There are no clear criteria for when to replace a sprocket, so it's a very ambiguous process.
One factor for judgment is "tooth wear."
It's time to replace the sprocket when the teeth become pointed or the belly or sides are worn down.
Replacing the front and rear sprockets and chain simultaneously: If you only replace one of the three parts, the worn parts that were not replaced will prevent the new parts from performing at their original capacity and durability, causing them to wear out prematurely. Therefore, considering the long term, replacing all three parts simultaneously is recommended as it will last longer.
This is the sprocket for the rear (wheel side).
To enable detailed settings, it supports tuners with a wide range of teeth and reasonable pricing.
Made from highly durable chrome molybdenum high-tensile steel.
Sprockets are consumables.
As a general guideline for normal driving, inspect the sprocket approximately every 1000km (regular lubrication significantly extends the life of the sprocket and chain).
The larger the reduction ratio (rear sprocket teeth ÷ front sprocket teeth), the more acceleration-oriented the bike is; the smaller the ratio, the more top-speed-oriented it is.
