What is a bicycle sprocket? How many types are there? Pros and cons of each type

The clutch is an integral part of a bicycle’s transmission system. Good tires will help the bike operate smoother and more smoothly. Please join Tnhelearning.edu.vn to find out what a bicycle cassette is and how many types it includes!

What is a bicycle sprocket? Structure of a bicycle cassette

Bicycle clutch is a part of many serrated discs arranged in layers on top of each other. In order for the bike to move according to the user’s will, the cassette will receive the movement from the disc through the chain and transmit it to the rear wheel to help the wheel move forward in the right direction.

Bicycles with more than 1 cassette will be equipped with a handle to help users easily change the cassette while on the move. Choosing the right cassette will help the driver save a lot of energy and better control speed when climbing, downhill or running on the road.

Bicycle clutch is an indispensable part of the transmission system to help the bike move smoothly and smoothly

Bicycle clutch consists of two main parts:

• The cassette (1): is a set of cascaded gears located on the center of the rear wheel, including the outer gear and the inner gear in the form of a serrated tooth inclined to one side, which meshes with the sprocket (2) is a blade. small steel.
• The cassette (3): has two grooves to place 2 gears, in each slot there is a small spring or a lever made of elastic small steel thread and always leans on the gear.

The sprocket consists of two main parts, the rim and the sprocket

Classification of bicycle cassettes

The number of gears is the criterion for classifying bicycle cassettes. The more gears the bike has, the more speed it will have, such as 8, 9, 10 or 11 speeds . When changing the speed through the cassette, you also have to pay attention to the number of discs to change accordingly, ensuring compatibility with the system and the desired speed.

The larger the number of gears on the disc, the lighter the pedal will be, and vice versa. On the market today, most road bikes will be equipped with 12-25T cassettes , where 12 is the number of teeth of the smallest sprocket and 25 is the number of teeth of the largest sprocket.

So, depending on your needs and traveling terrain, you can consider and choose for yourself a bike with the right number of cassettes.

The bike has 1 disc and 10 cassettes that make up a 10-speed drivetrain

Uses of bicycle cassettes

The smooth coordination between the disc and the cassette will create a powerful transmission system that meets the needs of the driver. Especially when facing a difficult terrain, steep slope, lots of rocks or mud, the cassette needs to play its role well and coordinate well with the plate.

If the transmission is the engine of the motorcycle, the disc and cassette system is the raw engine of the bicycle. The user applies thrust to the pedal, the disc in combination with the cassette and chain will transmit kinetic energy to help the wheel move forward.

You can flexibly change the number of discs and cassettes through the handwheel

Notes when choosing to buy bicycle cassettes

To move safely and optimize pedaling force, users need to choose a vehicle with the right number of cassettes to suit their needs and flexibly adjust the number of cassettes to suit each terrain:

• When riding on flat roads : For flat or long roads, you should choose medium sized discs and cassettes, about 17 – 19 teeth . With enough pedal force, the bike will always move stably and firmly.
• When climbing slopes : You should choose small discs and large cassettes (in terms of size). The larger the number of teeth on the cassette, the lighter your pedaling force, the less strenuous climbing journey and helping you to be more persistent to conquer the terrain.
• When going downhill : On the contrary, at this time you should choose a large disc and a small cassette (in terms of size). When going downhill, the bike will rush with inertia, so this option will help you slow down the speed of the vehicle, limiting problems on high and dangerous slopes.
