The timing for replacing a sprocket is very ambiguous, with no clear standard.
Among the factors to consider is "tooth wear."
When the tooth tips become pointed, or the belly or sides are worn down, it's time for a replacement.
Simultaneous replacement of front and rear sprockets and chain: If you only replace one of these parts, the worn unreplaced parts will prevent the new part from performing optimally or having its full lifespan, leading to an earlier replacement. Therefore, considering the long run, replacing all three simultaneously is recommended for better longevity.
This is a rear (wheel side) sprocket.
To enable fine-tuned settings, we support tuners with a wide range of tooth counts and reasonable pricing.
Made from high-strength chromoly steel, boasting high durability.
Sprockets are a consumable part.
As a general guideline for normal driving, inspect the sprocket approximately every 1000 km (regular lubrication significantly extends the life of both sprockets and chains).
Rear sprocket teeth ÷ Front sprocket teeth = Reduction ratio. A higher number indicates a focus on acceleration, while a lower number indicates a focus on top speed.
