Drive Sprocket Rear 41T 420 Size NS50F NSR50

[KITACO 535-1036241 Drive Sprocket Rear 41T 420 Size NS50F NSR50 KITACO 535-1036241] The replacement timing for sprockets is very ambiguous, with no clear standards. Among the factors to consider is "tooth wear." It's time to replace a sprocket when the teeth become pointed, or the belly and sides become worn down. Simultaneous replacement of front and rear sprockets and chain: If you only replace one of these three parts, the worn-out parts that were not replaced will prevent the new parts from performing optimally and lasting as long as they should, leading to premature replacement. Therefore, in the long run, it is recommended to replace all three parts simultaneously for better longevity. This is the sprocket for the rear (wheel side). To enable precise tuning, we support tuners with a wide range of teeth counts and reasonable pricing. Made from highly durable chrome molybdenum high-tensile steel. Sprockets are consumables. As a general guideline for regular driving, inspect your sprocket every 1000km (regular lubrication significantly extends the lifespan of both sprockets and chains). Rear sprocket tooth count ÷ front sprocket tooth count = reduction ratio. A higher numerical value indicates an acceleration-focused type, while a lower value indicates a top-speed-focused type.
