Weights install using a stainless steel set screw which allows for exact positioning and unlimited re-use without the risk of spoke or wheel damage caused by conventional hammer-on weights Uniform diameter allows multiple weights to be stacked on a single spoke if necessary to achieve the most precise balance Weights attach directly to the spoke - not the spoke nut - so they can be used with conventional and outer-spoke wheels Precision CNC-machined re-useable spoke wheel weights Made in the U.S.A..
