DIY bike bottle cage

Choosing the right bike flask

  • Flask volume. On sale you can find containers with a volume of 0.5 to 1 liter. For cyclists who often take long cycling trips, experts recommend purchasing large bottles. at least a liter, since a lot of liquid is consumed on the road: standard 0.75 liters per 50 km of travel is usually too little.
  • Valve and cover arrangement. Care should be taken that the valve is strong enough not to open spontaneously without making it difficult to drink while driving.
  • The material from which the product is made. A number of requirements are imposed on the material. from strength (so that the bottle does not break if accidentally dropped) to the quality of plastic (otherwise the water will absorb the unpleasant chemical smell of poor-quality material). Food-grade plastic and aluminum are known as standard materials for the manufacture of bicycle flasks. Of course, aluminum thermal flasks keep the coolness much better, or, conversely, the heat of the liquid placed in them.

FACT! Recent developments offer flasks with a ceramic coating: such a material not only allows you to maintain the taste of the liquid, but also maintains the temperature for a long time.

Bottle cage: what it is?

A high-quality flask mount should be as reliable and durable as possible in order not only to attach to the bike, but also to hold the flask as well as possible. A flask that falls out during movement is dangerous not only by the loss of a bicycle item, but also by creating an emergency on the road. Therefore, special attention of buyers is used by those mechanisms that can be adjusted depending on how much the bottle fits in them: this allows you to take a small container for a short walk, and on a long journey. a massive flask with a large volume.

According to the material from which the underflags are made, there are:

FACT! Carbon fiber liner weighs no more than 20 grams, which is extremely important for professional cycling.

Each cyclist will find it convenient to attach the bottle cage: on the handlebars, on the frame or under the saddle. The standard mechanism, as a rule, can be attached to any of the selected places, but it is important to consider the height of the structure and whether it will interfere with the ride when a rather large bike flask takes up space.

The standard place for attaching the flask is the frame, and most often experienced athletes install two holders: on the lower and seat tube of the frame. This allows you to transport two flasks at once and not be distracted during a long journey to get more water. If there is no need to increase the amount of water, then it is enough to fix the holder on the lower tube of the frame. such a mount is considered standard and convenient for the vast majority of users.

You can attach the bottle cage to the steering wheel, this arrangement has a lot of advantages: there is no need to bend over the bottle while driving, but this creates an additional load on the hands.

What to carry life-giving moisture?

At first glance, especially for an unprepared cyclist or a stranger, it may seem that a bicycle flask is not very important, if not an overkill. But on examination it turns out that there is nothing to do on a long bike ride without a high-quality bike bottle. The common man retorts: they say, a regular bottle of suitable volume fits perfectly into the holder for a flask on a bicycle. Isn’t that enough? Of course not. The bicycle flask has several clear advantages over plastic containers:

bike, bottle, cage
  • The bottle cap cannot be opened on the go, and the bicycle bottle cap can be dealt with, so there is no need to abandon the handlebars or stop altogether to drink water.
  • The design of any flask, even a fairly budget model, differs significantly from a banal drinking bottle. It is much more rigidly held in a special holder, which makes it almost impossible for the container to drop out during off-road driving.
  • Most bicycle flasks are made on the principle of a thermos, that is, they keep the water cold for a long time.

Every cyclist who understands will say with confidence that covering a long distance without drinking is not only impossible, but also dangerous to health. Carrying water the old-fashioned way in a plastic bottle by placing it in a shoulder backpack is a thing of the past. Therefore, a bottle cage and a high-quality bicycle bottle are as necessary accessories for a bicycle as a bicycle computer, bicycle lock, a bicycle pump or a bicycle bag.

Bicycle bottle: proper care

No matter how expensive and branded the purchased bicycle flask is, without proper care it will quickly lose not only its attractive appearance, but also its basic properties. If the bottle is carrying only water, then a simple rinse after each use will be sufficient. But sometimes a cyclist, setting off on a journey, takes with him more serious liquids: broth, compote, milk. After such contents, the bottle must be thoroughly washed with the use of special detergents and a brush.

In addition to the cavity, the flask cap also requires careful maintenance: being in contact with road dust, it can clog up rather quickly. The occurrence of such blockages sometimes leads to jamming and can interfere with the trip.

TIP! Clean the cap of your bike flask from plaque and dirt several times during the cycling season: this will not only prolong the life of the flask, but also improve its performance.

How to make a bottle cage with your own hands?

