Jopwkuin 12T Sealed Bearing Bicycle Wheel - Anti-Oxidation & Corrosion Resistant Rear Derailleur Pulley for Road Bikes (Red) - Perfect for Smooth Gear Shifting & Enhanced Cycling Performance

Feature:1. Aluminum Alloy Material: All aluminum alloy material, strong and impact resistant, riding more assured, the layer is anodized, effectively protecting the aluminum alloy body, 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: 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 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.Specification:Item Type: Bike Rear Derailleur PulleyProduct Material: Aluminum AlloyProduct Style: 12TProduct Application: 8/9/10/11 SpeedWeight: Approx. 15g / 0.5oz Package List:1 x Rear Derailleur Pulley 2 x Reducing Sleeve Tube
