Brake disc for a bicycle 

The Exifun brand is focused on products related to entertainment and active recreation. The bestseller of this brand is the Exifun glider.

A bicycle brake disc is a critical part of a bicycle's braking system, allowing the rider to safely and effectively slow down or stop the bicycle.

Brake disc function

The brake disc serves to create friction between the brake pads and the disc, which slows down or stops the rotation of the bicycle wheel . Brake discs are made from a variety of materials, including steel, stainless steel, aluminum, and composites. The material affects the brake performance and the corrosion resistance of the disc. Brake discs come in different diameters, which affects braking performance. Larger discs tend to provide better braking performance but can be heavier.

Types of brake discs

There are different types of brake discs, such as:

• discs with one or more discs

• discs with different types of ladders and patterns to increase the braking effect

Brake disc selection and maintenance

When choosing a brake disc , it is important to ensure its compatibility with the specific brake system of a city or mountain bike , including the type of brake pads and brake pins. The brake disc should be regularly inspected and cleaned to remove dirt and oil that could affect braking performance . The brake disc must be resistant to the high temperatures that occur when the bicycle is braked, and maintain its effectiveness even during long descents.

Types of brake discs

Brake discs for bicycles are produced in different variants and materials, which affect their braking performance, weight and durability . For example:

• Steel brake discs : Steel discs are the most common type of brake discs on bicycles. They are affordable and provide reliable braking performance in a variety of weather conditions. These discs can have different thicknesses and patterns to improve braking performance.

• Stainless steel discs : Stainless steel discs are more resistant to corrosion and can maintain their appearance for a long time. They are often used on bikes that are exposed to damp and wet conditions.

• Aluminum brake discs : Aluminum discs are light and provide good braking performance. They can be particularly suitable for bikes with light frames where weight is a key factor.

• Ceramic brake discs : Ceramic discs are extremely light and have high heat resistance. They provide excellent braking performance and are popular among performance and sport bikes. However, they are more expensive and more prone to damage when dropped.

• Carbon brake disc e: Carbon discs are light and have high braking performance. They are popular with mountain bike racers and cyclocross bikes. However, their price is at a high level.

• Floating discs : Floating discs have a central part that can freely rotate around the axis of the disc. This design improves the cooling effect and removes heat faster, which increases braking performance.

• Perforated and grooved discs : Discs with perforations or grooves have an increased surface area, which improves heat dissipation and braking performance. They are often used on bikes intended for downhill or road races.

Which brake disc to choose?

Cyclists often choose discs based on weight and their performance requirements. Some prefer lightweight discs for increased agility, while others prefer discs with a powerful braking effect. Choosing the right type of brake disc depends on the type of bicycle, riding style, required braking performance and personal preferences of the cyclist. It is important to consider all these factors when choosing discs to achieve optimal braking performance and cycling safety.
