Specs At A Glance

Good To Know

Q: How do I know when the chain needs replacing? A: A chain that has stretched beyond the adjustment range, shows tight spots, or has damaged rollers should be replaced. Worn sprockets often accelerate chain wear, so inspect both together.

Q: Does this chain come with a master link? A: Yes, a master link is included so the chain can be installed without riveting tools. Match the link type to your sprocket setup before riding.

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