Overview
A KMC Z7 chain replaces a worn one on a bike with the lower speed counts. Chamfered inner plates help it shift between cogs, and a joining link closes the loop.
Chamfered plates are the shifting feature, and the closing link is in the pack. It matches the lower speed counts only, and the sizing data in the specs is partly junk.
Who it's for
Older bikes with that narrower speed range are the target. Newer bikes with narrower chains need a different chain.
Pros and cons
- Chamfered inner plates
- Joining link included
- Alloy steel build
- Only for lower speed counts
- Chain length may need trimming
- Some spec fields look wrong
Performance notes
Chamfered inner plates guide the chain across cogs, and the pitch and width must match the sprockets. A joining link lets the chain be closed or opened at the right length.
