Because Eagle Transmission is the first of its kind, fully integrated and interdependent system, the X0 Eagle Transmission (T-Type) Flattop Chain is much more than just a chain. Its unique flat design makes it the strongest chain we've ever made. With equal importance, it enhances the look of any super machine. These details matter. It has a Dark Polar finish specific to the X0, has been plated with currentless nickel and comes with a PVD coating for incredible corrosion and wear resistance. Fully approved for E-MTB use with fixed pins.
