1. Using 7075 high-strength aluminum alloy, CNC machining, anodizing, wear-resistant and durable2. Ceramic bearing is smoother, reducing friction and higher strength3. Deepen the tooth marks, effectively reduce the chain drop, the speed change is clearer, and the winding is more stable4. With 2 reducing sleeves, more compatibility and flexible rotation5. Material: high strength aluminum alloy + ceramic bearing6. Specifications: use 4/5/6mm shaft guide wheel7. Scope of application: support most rear dials, support 8/9/10/11 speed8. Guide wheel selection rules: Please try to choose the same size as the original guide wheel. There is no same size. You can choose a smaller than the original guide wheel, but you cannot choose a larger one.9. Size: 11T diameter is about 41mm, 13T diameter is about 49mm10. Weight: 11T about 6.9 grams, 13T about 7.7 grams
