Mountain biking with inadequate brakes is terrifying, if not downright unsafe, but the role of pads and rotors is often underappreciated. So we sat down with Daryl Simmons of Galfer USA to go deep on brake pads and rotors, including differences in pad materials and why the classic metallic vs. organic debate doesn’t tell the whole story; what factors influence wet-weather performance and heat resistance; rotor design and how to think about choosing rotor sizes; and a whole lot more.
