What is the difference between HV and HP?
The main difference between HP (High Pressure) and HV (High Volume) hand pumps is the barrel diameter. The HP hand pumps have a smaller barrel diameter that pushes less air volume than the HV pumps, but allows you to achieve a higher pressure. Typically you want a HP hand pump for "high pressure" tires. This mostly means skinny tires, but some people have big wide tires that need high pressure. As you probably guessed, HV pumps work better on "high volume" tires that require lower pressures (mostly mountain bikes). HP pumps will inflate large tires and vice versa: HV pumps will inflate tires to high pressure. The reason there are two is that HP pumps will require a lot more strokes (and time) to inflate high volume tires and HV pumps will require a lot more strength to inflate tires to high pressure.
Which hand pump should I buy?
That's a good question. It's difficult to answer for a number of reasons. My question to you would be "what type of bike will you be using this on?" To have one-on-one help picking out the right pump, you should go to your local Lezyne dealer. Since you are already on the internet, I would suggest first checking out the Lezyne Buyer's Guide.
Can my HV pump work on my road bike?
A high volume pump will "work" on your road bike. The issue with using a high volume pump on a high pressure tire is that most people aren't strong enough to get the tire up to a proper riding pressure. In a pinch most people could probably get it up to a high enough pressure to carefully ride home, but be warned, riding on an improperly inflated tire is not safe and could result in something terrible happening to the bike or the rider. I have heard of someone using a Micro Floor Drive HV to pump air into a suspension fork on the trail. It isn't designed for that, but I guess it worked well enough to ride home.
Can my HP pump work on my mountain bike?
A high pressure pump will certainly work on your mountain bike, provided that the pump in question is compatible with the valves used on your mountain bike. Most mountain bikes have high volume tires. The main reason we do not recommend the use of high pressure pumps on high volume tires is that it will take longer to get the tires up to riding pressure.
Can the pen gauge work on the small Lezyne pumps?
The Pen Gauge can work on Small Lezyne pumps, however it will not store inside of the handle as the normal Flex Hoses do.
Why doesn't the pen gauge come with an ABS chuck?
Unfortunately there currently isn't a way to incorporate an ABS chuck onto the pen gauge in a way that will still fit inside a hand pump. The ABS chuck is compatible with the Pen Gauge, you just can't hide it in the pump.
How many strokes does it take to inflate a tire?
I won't pretend to know how many licks it takes to get to the tootsie roll center of a tootsie roll pop. I honestly don't know. Most bike shops should let you try out a pump before you buy it. It's a silly measurement anyway since the fewer pump strokes required to inflate your tires, the more difficult each stroke will be. For various reasons, it is impossible for me to tell you how many pump strokes it will take to inflate your tires. One of those reasons is the huge amount of error I will have. For your amusement I will list a few of the others: Tire size, Tire volume, Rim width, Inner tube thickness, Desired pressure, Pump size, Pumping technique, Pumping speed, The weather, Your current elevation
Can the road drive really reach a max pressure of 160PSI?
The pump will go as high as it's rated, you just have to be strong enough to get it there. If you absolutely need your tire to be at 160psi (11 bar) I suggest using a CNC Floor Drive. Remember, hand pumps are primarily for getting you enough pressure to get you home.
What is the actual rated pressure for your pumps?
The short answer is no. The claimed pressure is the same as the "actual" pressure. The long answer is that it depends. The rated pressure is what the pump is known to be capable of. The actual pressure is what the user is capable of. If you weigh 90 pounds, you probably won't be able to use a HAND PUMP to get a tire up to 90 psi. I just don't think you would have the strength. Lezyne pumps will get you up to riding pressure. What that pressure is depends more on how strong you are.
What is the difference between the road drive and pressure drive pumps?
Barrel Diameter: The main difference between the Road Drive and Pressure Drive hand pumps is the diameter of the barrels. The Road Drive barrel has a slightly smaller diameter which makes getting up to higher pressures a bit easier on the arms. Flex Hose: It should also be noted that the Flex Hose that comes with the Road Drive is only compatible with Presta valves while the Pressure Drive is compatible with both Presta and Schrader type valves. The newer ABS Flex Hose that comes with the Road drive has both threaded and a slip-fit Presta valve connections. Mounting Bracket: While both pumps come with brackets for mounting to bottle cage bolts, only the Road Drive comes with an aluminum one. The pump bracket for the Road Drive is only designed to hold the barrel of the pump, so the pump also comes with a barrel sleeve to keep the pump closed when not in use. The mount for the Pressure Drive is made from Composite Matrix and is designed to hold the handle and the barrel of the pump. Sizing: The Road Drive is available in Medium and Large sizes while the Pressure Drive is available in Small and Medium sizes.Colors: Both the Road Drive and the Pressure Drive are made out of aluminum, however they are available in different colors. The Road Drive is available in Black and Silver anodize colors and in a White powder coat finish. The Pressure Drive is available in Black, Red, Gold, and Blue (Blue unavailable in U.S.) anodize colors.
