Therefore, considering the long-term, it is recommended to replace all three simultaneously for better longevity.\u003cbr\u003e\n This is the rear sprocket (wheel side).\u003cbr\u003e\n To enable fine-tuned settings, we support tuners with a wide range of tooth counts and reasonable pricing.\u003cbr\u003e\n Made from highly durable chrome molybdenum high-tensile steel.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a general guideline for normal driving, please inspect the sprocket every 1000km (regular lubrication significantly extends the lifespan of both sprockets and chains).\u003cbr\u003e\n 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.\u003cbr\u003e\n Compatible models: APE50\/100 Giorno Cub DAX\u003cbr\u003e\n MONKEY RT MAGNA 50 JAZZ and others\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
