Regular readers of this blog know that I only review products that I’ve actually used myself in “real world” conditions. Unfortunately, most of the time when I review tire pumps or CO2 cartridges I have to test them out in my garage since it is hard to know when you are going to get a flat tire. However, the first ride I took with the Lezyne Alloy Drive High Volume Hand Pump I got a puncture just six miles away from my house! This pump is easy to use and far exceeded my expectations.
I bought the medium-sized Lezyne Alloy Drive pump for my Surly Necromancer Pugsley—a Fat Bike with massive 4″ wide tires. Fat Bike tires usually run at very low pressure (10 to 15 psi on off-road trails; 5 to 7 psi on sand or snow), but they do require a high volume of air. Most bicycle hand pumps are designed to work the other way around (high pressure, low volume) and they would take forever to fill up a Fat Bike tire. A high volume pump like this one will fill your tires is 30% less time than most other pumps.
The Lezyne Alloy Drive pump is made with CNC-machined aluminum construction, which makes it very durable and extremely lightweight—just 4.5 ounces (128 g) without the frame mount. This pump has a flex hose with a threaded Presta connection on one end and a threaded Schrader connection on the other. The flex hose is stored inside the pump when not in use and the entire unit attaches easily to your bike frame with the included pump mount.
This pump is 9.2 inches long and about as big around as a quarter. The pump is rated for a maximum pressure of 90 psi, but if you ride a Fat Bike, or even most mountain bikes, you are never going to need pressures near that high.
The Lezyne Alloy Drive pump retails for $45 and is available in four colors (Black, Blue, Red and Yellow). You can purchase this pump directly from the Lezyne website or from your local bike shop. If all else fails you can also find it on Amazon.com.
