RNC Titanium Ceramic Mid Bottom Bracket Bearings 19mm, 22mm & 24mm Hats but by creating a tinyThe lightest & strongest bottom bracket bearings ever made for BMX! The Bearing races are CNC machined from heat treated & aged 6al 4v w a tensile strength of 170,00 psi then electroless nickel silicon carbide plated. The electroless nickel creates a layer of 70 Rockwell plating w the silicon carbide nano particles being a 9. 5 on the mohs scale; nearly as hard as diamond for a long lasting bearing life. The balls are Silicon nitride Si3n4. These are
