Feature: 1. Titanium alloy material, high strength, PVD coating coloring, fine workmanship, new structure, high strength, and strong stability. 2. Suitable for M6 disc brake calipers, titanium alloy materials, high strength, light weight, good performance, good mechanical properties, toughness and corrosion resistance. 3. Lightweight and weight reduction, the density of titanium is very low, but the hardness is great, and the strength is higher 4. The surface of the gasket is colored by PVD vacuum coating, and a coating composed of TIN, TIALCN and other compounds is formed on the surface of the gasket, which strengthens the surface hardness and makes the gasket beautiful and not easy to fade. 5. Inclined concave‑convex design, high degree of fit, stable structure, strong fastening force and high stability, which can be reflected in the process of high‑intensity riding.
