Lezyne Classic Dirt Drive Floor Pump $75.00
Like a compressor. Just smaller, quieter, and less expensive.
Simple, easy, straightforward; classic. Lezyne's Classic Dirt Floor Drive Pump takes the features of the other high-volume pumps and pairs them up with an economical wood handle, and steel barrel and piston.
Lezyne high-volume (aka mountain) pumps are different from their high-pressure (aka road) brethren. Larger diameter barrels for more volume, larger connections to move the air, larger diameter hoses to put that air into the tire faster, and pressure gauges that read lower pressure more precisely. This moves double the air per stroke and makes it easier to seat tubeless tire beads. The Dirt Floor Drive Pumps have a barrel with a 37mm interior diameter to get more volume in fewer strikes and a 2.5in pressure gauge that reads up to 70psi.
Otherwise, the pumps in this lineup are the same. The rubber hose is 43 inches (130cm) long. At the end of the hose is a flip-thread chuck, a reversible head for both Schrader and Presta valves. It has a button for bleeding air, which is called the ABS (Air Bleed System). The pump comes with a Speed Chuck, a thread-on slip-fit Presta head with a 90-degree angle to easier set the chuck.
The Lezyne Classic Dirt Floor Dive Pump measures 7.9 x 9.8 x 26.2in (20 x 26 x 66.5 cm). The handle is 9.5in. The interior diameter of the barrel is 37mm, which means the pump has been optimized for high volume applications. It has a claimed weight of 3.6lbs (1.6kg). The color is Gloss Black.
- Barrel, piston, hose, and connectors are oversized to deliver double the air flow per stroke to quickly fill tires and seat tire beads on tubeless tire systems
- ABS flip-thread chuck allows quick and simple air pressure adjustment
- Oversized gauge is precise and easy to read
Reviews & Community
Works (and looks) great!
- Familiarity: I've used it several times
I snagged this fancy floor pump to throw in my truck and top off tires before I ride, based on excellent reviews on other Lezyne models. It did not disappoint!
This is a "high volume" version, optimized for MTB tires. They aren't joking that it puts out a lot of air in a hurry... I was able to install Stan's tubeless system on my wheels with this pump rather than an air compressor.
Unlike the other reviewer, I've had no problems removing the valve core, but then again I always remember to use the bleed button before unscrewing the chuck. But there's really no need to use the threaded chuck if you've got a Presta valve since the speed chuck works fine and saves the hassle of screwing the chuck on... just press it on, pump up, bleed the hose, pop it off. I think the other reviewer must be missing an O-ring for his speed chuck if it falls off, or have an odd sized valve.
Bottom line is this pump feels well built, looks great, and puts out a lot of air in a hurry.
Great Pump Except for Chuck
- Familiarity: I've put it through the wringer
I know, I know: it's kind of like saying the restaurant was wonderful except for the food. This pump does move a lot of air quickly and the gauge is very easy to read. However, I hat the chuck options. If you use the threaded chuck on a presta valve with a removable core, you risk removing the core while unscrewing the chuck (I've done this several times). If you use the speed chuck, you have to hold the chuck onto the valve while pumping. This gets the job done and I'm not going to rush out and by a different pump. The construction and quality are very good, but the design of these Lezyne pumps makes me think I won't get another one.
