Disc for Bicycle Brakes

When choosing brake discs for your bike, it's important to consider several factors, such as disc diameter and mounting type. Brake discs can vary in diameter from 160 mm to 180 mm, and it's important to choose the appropriate diameter.
As for the type of mounting, there are two main options: centerlock and 6-hole. Of these two systems, the 6-hole is the more traditional.
