fatbike. The pressure overdrive looks great as well, and would be the ticket for traveling. Its not going to replace a compressor, but if your buying a new pump, I would definitely be interested in this for setting up tubeless when away from home. Why wouldn’t you want the ability if you run tubeless? I agree about the gauge though. I would love if they made one that maxed out at 30 or 40psi and gave a much more precise and reliable reading. Its hard to depend on a crappy gauge, or to be precise in the low digits when the gauge goes to 160.
