LezynePressure Over Drive with ABS1 Pro(Return to Product Page)

I purchased this pump to seat tubeless tires on my gravel bike. I soon found out that the chuck included with the pump does not thread on to a valve stem with the core removed. My experience has been that when reinstalling a tubeless tire that has already been used for a while, you almost always have to remove the valve core to get enough air flow to seat the bead. Once I got the Lezyne tubeless chuck to use with this pump that process has been easy. But I should not have had to buy the tubeless chuck separately.

Just switched to tubeless tires and this pump makes mounting them easy.

Didn't know I needed another pump, but it was worth it.

Lezyne screw on valve and pressure release are my favorites on tire pumps.

The air chamber helps a lot with getting the bead to set when going tubeless.

I didn't look close enough to see that it is a screw-on valve connection - not my favorite. I prefer a quick-release for day-to-day needs, but the screw-on works fine for when I have to seat a bead.

I can't figure out how to use it come on they don't give any directions on how do use it

Bought the Lezyne Pressure Over Drive with ABS1 Pro; analog version. Now I have an easier time seating my tubeless tires onto the rim. Should of bought this in the first place, instead of the Joeblow Sport III, What was I thinking???

Practico y rapido al inflar llantas.

Bought this primarily for tubeless set up and it works great! It will only thread onto a valve core, so for tubeless just remove the valve core and hold the head onto the valve stem, flip the switch, and it will seat first try. I did four tubeless tires within 10 minutes without any issues. Because you do need to build pressure in the chamber before using it as a regular pump, I still use a different cheap floor pump for regularly topping tires up. Though it only takes a few extra pumps if you want to use this as a "normal" pump too.

Brought this to help seat tubeless tires and because it has a threaded chuck head .

The high volume canister works well for seating, pump it up to 90-100psi, flip the lever & tire bead pops. Release excess pressure & you're ready to inject sealant.

Pump barrel is rather narrow compared to most other pumps & requires a lot of pump strokes to get up to pressure, thus only 4 stars.

Lezyne never disappoints. There is a learning curve as instructions are not the best, but youtube videos help you understand how to set the tubless tire before adding sealant. Tip, remove valve core, of course, from wheel valve, after installing tubeless tire. Then you cannot 'screw' on the head valve, although it seems odd, you simply hold the pump to the open core until the tire 'pops' adubily into place. then, add sealant at a 45 degree angle of the wheel, so that the sealant can flow down the interior of the tire, replace valve core, inflate, and you are done! Super simple. And as a daily pump it is nice and the inflation gauge is at the top, vs at the floor like so many, so easy to read. Great quality product, cannot go wrong if you do not have an air compressor and do not wish to waste CO2 cartridges for setting tubeless tires at home.

Worked OK and then seal gave out after about 10 tires were inflated with the pressure system.

I do not recommend this product

Excellent for all tubeless tires. Works fast to

Not loose sealant. Might need another set of hands.

This pump is designed extremely well. I really like the way this pump feels, it is stable and light. A good combination of capable and portable.
