Optimized narrow-wide tooth design, increasing shifting speed, decreasing friction resistance, enhancing chain stability, suppressing shifting noise.
if you hear shifting noise from a narrow-wide tooth pulley louder than that from a normal tooth pulley, it’s most likely caused by poor design of tooth angle or poor process. Just remember, noise is not good, the lower the noise the better.
