Do disc brake road bike discs need to be replaced? -Kootubike sharing

Many riders will be curious, that is, how should I judge whether the disc on my car needs to be replaced?

The rotors on a disc brake road bike may need to be replaced after a period of use. The degree of wear of the disc depends on the frequency of use, road conditions, climate and other factors.

Generally speaking, when the disc is worn to a thickness less than 1.5mm, it needs to be replaced. Also, if a disc is cracked, warped, scratched or otherwise damaged, it needs to be replaced immediately.

Regular inspection and cleaning of discs can prolong their life and ensure the performance of the brake system. If you are unsure whether you need to replace your rotors, it is best to consult a professional bicycle mechanic or repairman.
