Got it a week ago and have been testing it expecting I'll want to be familiar with it if I actually HAVE to use it which is what I bought it for- replace 20yr old mini pump for on-road repairs. I've heard people replacing floor pumps with this. No way. It's LOUD!!!!!!!! Louder than the pump you use to blow up your typical air mattress!!! The detachable brass chuck gets VERY warm. But the reason I'm not giving this a ringing endorsement is the amount of trouble I've had getting it to consistently inflate. I've tried on tubes and tubeless. It's very finicky. Will be inflating at about 1psi/sec and then suddenly *stall*. It's still running but something with the chuck seated on the valve isn't perfect. Like you have to hold it perfectly in position. You adjust it and it gets going again but it can be rather frustrating- especially if while trying to get the chuck reseated you've actually LOST 2-3 PSI! I think with practice it will get better. Make sure the first time you use it is not when you really need it! Auto shut-off at preset pressure is great! Same issue with valve sealing makes using it as a pressure gauge kind of hard. Again, might get better with practice. I have only gone as high as 70psi so far. Took 2 minutes because of finicky valve sealing.
Maybe it isn't technically true, but it feels like shock pumps are really bad at their job. No big deal if you'll be filling your fork to 80psi, but topping off a rear shock at a bike park can be a painful experience so bad that you would rather just live with an undersprung shock rather than red welts and blisters on your hands.
This pump is quite long, so it isn't easy to put in your pack. However that length must be contributing to mechanical leverage, because the first time you use it you'll hit your target pressure so effortlessly you'll swear the gauge must be lying. You're still going to need something more compact if you ride with a hip pack, but if you ride with a large enough hydration pack this is simply a no-brainer.
My 1st real floor pump has lasted 25yrs and is still going strong, but it was time to get a 2nd floor pump which I decided on a Lezyne Sport Floor Drive pump and upgraded it with LEZYNE PRESTA PRO FLOOR PUMP HEAD. The LEZYNE PRESTA PRO FLOOR PUMP HEAD makes easy work of pumping a tire with a presta valve. Easy to mount, blended excess air, and remove without applying stress to the valve or stem. Simple to use and a secure seal, you can't ask for much more. It's a great match with the Leyzne Sport Floor drive pump.
I have had the Sport Gravel Drive Floor Pump for a couple of years now. The stock screw on pump head was horrible / awful / terrible / no bueno. This Presta-only head is a beautifully machined product that works very well. At $30 it should be wonderful, and it turned a $50 pump into an $80 pump so it only gets 3 stars for value. But if you have a Sport Gravel Drive Floor Pump (or any other Lezyne floor pump with that terrible screw-on head) and you don't want to just throw it out, this is the fix as long as you only need it for Presta valves. Installation is easy. Just cut the tube as close to the old head as possible, lubricate the inside of the tube, and install the new head.
