V-Twin Visionary talks about Lyndall Brakes Rotors and Brake Pads

Lyndall Bow-Tie cut rotors. These are similar to the Crown Cut design, but with significantly less weight and better outgassing. The Bow-Tie cut friction rings are also designed to provide better stopping power. By reducing the surface area where the brake pads make contact with the friction ring, clamping power per square inch is increased.
