* Ev berhema ku ji AL7075-T6 bar dora CNC kir. Ev bi kêr diamond qedand û nîgarê metal-diamond wek. Peydabûna vê berhemê baş e. Pesindkirina Japanese derhanîn çermê ball polayê de, rotation has no berxwedan, ku gelek berxwedana frictional kêm dike û ji bo pêşvebirna berevpêşbirina riding de.
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.
