From the original Interlock half-link chain that changed BMX drivetrains forever in 2003, Shadow has always had one goal, to create the best BMX chains ever made. 13 years later and we can confidently say we have done that. With our tried and true Interlock V2 and the introduction of the unparalleled Supreme chain, Shadow has pushed the limits of chain technology far beyond our closest competitor. Utilizing a forging process in the link construction, the Supreme Chain is incredibly strong, not only in sheer tensile strength but also in the grinding and bashing department. The forging process actually makes the material stronger and more resistant to damage. The strongest and most unique chain ever made for BMX. Now with a Limited Lifetime Warranty!
