* 14T yopapatiza lonse dzino kalozera gudumu kulemera: 12g
* Zinthu Zofunika: AL7075-T6 zotayidwa aloyi CNC Machining
* Unsembe kukula: 6MM / 5MM / 4MM
*outside diameter 57.5mm
* Mtundu: Anode wofiira, enamel, buluu, golide, titaniyamu
* Kuchitira: zitsulo mpira / hybrid ceramic zimakhudza / ceramic Kuchitira
* Mbali ya ntchito: kwa m'munsi kalozera gudumu la kufalitsa, chonde ntchito 12T yopapatiza lonse dzino kalozera gudumu ndi pulley izi.
* Mankhwala uwu wapangidwa AL7075-T6 wozungulira bala CNC. Kwatha ndi mpeni diamondi, ali diamondi ngati zitsulo kapangidwe, ndi maonekedwe a mankhwala kugonjetsedwa ndi mikangano index. zabwino zonse. Motengera Japanese kunja zitsulo mpira akalowa, ndi kasinthasintha alibe kukana, zimene zimachititsa kwambiri kukana frictional ndi bwino kukwera dzuwa.
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.
If your chain is rubbing against your cage after installing larger pulleys, just remove or re-shape the cage, shown as below.
