我們不用ｌｕｘ去測量.

大多數的廠家使用ｌｕｘ來做測量。但是這個方法是不準確的,  因為這跟你將測量儀器放置在離光源多遠距離有關, 只有使用積分球才能真正測量出最可信及可靠亮度。

LED科技目前很先進,一般的LED能有靠近無限的壽命。也可能比你的壽命更長。

LEZYNE使用一套方法叫 integrating sphere(積分球)來測定流明度, 這套方法是測量光的實際輸出量。

簡單來說　不管光束模式是甚麼　流明是燈發出來的總光量。使用integrating sphere是最真實及準確的方法測量光的實際輸出量因為考慮到各方面的因素。

在ＬＥＺＹＮＥ，我們只用最好的ＬＥＤ科技。　我們研製每一個燈都會確認最適合的LED。因此我們目前沒有集中在一個ＬＥＤ廠家。　因為這樣我們可以在市場裡開發最好的燈同時沒有和任何人或廠商有關聯或限制。　最簡單來說　我們用的都是最好的。

 流明是光通量的標準單位, 總而言之就是測量每一秒從光源所放射出來的實際亮度, 有點複雜嗎? 簡單來說流明數越高代表亮度越亮。

就現況而言, 流明數在仿間有三種不同解讀方式; 第一種(最多人用的)就是由LED製造商根據光源輸出理論所提供的數據(他們說有"X"的亮度, 產品就會有"X"的亮度),  第二種方式是測量Lux的數值, 比較容易操控於某一燈杯的角度, 這種量測法並不準確, 因為可以人為操控測量角度且距離也會影響測量值, 第三種方式是以積分球方式測量, 實際量測光源輸出的亮度, LEZYNE目前選擇第三種方式, 不相信廠商所宣稱或人為操作, 只讓數字說話。

因為這三種測量單位在自行車燈產業上都有人使用因此我們必須釐清有何不同。
- Lux是根據燈杯內某一個局部位置去測量而得數值, Candela是測量光亮單位的一種, 主要是測量單一燭光在任何距離所釋放出來的亮度, Candela不會因距離遠近而影響數值, 但是lux會被影響。
- Lumens 仍然是最好的測量方式, 因為它可以量測所有光源且不被距離影響可以說兼具各方優點。

因為我們使用積分球來測量亮度因此我們可以說相當真實掌握了光源輸出的數值, 然而這並不代表光束(形)就不重要了, 我們並非只在意亮度, 同時也在意光束的廣度及亮點是否過度集中的問題, 我們稱之為最大廣度燈杯設計。

我們使用積分球來測量燈, 在非常短時間內, 間燈放入巨大球體內, 內部有反光體, 將所有數值集合起來就可以獲得測量數值, 積分球可以想成一擴散器, 將光源收集起來不受距離限制。

這是唯一的方法去得知真實結果, 流明輸出值得測量是在正常溫度下開燈並測量燈光離開鏡面那一刻的數值。

The Flip Chuck can be used on both Presta and Shrader valved and with ABS. The Flip Chuck is also a THREADED connection, so it threads onto the Presta and Shrader valve stems. The Speed Chuck can be used on Presta valves only and does not THREAD ON to the valve stem, as the Flip Chuck does.

Quite simply, the difference between the Speed Chuck and the Slip Chuck is material. Our Speed Chuck is made of a Composite Matrix plastic and comes with all of our floor pumps. The Slip Chuck is all CNC-Machined aluminum and is what might be called an "upgrade" for those people desiring the perfect look with their floor pump or the long-lasting durability of aluminum.

We do not sell extra O-rings for the Speed or Slip Chuck because upon buying one of our pumps, you receive 6 extra O-rings. These should last you as long as you are riding your bikes, no matter how often you're using your pumps. Should you run into any issues, please contact Lezyne and they will be more than happy to help.

Lezyne designed all of their pumps with a "thread-on" connection in order to ensure a proper seal between our Flex-Hose and the valve stem itself. This is done to ensure accurate pressure readings and proper tire inflation. We also designed this for ease-of-use. When out on the road or on the trail, didn't want you to worry about the head connection failing/slipping. We all know that this can be rather frustrating and we decided to save you the hassle from the get-go.

Our pumps can be serviced and rebuilt, however, attempting to do so on your own terms may void the warranty if any issues should further arise. It is recommended that you simply send your pump back to us if you're having issues with it. It will be fixed well and returned very quickly. However, if you're very mechanically inclined and up to the challenge, we do sell pump rebuild kits and you're welcome to have a go at it. Lastly, our pumps are build so well that we RARELY have to rebuild a pump. If you wear out one of our pumps, my hats off to you.

"ABS" stands for "Air Bleed System". This is a system that Lezyne developed last year into their product line. We had heard some feedback that our Thread-On connection sometimes removed the valve stems from the tubes. In order to fight this, we developed "ABS", which is a feature designed to release all of the air pressure out of the pump's system in order to make removal of the pump from the tube easier.

