Feature: 1. Aluminum Alloy Material: All aluminum alloy material, strong and impact resistant, riding more assured, the surface layer is anodized, effectively protecting the aluminum alloy body, anti corrosion and anti oxidation. 2. Wear Resistance Bearing: The force is not easy to change shape, cold resistance, high temperature resistance, wear resistance and corrosion resistance, high transmission efficiency, and more labor saving riding. 3. Positive and Negative Tooth: Bicycle rear derailleur pulley can reduce the lateral virtual position, which can shorten the shifting response time and improve the shifting performance to a certain extent. 4. Deep Toothed Guide Wheel: The deep toothed guide wheel optimizes the inclined tooth profile and synchronizes with the chain transmission direction, making the chain entry and de chaining smoother. 5. Good Workmanship: CNC machined and finished with a knife, the appearance of the product has a good wear resistance index. Bike rear derailleur pulley fits for bike of 12T and 8, 9, 10, 11 speed.
