* Dan il-prodott huwa magħmul minn AL7075-T6 tond bar CNC. Huwa lest ma 'sikkina djamant, għandha metall nisġa bħad-djamant, u l-apparenza tal-prodott huwa reżistenti għall-indiċi frizzjoni. Kollox sew. Tadotta l-Ġappuniż inforra ballun azzar importati, ir-rotazzjoni m'għandha l-ebda reżistenza, li inaqqas ħafna l-reżistenza frizzjonali u ttejjeb l-effiċjenza riding.
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.
