Lezyne believes that road and mountain pumps should not be the same; the two disciplines call for different tires and different pressures. As a result, they've optimized their road designs for high pressure and their mountain designs for high volume. Lezyne's mountain pumps have 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 CNC Dirt Floor Drive Pump has 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.

The CNC Dirt is the top of their high volume pump line. It is comprised entirely of CNC-machined aluminum parts. The handle, the piston, the barrel, the base are all fabricated this way. It has a secondary benefit of being lighter than their other pumps.

Everything else in the pump is designed equally well. 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 CNC 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 3.4lbs (1.56kg). The color is High-Polish Silver.

  • CNC-machined aluminum is lightweight enough to be easily tossed in and out of your truck, but durable enough to withstand years of use
  • Reversible head threads to Presta or Shrader tubes, ensuring zero air loss during inflation
  • Oversized, 2.5-inch gauge remains easy to read, even in the fading forest daylight

Seat a tubeless bead effortlessly

    This isn't my first experience with a Lezyne product so I expected the best when purchasing the CNC Dirt Drive Floor Pump. The pump did not disappoint. If you have ever tried to seat a tubeless tire with a floor pump, you probably know that it is generally an exercise in futility if you don't have an exceptional pump. This pump will seat a bead no problem. If you prefer and generally use tubeless tires, this is the pump for you. It is expensive and worth it. Lezyne products are well made and this pump will give years of use.