What is the difference between the ABS flex hose and the ABS speed flex hose?
The ABS Flex Hose has a threaded connection on both sides. One side of it is designed for Presta valves and the other side is developed for Shrader valves. The ABS Speed Flex hose comes on the Road Drive and Carbon Road Drive hand pumps only and is designed for use with Presta valves only. One side of the hose is a NON-THREADED connection for speed and ease of inflation, while the other side is a threaded Presta connection.
Will the ABS flex hose work with my older Lezyne pump?
Our new ABS Flex Hose, though it does come with the new ABS feature, threads in and out of hand pumps the exact same way that it used to. No change in size or shape has been made to our hoses. The short answer is: YES. P.S. ABS Flex Hoses are available separately for purchase if you're looking to upgrade your older hand pump.
Do your hand pumps work on valve extenders?
Lezyne hand pumps utilize a threaded connection in which the Flex Hose threads directly onto the valve. If your valve extenders have threaded tips which accept a standard plastic dust cap, then your Lezyne pump will work with your extenders. If your valve extenders are smooth and do not have a threaded tip, there are 2 options which you can choose from: Buy Lezyne Valve Extenders which have threaded tips compatible with Lezyne's threaded Flex Hose. Upgrade your pump with Lezyne's ABS Speed Flex Hose which has both a Presta threaded connection and a Presta Slip-Fit connection. The ABS Speed Flex Hose comes standard on both the Carbon Road Drive and Road Drive hand pumps, and may be purchased as an upgrade separately.
What is the difference between the hand pumps?
The major distinguisher between every hand pump in our line is materials used. To set a dramatic example, I will explain the major difference between our Carbon Road Drive (100 dollar) and our Classic Drive HV light (22 dollar). Our Carbon Road Drive is made of: Full carbon barrel (for weight) CNC endcaps and internal parts (for strength, weight, and durability) Our Classic HV Light is made of: Aluminum shaft and piston (durability), Composite matrix handle, endcaps, and head. Some things to consider when purchasing a hand pump are: What bike will you be using this on (road or mountain bike)? How often will you be riding/using your pump? What types of conditions will you be riding in? The best thing that you can do in looking for a pump is visit our Buyer's Guide
What is the difference between the two shock pumps?
Our Shock Drive is designed for those mountain bike riders who like to take a shock pump with them on their rides in order to fine tune and adjust their suspension on the fly. Our Shop Shock Drive is designed to be a "shop" tool. Although it will not be traveling very much and weight isn't an issue, it is built to outlast the everlasting abuse of bike mechanics on their tools. The oil-filled gauge ensures accuracy of pressure and gauge protection too.
Why does the shop shock drive have an oil filled gauge?
The Shop Shock Drive was designed to endure the rigors of everyday life in a bike shop. The gauge is filled with oil to protect it from damage while moving around in your tool box. Besides, it looks cool!
What is your lightest hand pump?
Our lightest pump is the Carbon Pressure Drive, and it weighs in at 62g. The next closest pump is the Carbon Road Drive 2 at 89g.
What is your smallest hand pump?
Lezyne's smallest hand pumps capable of inflating tires come in the Small size. These pumps measure about 7.5in/19cm in length. Although the Shock Drive is the smallest pump that Lezyne makes, it is not capable of inflating a tire. It is designed to only inflate shocks. Lezyne offers both HP and HV pumps in the Small size. High-Volume Pumps (mountain): Carbon Drive S, Alloy Drive S, Tech Drive HV S, HV Drive S. High-Pressure Pumps (road): Pressure Carbon Drive S, Pressure Drive S, Tech Drive HP S, HP Drive S.
Do you make a frame pump?
While we often receive requests to make an older, more traditional style "frame pump", it is extremely difficult to make a pump that meets Lezyne quality and performance standards while at the same time fits the wide variety of complex frame geometries and tube shapes of modern bike frames. Therefore, we attach our pumps with a mount that uses water bottle cage bolts since almost all frames accept water bottle cages.
Can I rebuild and service my hand pump?
Our Hand Pumps are built using very few parts, so rebuilding them is quite simple and easy, though can certainly be messed up. If you are experienced with rebuilding things or mechanically inclined, feel free to rebuild our pumps. We do sell rebuild kits and spare parts for pumps if they are necessary. If you want it rebuilt for you, send it in as a warranty.
Why do Lezyne pumps thread onto a valve?
Lezyne designed almost all of our pumps with a threaded connection because it is the most effective way to ensure that all of the air that you pump actually goes into the tire, that you don't break valves off of tubes with "smart heads", and that pumping tires up is no longer a "hassle" or "hard to do".
With the speed flex hose, what does "reversible presta only" mean?
"Reversible Presta-only" means that BOTH sides of the hose are Presta-only compatible. Both sides of the hose are ABS (Air Bleed System) equipped, however, the difference between sides is that one side is a Slip-Fit system that slides straight onto the valve, while the other side is a Thread-On connection.
