A MTB brake disc is an essential component to guarantee efficient, safe braking adapted to each type of practice. Their design varies depending on power requirements, heat dissipation and durability. Here is a detailed guide to the types, features and brands of MTB xc brake discs.
1. Types of MTB brake disc
a. Fixed disks
Description: One-piece discs, entirely made of steel.
Benefits :
Simple, affordable and robust.Little sensitive to vibrations (less noise).
Disadvantages:
Less efficient heat dissipation.Risk of deformation under high heat.
b. Floating discs
Description: Consist of two parts: a steel brake track and an aluminum center, connected by rivets.Benefits :
Better heat dissipation thanks to the aluminum center.Reduction of risks of deformation under stress.
Lightness.
Disadvantages: higher cost.
c. Ventilated discs
Description: Incorporate special fins or structures to improve air circulation.Benefits :
Optimal heat dissipation, ideal for long descents or e-bikes.Disadvantages: high price and extra weight.
d. Coated discs
Description: Discs with specific surface treatment (ceramic coating, anti-rust, etc.).Benefits :
Extended lifespan.Better performance under certain climatic conditions.
Disadvantages: often higher price.
2. Technical characteristics of a MTB brake disc:
a. Disc diameter
Common sizes are:
140 mm: For light cross-country or gravel.
160 mm: Versatile use (XC, trail).
180 mm: More power for trail, enduro and e-bikes.
200-203 mm: Ideal for enduro and downhill.
Choice according to the weight of the cyclist and the terrain:
The larger the diameter, the greater the braking power.
b. Compatibility with pads
The discs must be compatible with the pads (organic or metallic).
Discs designed for metal pads are more resistant to heat and wear.
Some discs are optimized for a specific type of pads.
c. Weight
Aluminum discs or discs with a floating center are generally lighter, suitable for practices such as XC.All-steel discs are heavier but sturdy, ideal for enduro or downhill riding.
d. Thermal resistance
Technologies like Ice-Tech (Shimano) or ventilated fins (Magura) improve heat management on long descents.e. Fixing
6 holes: Most common standard, compatible with the majority of hubs.Center Lock: Shimano patented system, easier to install, but requiring specific hubs.
3. Popular brands of MTB brake disc:

Descent: Ventilated or floating discs from 200 to 203 mm.
Consider your weight and riding style:
A larger disc is recommended for heavy riders or those going downhill at high speeds.Check compatibility:
Make sure your rotors are compatible with your hubs (6-hole or Center Lock) and your braking system.Regular maintenance:
Clean your records after each ride to prevent dirt buildup.Replace them as soon as they show signs of wear or cracks.
In summary
The choice of MTB brake disc depends on your practice, your equipment and your expectations in terms of performance. Brands like Shimano, SRAM, Magura, and Hope offer models suitable for all terrains and levels of practice.
