Sprocket replacement: There is no clear standard for when to replace sprockets, and it is very vague.Among them, the determining factor is ``wear of the tooth tips.''If the tips of your teeth become sharp, or the belly or sides become scraped, it's time to replace them.

Replacement of front and rear sprockets and chain at the same time: If you replace only one of the parts, the replaced parts will not be able to demonstrate their original performance and durability due to worn parts that have not been replaced, and the replacement period will be brought forward. Considering the future, it is recommended to replace all three parts at the same time because it will last longer.
