Specs At A Glance

Good To Know

Q: Does this chain come pre-lubricated? A: O-ring chains are typically shipped with a protective grease coating, but applying chain lube before first use is still recommended for best results.

Q: Should I replace the sprockets at the same time? A: If the existing sprockets show hooked or worn teeth, replacing them along with the chain helps extend the life of the new drivetrain.

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