For this, a sincere desire and a little skill in working with such materials are enough. As a rule, for the independent manufacture of holders for flasks, thick aluminum wire, clamps and a couple of bolts are used: and if in order to bend it to the required shape, almost no one has any difficulties, then it will not be easy to organize competent fastening to the frame for the created structure.

Location of bottle cages

The most common locations for bottle cages are:

Frame. This is the most common and convenient option. Almost any modern bicycle has special threaded holes with a diameter of 5 millimeters, which are located on the bottom or seat tube of the frame and serve to attach a pump or bottle holder. Typically 64 millimeters apart, they are standard sizes and fit any type of bottle cage.

The handlebars are another common place for attaching a canteen. The fluid container is attached directly to the handlebars with clamps. In this case, you don’t even need to bend over to get the bottle and get drunk. However, it already contains many different devices: shifters for shifting gears, brake levers, rear-view mirrors, a bicycle computer, and much more. The flask will distract and also add weight to the front of the bike.

Another way is to install the holder with ties to take out. Another interesting, but rather rare option is the installation of a special plate with holes for the stem cover. Hole diameters and spacing are usually standard, allowing the most common types of bottle cages to be installed, which are usually mounted on the frame.

Upper frame tube. If the hike is to be long, then this place, as a rule, is located flasks with an additional supply of water. They are usually placed in a case or bag made of fabric or leather and are attached with straps. It is also possible to install a holder made of plastic or metal wire. The top tube is still not very suitable for transporting bottles of liquid, especially of non-standard sizes, as with active pedaling, they can touch your knees and create inconvenience. In addition, cables are usually laid along it.

Seatpost. It also hosts flask holders quite often, as it is easily accessible while riding. The disadvantages of this arrangement are the absence of mounting holes, as well as the impossibility of visual control. If the flask falls out on the move, then you most likely will not notice it, and as a result, it will be lost.

Saddle. The saddle frame can also be used to install the holder. Most often, holders made of metal wire with special clips or screws are used, which are attached quickly and easily and allow you to transport several flasks at once. The main disadvantage is the same as in the previous method. difficult control.

The trunk. If your bike is equipped with this device, you can also place a supply of water on it by installing special holders on it. In this case, you can transport a fairly large number of bottles, placing them horizontally or vertically. Since the trunk is located at the back and when driving falls out of sight, this option has the same drawback as the previous two.

Front fork. In some cases, the front fork of the bike is used to transport water. The holder attaches directly to the pants, and you can use both sides at once. right and left. This method is good in that there are no special restrictions on the size of the container with the liquid and allows you to attach rather large bottles. The fork is always in front of your eyes, which is another advantage, since the loss of the flask will not go unnoticed.

Bike helmet. This is a rather curious way of transporting flasks, in which the holder is located directly on the protective helmet. Water weighs quite a lot, and an additional pound or more creates an unnecessary load on the neck, so this option is not widely used.

As you can see, there are quite a few places that allow you to fix a bicycle bottle cage, and everyone can choose the design to their liking, guided by such criteria as ease of access, convenience and reliability of fixing the vessel while riding, as well as personal preferences.

Types of bottle cages

A bicycle water holder is one of the most needed accessories. The correct choice of this device determines the reliability of the flask fixation and the comfort when riding the bike. The sudden loss of a vessel distracts attention at the most inopportune moment. As a result, you or your friends riding behind can fall and get injured, and constant stops and searches for the lost bottle can ruin the pleasure of any bike ride.

There are many different types and designs of bicycle bottle cages. They differ from each other in location, material of manufacture and method of fastening. Most often, they represent a bottle holder and fasteners that hold it. The retainer is adjustable and non-adjustable, and the holder itself can be mounted on a wide variety of parts of the bike.

Bicycle bottle holders, their types and installation

As we have already found out, a lack of water not only causes discomfort, but can also cause serious health problems. You can use a backpack or bag to carry fluids while cycling, but if you are racing, then this method is unacceptable. In addition, in the sun the backpack heats up the back a lot. Traveling as part of a group will also not allow this option, because all participants in the race will have to stop every time someone wants to quench their thirst. Therefore, it is most convenient to place the container with liquid on the bike itself.

The supply of water can be stored both in a regular plastic or glass bottle, and in a special bicycle flask designed for this purpose. The second option is preferable, since such vessels have a valve that allows them to be opened with one hand. In any case, to fix the bottle, you need to install a special mount, which makes it possible to easily and quickly get water and get drunk.

Dehydration and its effect on the body

From the school course on anatomy, everyone knows that the human body is about 70% water. With a lack of fluid in the body, its work is disrupted at the cellular level. Dehydration has a negative effect on the functioning of the joints, and since when cycling, the main load falls on the knees and back, they are the first to suffer.

