I just got this in the mail yesterday, and it looks promising. I say promising because I don't have a new tire to mount tubeless, and a broken in tire mounts easily. It will inflate a 29er 2.1 Ignitor from 0 to 30 psi in 23 pumps. 6 to inflate a road tire to 70 psi, the max this pump will deliver. Think river raft pump meets bicycle pump. Not cheap, but neither is an air compressor. This is faster if you count start up time (and noise) for the compressor, mine being a small Bostitch pancake compressor. :D

Lezyne? I just got their classic pump and am so pleased with it. Of course I too have not tried it on tubeless for seating but just the pure action of the pump and the awesomeness of the chuck is worth it to me.

I have this pump, as well as their high pressure one...it has yet to seat a tubeless set up for me. It's still wonderfully fast to pump up the big tires, but seating them....I think they're pushing it. UST tire with a UST rim may be a different story...but who runs that set up anymore...

I recently bought a Topeak Joe Blow Mountain.
Bonty 29 x 2.0, Zero to 30psi in 10 strokes.

pop my balloon...

Are y'all taking the valve core out? :D Even my BIG stationary shop compressor won't inflate new installations reliably with the valve core in place. I will inflate with a tube overnight rather than fight with a new tire. So I'll try the floor pump but not selling my compressors. The pump is a joy to use I must say.

But is it sexy? Does it make you feel fine about yourself, cause mine does. :D

UST spec / TLR tires and rims do not require the valve core to be removed to seat with a floor pump, even a normal Joe Blow Sport. I do it all the time.

i own the lezyne cnc floor drive and the cheapest craftsman air compressor, i think it was 79 bucks. the lezyne is a great pump but nothing beats an air compressor for setting up tubeless. nothing.
yeah yeah, i don't fight tubeless anymore and time is NOT of the essence, but the noise issue is important to me. And unless you maintain pressure all the time (even noisier) you have to let it air up, which takes time too. I do use all ust wheelsets at this point, not sure what maxxis ignitors and ardents are considered as far as TLR. Like I said, I have pretty much bottomless air available but that doesn't always help.

Those are standard tires, not intended for use without inner tubes.

Half the price and twice the speed is pretty sexy
I always thought expensive and slow was sexy. You can have any two: cheap, fast, durable.

I do not consider the Topeak cheap. The Lezyne is expensive. There is a point where additional cost does not mean better.

The Lezyne pump - valve connector screws on the presta valve head. I have found an annoying issue with the design.

If you use removable valve cores - useful for tubeless - it can back out the core on removal of the Lezyne head after inflation. This of course deflates the whole shebang. I have found I have to really tighten the cores or add a drop of locktite to use the Lezyne.

I personally haven't had a problem with the removable valve cores, but i can see it being a problem in some cases.

I, however, have had a personal problem with the lezyne presta chuck for a while...especially with the high pressure models. When you get up to ~100 psi, the chuck doesn't really want to come off smoothly because of the built up pressure...you have to twist the chuck with the tube, rather than just the chuck spinning off freely. Typical chucks...flip the lever and pull off.

I found if you put some really thin lube in the chuck (it's dry from factory), and also on the valve threads, it works much better and typcailly comes off without a problem

However...problem 2 is with the dirt drive...it's meant for tubeless tires. However...most tubless valve stems don't have anything keeping them from spinning. When removing the chuck, it causes the valve stem to spin, which then breaks the seal at the valve stem. Typically is seals up quickly, but it's still pretty lame. You can hold the valve stem from spinning...but one more annoyance that typical chucks don't have.

It's a nice chuck in some instances, but it's worse than the typical lever chucks on most bike pumps in most instances. Why I bought both models, I don't know...they are sexy?

+1 for the Joe Blow Mountain. Fastest floor pump I've ever used, and it'll even air up a car tire in a reasonable amount of time. I've found the gauge to be very accurate as well, which is a nice bonus. I got mine for under $25 shipped on eBay, so that extra $60+ bucks in my pocket is all the "sexy" I need. :D