All of our new ABS Flip Chucks thread into the exact same style of connection as the older Thread Chucks. This means that if you buy an ABS Flip Chuck, installing it onto your "older" pump will be a piece of cake.

A broken gauge can be fixed on your floor pump. After obtaining all of the necessary parts to fix the gauge, you can go to Lezyne.dozuki.com and find the proper Guide to help you through the steps necessary to replace your gauge. It is not an extremely complicated process, but if you do not feel like doing this on your own, in most cases, it will be covered by warranty.

Lezyne's floor pumps do work with valve extenders. This also goes for all of our hand pumps. So whichever pump you might be running, all of our pumps will work with any valve extender that you want to run with.

You can purchase and replace the hose on your floor pump. It is a relatively easy fix that is recommended if your hose is what might be called "beyond its years". Because the hose contains up to 220psi, having a good hose installed is crucial.

Some users have experienced issues with valve cores unthreading upon pump removal. There are a few reasons why this might happen and there is more than one solution.

Lezyne has a few solutions for you.

Many inner tube manufacturers do not sufficiently tighten valve cores upon assembly. First check that your valve cores are properly tightened.
Do not overtighten the pump onto the valve. This could result in the pump being more strongly connected to the valve core than the valve core is to the rest of the valve.
Lezyne has made the Slip Chuck for a while. It has a slip-fit connection which should not interfere with valve cores.
All of the newer pumps are equipped with ABS (Air Bleed System). For Presta valve users, depressing this button releases all of the air pressure in the hose, but not in the tire. Releasing all the hose pressure reduces the friction in the system for easy pump removal.
All of the new ABS equipped floor pumps also come standard with the new Speed Chuck which is similar to the Slip Chuck, except that it attaches to the Flip Thread Chuck instead of directly to the pump hose.

In conjunction with our Floor Pumps, the Speed Chuck utilizes a 90 degree bend in its design so that it can fit in disc wheels.

The Gold ABS Chuck is designed for our HP Floor Drives while the Red ABS Flip Chuck, being designed in higher volume applications, needed to use different parts to use the higher volume air flow.

Your Dirt Floor Drive will inflate your road bike tires/tubes, however, not only will the Gauge NOT go past a 70 PSI reading, doing so might break your gauge.

Your Dirt Floor Drive will inflate your road bike tires/tubes, however, not only will the Gauge NOT go past a 70 PSI reading, doing so might break your gauge.

Lezyne offers both an HP and HV version of every pump for both ROAD and MOUNTAIN BIKE applications. "HP" stands for "High Pressure". Road bike tires are thin, low volume, and require higher pressures to run well (anywhere between 90 and 160 PSI). Our HP pumps are designed to make it easier to pump up road bike tires to those pressures by using smaller pump barrels. "HV" stands for "High Volume". Most mountain bike tires these days are run between 2.0" and 3.0" wide. Requiring so much air to fill up these tires, we developed our HV pumps with bigger pump barrels to push more air into the tires, making inflation of mountain bike tires faster and easier.

If you had to choose one pump, I would suggest going with one from the high pressure lineup. You may not be able to read lower pressures as accurately as with a high volume pump, but it can inflate both tire types up to proper riding pressure.

Without going into detail, most of the differences are in materials and features. Generally the higher-end pumps are made with more aluminum. The gauges on the higher-end pumps typically go up to higher pressures as well. Aesthetics is the other difference.

We do not have any adaptors for air compressors. Our Dirt Floor Drive are so effective in High Volume applications that they eliminate the need for air compressors (to seat tubeless tires) completely.

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.

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.

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.

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.

The Pen Gauge can work on Small Lezyne pumps, however it will not store inside of the handle as the normal Flex Hoses do.

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.

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

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.

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.

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.

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.

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.

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.

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 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.

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!

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.

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

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.

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.

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".

"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.

CO2 inflators, because they work with such high pressure canisters, are most efficient when the head is actually threaded onto the valve. Often, with non-threaded connection, some of the CO2 that is meant for the tire ends up leaking out past the valve itself.

Our ABS system cannot withstand the extremely high pressure contained within our CO2 canisters and CO2 Flex Hoses.

You can use the CO2 Flex Hose with other Lezyne hand pumps.

"CFH" stands for "CO2 Flex Hose", meaning that all of our CFH applications have a CO2 Flex Hose in them. The designation of "Road", "Pressure", or "Alloy" denotes volume, where Road Drive CFH is meant for Road applications, Pressure Drive CFH can be used on both Road and Mountain bikes, and Alloy Drive CFH is meant specifically for Mountain bikes.

The designation of "Road", "Pressure", or "Alloy" denotes volume, where Road Drive CFH is meant for Road applications, Pressure Drive CFH can be used on both Road and Mountain bikes, and Alloy Drive CFH is meant specifically for Mountain bikes

Our ABS system cannot withstand the extremely high pressure contained within our CO2 canisters and CO2 Flex Hoses.

