Spoke Dope is a non toxic made in the USA product that was a collaboration between Stoic Wheels and ZUMWax. It is a thread preparation product designed specifically for spoke threads. A blend of teflon, acrylic resin, and different types of waxes, Spoke Dope is invaluable in the preparation of spoke threads for wheel building. Even if you are only building a few sets of wheels at a time, Spoke Dope will work for you. It is water based, and can be brought back to life with just a few drops of water, rather than clumping and having to be disposed of. Comes packaged as TWO 20ml bottles of different colors to help you keep your spoke lengths separated.
