Anyone use Lezyne floor pump on schrader valve?
I'm thinking it's about time to stop messing with my cheap pumps and get something better. I love the little air bleed deal on there. Overinflated, bleed to pressure.
Except! From what I read, you have to unscrew the church when done. Brings back visions of my youth trying to get the pump unscrewed before all my air leaks out!
So I'm wondering dose this work he same way, unscrewing wwhile all the air rises out?

I have a Lezyne pump. The air that leaks out should in theory be from pressure built up in the hose. The Schrader valve should close almost immediately once the hose pressure is released.

Lezyne! great pump
My lezyne alloy floor pump is used on presta and schrader vales all the time. It works just fine on both. Yes, the schrader seals quickly when pump chuck is removed. The air you hear rushing out is the pressure in the hose. Make sure you seal tightly when reversing the chuck from one to the other.

I've got a Lezyne Micro Floor Drive frame pump, which I love. It works on Schrader valves with no issue. The air bleed valve does work differently on Schrader vs. Presta; on Schrader valves it will let air from the tube, on Presta it lets air from the hose.

Thanks guys! Sorry I should have asked in the original post. Pumps with the newer ABS-2 Chuck. From the directions, it's a quick release from the presto valve and a screw on for the Schrader valve.

I just got one with the ABS-2 yesterday and used it on both schrader and presta. It worked well for both of them. I took a second to figure out what I was doing, but after I did the quality of the seal and how quick/easily it disconnected from both was nice. Im glad I paid the extra bit of money for this. It seems this will last me a very long time.

It's not really an issue. On my bike I use a Topeak RaceRocket HP with threaded chuck. Takes 200 pumps to get my 700x40 tires up to riding pressure, closer to 300 with my skinny road bike tires, so I don't want to waste any air pressure.
My Nashbar Earl Grey floor pump works great and is fine for the money, but I'd rather have a threaded chuck. The clamp-on type is tight but awkward on this particular model, and there's no bleed valve like the Lezyne. So I overpump a bit and check with a handheld gauge that does have a bleed valve.
