There is no clear standard for when to replace a sprocket, making it a very ambiguous decision.
The determining factor in such cases is "tooth wear."
When the teeth become sharp, or the belly or sides are worn down, it's time for replacement.
Simultaneous replacement of the front and rear sprockets and the chain If you only replace one of these components, the worn parts that were not replaced will prevent the new parts from performing at their full potential and durability, leading to an earlier replacement time. Therefore, considering the long-term, it is recommended to replace all three simultaneously for better longevity.
This is the rear sprocket (wheel side).
To enable fine-tuned settings, we support tuners with a wide range of tooth counts and reasonable pricing.
Made from highly durable chrome molybdenum high-tensile steel.
Sprockets are consumables.
As a general guideline for normal driving, please inspect the sprocket every 1000km (regular lubrication significantly extends the lifespan of both sprockets and chains).
The larger the reduction ratio (rear sprocket tooth count ÷ front sprocket tooth count), the more acceleration-oriented the setup; the smaller the number, the more top speed-oriented.
