Good To Know

Q: Does this chain come with a master link? A: This listing covers the chain itself; confirm whether a master link is included before ordering, since chain type and connector style vary by supplier. Q: How often should I lubricate a standard chain? A: Non-sealed chains need more frequent cleaning and lubrication than O-ring types, especially after wet or dusty rides.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