You can use either 16g or 25g cartridges in any CFH application. It simply depends on what tires that you plan on inflating with them (road vs. mountain). 25g cartridges fill higher volume tires and 16g cartridges are meant for lower volume applications.

If you have a Lezyne inflator/head, you MUST use a Lezyne cartridge with it because our heads require THREADED applications/canisters. We designed our systems this way with safety in mind as well as efficiency.

The short answer is "No."

The Alloy Drive CO2 has a canister body in order to safely store your cartridge when it's not being used and also to help keep your hands warm while inflating tires with your CO2.

The Speed Flex Hose DOES NOT work with disc wheels. This hose does not have a 90 degree bend in it that would allow it to work on disc/full race wheels. Our Micro Floor Drive HP/HPG with a Speed or Slip Chuck on it would solve the problem though…

In designing cages, we wanted to design something for everybody. Some cyclists prefer mounting there pump straight onto their bike next to their water bottles….it's quick, accessible, and integrated into your bike. Others prefer running with their pumps in their jersey pockets or pack and instead want a water bottle cage that serves as a water bottle cage and nothing else.

Some cyclists prefer mounting there pump straight onto their bike next to their water bottles….it's quick, accessible, and integrated into your bike. Others prefer running with their pumps in their jersey pockets or pack and instead want a water bottle cage that serves as a water bottle cage and nothing else.

We designed our cages to fit a large variety of bottles. We cannot guarantee that every bottle will fit PERFECTLY, but every bottle will certainly fit into our bottle cages and will work well. Because there are a number of different bottle shapes and sizes, we just do our best to design for a happy middle ground on all of them.

For 2013, Lezyne introduced the Side Load variety of cages, which includes both Carbon and Nylon versions (in both Left and Right loading options). The good thing about this cage is that it's designed specifically to work on extremely small, modern, compact geometry framesets.

Any water bottle in ANY bottle cage will scratch over time and with excessive use. Anybody who says otherwise is lying to you.

We just introduced a Side Load Cage for 2013 in both Carbon and non-Carbon varieties.

The only difference between the Stainless and CRV tools is the side plates and hardware material. The stainless tool uses stainless steel tool bits and side plates, while the CRV tool uses Chrome Vanadium tools and side plates.

The SV tools use stainless tool bits and side plates, while the V tools use Chrom Vanadium tool bits and side plates.

Our smallest and lightest multi-tool is the Carbon 4. The tool bits are machined Titanium and extremely small, yet rigid and strong.

The best resource to help a road cyclist decide on a tool is our Buyer's Guide at www.lezyne.com/buyers-guide. However, the most well-equipped, versatile, and long-lasting tool that I can recommend is our SV10 tool.

L-bend allens make some awkward and hard-to-get-to allen bolts easier to reach and work on. They also give you much more torque if necessary.

Lezyne does not make a cassette tool for Campagnolo drivetrain parts. The only Campy-compatible tool that we make is our 11 Speed Campagnolo chainbreaker.

Our Chain tools cannot be used on 11 speed cassettes.

With enough elbow grease and determination, you can make almost any number of things work together. My suggestion is: go for it. However, don't point any fingers my way when we say that it voided the warranty.

Our CNC Rod was designed specifically to be used in conjunction with our 2-Way tools. No other manufacturers tools will work with our CNC Rod.

The bits on our 3-Way Tools are designed and sized sepcifically for each individual tool bit, so the answer is "No."

Our glueless patches are simply pressure sensitive patches that you peel and place on the tube where a hole is present. They are quick and easy fixes for on the fly repairs. Our Classic Kit still uses glue to adhere the patches to the tube, creating a more permanent bond with the tube. In short though, it is simply a matter of preference and both types of patches will solve your problems.

The Lever Kit is what we call weather-resistant. It will without a doubt keep water out of your tire repair goodies.

Our glueless patches work very well even on high pressure applications, such as 23C road tires.

Lezyne tire boots will patch a tubeless tire in an emergency. It will hold long enough to get you off the mountain or road, but should be taken out and the whole tire should immediately be replaced.

The Alloy Kit comes in a polished and machined case, while the Metal Kit comes in a bead blasted case with color options.

You can use your Saber Lever to remove pedals, however, it should be done with caution because slipping your hand while attempting to remove pedals can hurt really bad.

It is safe, but NOT recommended. Metal should NEVER be used on carbon wheels. We developed the Power and Matrix Levers for carbon wheels and applications where scratching needs to be avoided.

Power Levers were designed to give you extra torque on wire beaded tires. They were also designed with integrated spoke hooks that allow you to hook the lever onto a spoke, freeing up both of your hands completely. The Matrix Levers are designed strictly as a tire removal tool with no extras.
