* Bidhaa hii alifanya ya AL7075-T6 duru bar CNC. Imekwisha kwa kisu almasi na ana almasi kama chuma texture. muonekano wa bidhaa ni bora. Anta Japan nje ya chuma mpira bitana, mzunguko hana upinzani, ambayo hupunguza sana upinzani frictional na inaboresha farasi ufanisi.
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.
