The Z8.3 is a KMC chain built to run across 6, 7 and 8-speed drivetrains, a common choice for older or entry-level derailleur bikes.

  • Compatible with 6, 7 and 8-speed drivetrains
  • 116 links
  • Standard-plate construction for everyday reliability
  • A straightforward, well-priced replacement chain

If your bike's drivetrain is 6, 7 or 8-speed, one chain generally covers all three — this is KMC's chain for that range.

Not compatible with 9-speed or narrower drivetrains, which need a narrower chain.

KMC parts are covered against manufacturing defects. If an item fails from a defect in materials or workmanship, return it to Tune Cycles with your proof of purchase and we'll manage the claim with KMC on your behalf — no need to contact the distributor yourself. This is in addition to your rights under Australian Consumer Law, which apply regardless of any manufacturer's warranty.
