* Tá an táirge déanta de AL7075-T6 bhabhta bar CNC. Tá sé críochnaithe le scian Diamond, tá Diamond-mhaith uigeacht miotail, agus is é an chuma ar an táirge resistant a innéacs cuimilte. Gach go maith. Glacadh leis an allmhairithe líneáil liathróid cruach na Seapáine, tá an uainíocht aon friotaíocht, a laghdaíonn go mór an fhriotaíocht frictional agus a fheabhsaíonn an éifeachtacht marcaíocht.
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.
