IIIPRO 6-Bolt Cooling Brake Disc Rotors 140 160 180mm Stainless Steel Durable for Mountain Road Folding and Commuter Bike NEW

Brand: IIIPRO Model: PN-28 Sizes: 140mm, 160mm, 180mm Net Weight: 140mm—71g, 160mm—88g, 180mm—122g (not including screws) Thickness: 1.8 mm (+0.3 mm) Specifications: 6-bolt Material: Stainless steel Surface Finish: Anodized Suitable for: Mountain bikes, road bikes, folding bikes, etc. Perforated design for heat dissipation, easy cleaning, and drainage The large, irregularly patterned perforations facilitate easy cleaning and drainage while reducing weight; the small perforations along the edges enhance heat dissipation. Anodized Surface Treatment Laser cutting produces cleaner, smoother edges. The rotor’s friction surface intersects with the brake caliper’s contact surface, a design that effectively enhances the rotor’s friction. Three sizes to choose from 140mm, 160mm, and 180mm are designed for light, moderate, and heavy-duty riding scenarios respectively, to meet your diverse needs. Important Notes: 1. Rotors are wear parts and are not covered by the warranty. Special Notes: 1. New rotors may wobble slightly, which is normal. This can be fixed using professional tools or by visiting a professional bicycle repair shop. 2. The minimum operating thickness of the rotor is 1.6 mm. Actual service life depends on usage patterns. 3. Do not touch the rotor with your hands after long downhill descents to avoid burns. 4. Avoid contact with oil or grease during daily use, as this can severely impair braking performance. 5. Check the rotor thickness regularly. If significant wear is observed, replace the rotor promptly.
