These are Yokozuna brand with the Scott/Mathauser salmon-colored compound which is the most durable, grippy, fade-resistant of all. The best in wet weather, but it good in dry weather too, and you can consider these pads upgrades to any brake they'll fit on. Two styles: Smooth POST, for cantilever brakes that require posts (not all do); and THREADED, for normal sidepulls and centerpulls that use threaded shoes. There you go. Both are cartridge shoe style for easy pad replacement. Long 73mm long pads.
