KMC Chain 525EXR - Chain Road chain

In chain manufacture, outstanding metal finish products result from skilled engineering of heat treatment.

In AM Cross Ring chain series, it is adopted the world-class level of heat treatment technology to enhance chain strength and durability.

In addition, developed grease is well-retained between solid bushing and hardened pin to achieve the operation condition.

The special cross-shaped ring stops grease to vanish over time, so lubrication lasts longer to constantly reduce friction damage.

AM Cross Ring chain stay with you to conquer the most severe and harsh condition and enjoy every riding moment.
