These are Yokozuna brand with the Scott/Mathauser salmon-colored compound which is the most durable, grippy, fade-resistant of all. They say it's the best in wet weather, but it certainly works great in dry weather too, and you can consider these pads upgrades to any brake they'll fit on. Two styles: 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 easypeasy pad replacement. Long 73mm long pads.
