There is no clear standard for when to replace a sprocket, making it very ambiguous.
One factor to consider is "wear on the teeth."
It's time for replacement when the tips of the teeth become sharp, or the belly or sides are worn down.
Replacing the front and rear sprockets and chain simultaneously If you only replace one of them, the worn parts that haven't been replaced will prevent the new parts from performing at their original potential and durability, leading to an earlier replacement time. Therefore, considering the long run, replacing all three simultaneously is recommended for longer lifespan.
This is a rear sprocket (wheel side).
To enable fine-tuning, it supports tuners with a wide range of tooth counts and reasonable pricing.
Made from high-tensile chromoly steel, boasting high durability.
Sprockets are consumables.
As a general guideline, inspect your sprocket approximately every 1000km of driving (with daily lubrication, the lifespan of the sprocket and chain will significantly increase).
Rear sprocket tooth count ÷ front sprocket tooth count = reduction ratio. A larger number indicates an acceleration-focused type, while a smaller number indicates a top speed-focused type.