The cartilaginous tissue, which is located at the ends of the bones, protects them from direct contact with each other. It contains a large amount of water and allows the cartilage to slide over each other’s surface. A decrease in the amount of intra-articular fluid during dehydration of the body makes the cartilage less slippery and causes pain.

The environment in which cartilage functions is alkaline with normal moisture content in the body. With a lack of water, it oxidizes, destroying joint tissue and increasing friction. The joints become swollen and lose their mobility. As a result, bone growths appear. Dehydration of the body leads to very sad consequences and causes osteoarthritis.

Dehydration also has an extremely negative effect on the functioning of the spine, provoking the erasure of intervertebral discs, disrupting their structure, making them brittle and fragile. This entails the emergence of protrusions and intervertebral hernias, giving rise to severe pain. It is dehydration that is responsible for the onset of torcalgia and lumbodynia. Therefore, diseases of the musculoskeletal system are occupational ailments among sportsmen-cyclists.

Intervertebral hernia

Another danger for cycling enthusiasts is heatstroke. Even with a leisurely movement on the bike, it seems that a light breeze is blowing around you, creating a deceptive feeling of freshness. Even if the temperature outside is not too high, the risk of overheating in the sun during long cycling trips is very high.

Dizziness, nausea, vomiting, feeling of weakness, rapid breathing and palpitations. this is not a complete list of symptoms inherent in heatstroke. In especially severe cases, loss of consciousness and even death is possible. Therefore, during a bike ride in the heat, it is very important to drink a lot of fluid, which is secreted with sweat and serves for proper thermoregulation of the body. Lack of water leads to overheating, the consequences of which can be extremely severe.

Holder materials

The design of bicycle bottle cages is quite diverse both in design and appearance, as well as in color and material that is used in their production. In most cases, the following materials are used for the manufacture of such fasteners:

  • Aluminum. The bottle cages made of this metal have a low weight, high strength, but with constant use they scratch the bottle. In addition, the fixing reliability decreases over time.
  • Plastic holders are among the most popular, as the bottles fit very tightly in them, and they can be removed and put back quickly and easily.
  • Stainless steel is a fairly reliable and inexpensive material, but with intensive riding on rough terrain, structural destruction often occurs in spot welding.
  • Titanium alloy. Titanium holders are strong and lightweight, but quite expensive.
  • Carbon. CFRP is the lightest material used in bicycle bottle cages, but is very expensive and is mostly used in professional sports.
  • Cloth and leather are commonly used for holders that attach in places that do not have seating holes. As a rule, they have an individual design and serve as a beautiful and stylish accessory.

The design of the bottle cage and the material from which it is made largely depend on its location, as well as the expected operating conditions. For simple rides over short distances, a regular plastic or aluminum bottle holder is suitable for a small size. Those who are going to participate in races or long trips should turn their attention to titanium or carbon.

Methods for attaching bottle cages

In most cases, installing the bottle cage is straightforward. To attach it to your bike, simply align the holes in the base of the holder with the corresponding holes on the tube and fix it with screws. Difficulties arise in the absence of special seats on the frame or when placing the bottle clamp in a non-standard place.

There are several ways to solve these problems. The easiest way out of the situation is to fix the holder using special clamps, which are usually included in the product delivery set. Some cyclists use straps or plastic ties, but this is highly discouraged as they may not provide sufficient support.

The next option is to drill holes in the frame and fix the bottle cage with self-tapping screws. Doing this is also highly discouraged, because such actions can lead to weakening of the frame structure and its destruction.

You can fix the device for transporting water bottles with glue, but the reliability of such an installation is due to the properties of this glue itself. Modern formulations may well provide sufficient fixation strength, but it all depends on the magnitude of the loads that the holder experiences when driving.


In some cases, the bottle cage is simply welded to the bike frame or other location. This method is most suitable for frames made of alloy steel. It is still better to weld not the holder itself, but a separate plate with projections and holes, to which it will be screwed with screws in the same way as in the very first standard version.

Leather or fabric straps with tongue or slotted buckles, or Velcro straps can also be used as fasteners, especially when the holder itself is made of these materials. This mount is quite reliable and easy to install and remove.

Some companies offer a rather unusual bottle holder. with magnets. The kit includes a special bottle and a plate that fits into a regular slot on the frame. The surface of the bottle has a groove in the shape of this plate and a strong magnet that is attracted to the plate. The manufacturer claims that in the course of the tests carried out, this method of installing the flask showed excellent results. The cost of such a device is approximately 50.
