I want to know more about bicycle hubs

A hub is the part that connects the transmission and the wheel.

The front and rear hubs are not the same, and the rear hubs are connected to the drive.

The disc brake hub should be connected to the disc, with a brake seat, and the V brake does not.

The design of each house is different, and the big ones have the distinction between balls and bearings, and the difference between flying and spinning.

The number of holes is to match the ring.

Different flywheel stages may use different hubs, and some of the same structure can be adapted to different flywheels by replacing the tower base.

Bicycle hubs, also known as "hubs and simple burning barrels", are the barrels that connect the spokes on the outside of the shaft, generally called the shaft skin. According to the different arrangement methods of the number of pieces, there are usually compilations of manga 3 and mandy 5. There are 2 types of hubs: iron hubs and aluminum hubs.

The wheel hub system of a bicycle includes shafts, bearings, shaft hubs, etc. Hubs include iron hubs and aluminum hubs. Iron hubs are bicycle hubs that are usually ridden at homeAluminum hubs are usually high-grade hubs used as hubs for mountain bikes, show bikes, road bikes, and other kinds of hubs.

There are 32 H and 36 H2 types of rims, which are the number of spokes. Depending on the number of spokes, there are usually three or five styles of spokes.

Composition of the wheel**:

On the road of DIY mountain bike, the DIY of wheels is the most difficult part, which tests a person's experience, a person's patience and adaptability. I believe that most of my friends gave up the DIY of the whole vehicle because of the step of knitting circles, in fact, I was the same at the beginning, but I did it and did it. Because it started, there is no way back, because it can only move forward, so all difficulties are temporary, as long as you think, you will take tricks.

Volume 1: Hubs.

All modern high-quality hubs are made of aluminum. The best hub rims are usually forged and only forged hub rims can be used on radially spoked front wheels. It is advisable to avoid those CNC hubs as much as possible, as their rims are usually not as durable as forged hubs.

The length of the hub should correspond to the opening of the frame fork, otherwise, it cannot be installed. There are two common types of hubs:

Rotary hub: Rotary hub is often used for bicycles below 7 speeds, rotary type, refers to the installation form of the flywheel is locked on the hub through threads, the biggest disadvantage of this hub is that it is not easy to disassemble after a long period of use.

Cassette hub: Cassette hub is mostly used for bicycles above 8 speeds, cassette type, refers to the installation form of the flywheel is locked on the hub through the card base, which overcomes the problem of difficult disassembly of the rotary hub.

The following picture shows the anatomy of the structure of the ball card hub

The picture below shows the needle roller bearing cassette hub

General structure of bearing hubs:

To buy a hub, you have to know that your frame opens at the rear and the fork opens, so that you can choose the hub shaft length, but now the mountain frames on the market are a standard, the front gear is 100mm (of course, it refers to the fork's open gear), and the rear gear is 135mm; For bicycles of different speeds, the flywheel installation method below 7 speed is screw-on type, and the cassette type is above 8 speeds; It is necessary to know the number of holes on the rim of the hub you have selected, which determines the number of holes on the rim; Whether it is a quick-release hub or not, there is no explanation; What kind of brake type of hub is used, disc brake hub has disc brake pad fixing surface and mounting hole at one end of it, disc brake type hub can be used for V brake (as long as the frame has V brake seat, the rim has V brake edge), and V brake special type can not be used for disc brake. As for whether the ball type or the bearing type is better, it will not be discussed here.

The hub in a bicycle refers to a drum-like object in the center of the wheel.

The hub is equipped with bearings and axle rods, which are connected to the frame by axle rods. The exterior is connected to the rim by a bar and is the heart of the wheel. Because the shape is very similar to the folk drum beaten, it also has the name "flower drum".

The hub is shown in the figure below:

That's right, the hub is what you call the whole part that connects the spokes to the axle, because when the whole thing stands up, it looks like a knocking hub.

The Shimano Deore-LX is a series codename that has a lot of parts, including hubs, and it's up to you to decide whether to replace the hubs or not.

Wheels in the traditional sense consist of hubs, spokes, and rims. The hubs generally need to be replaced if the spokes are replaced, and the only thing left is the rim, as long as the number of holes (common wheels have 32 and 36 holes) are suitable, you can keep them, and you can decide whether the performance and appearance are in line with it.

In addition, the LX kit has been replaced, and the wheelset is usually changed (the wheel set with spokes braided by the brand manufacturer). Generally speaking, wheelsets have a greater aerodynamic advantage. However, mountain bikes are generally not very fast, and making your own is also a good way to save money.

The proper name of the hub in the bicycle should be called the flower wheel, that is, the bearing of the wheel and the rim through the spokes to form a wheel group.

The hub is the bearing of the wheel, because it looks like a knocking hub when it stands up as a whole, so it is called a hub.

Bicycle hubs, also known as bicycle axle skins. The materials are mainly made of aluminum and iron, and some are made of titanium. It is a bicycle and a core component, which is mainly composed of hub shell + tower base, and is equipped with steel wire to form a wheel set

Flower Hub**

It's the front and back axles, just ask the old man.

There are many types of hubs, and there are generally them.

1. Cassette flywheel hub and rotary flywheel hub cannot be used both. (If the flywheel is cassette, you can only use the cassette hub.) If the flywheel is spinning, you can only use the spinning flywheel hub).

2, V brake hub and disc brake hub and roller brake hub and brake hub, (V brake hub can not be installed with disc, can not be used on disc brakes, but disc brake hubs can be used with V brakes.) Roller brake hubs are generally used for city cars and can be compatible with V-brakes. The brake hub is also used in city cars, which can be used on V brakes, but cannot be installed with disc brakes or roller brakes).

3. Hubs with additional functions, such as grinding hubs with power generation function.

Whether it can be used in your own car depends on whether the number of holes in the hub is the same as the number of holes in your rim, and you can use it if you are the same.

The second is to see if the hub matches your flywheel and brakes, and the matching one can be used.

The third is to see whether the length and thickness of the hub match your frame, and the thicker barrel axle hub cannot be installed on the general mountain bike

It's very troublesome to make your own hubs, and you can't do it without professional tools if you go to the car dealership to find a master to teach, and others won't want to do it. Therefore, if you want to ride a wheelset with a self-made hub, you still have to spend money to go to the car dealer to find a master to get more practical.

If you are determined to take the technical control route, then please complete the professional tools before it is too late. Look at the technical stickers and slowly grope for a few more laps, and you will naturally be self-taught. I wish you every success.

This is very difficult, I've seen others get it, and I can't understand it, so it's best to have someone show you a hand-in-hand demonstration.
