This is a KMC "Drop Buster" chain
* 1/2" X 3/32"
* GUN METAL BLACK (a true black.. not bronze)
* Model number is Z610HX
* 113 links
* Comes with matching master link
* Great stretchproof chain for any single speed application with a 3/32" drivetrain (BMX, Fixie, cruiser, etc.)
* NEW IMPROVED VERSION: This chain now comes with an "offset link" installed on one end. This is basically a half-link. It allows you to more accurately size the chain to your drivetrain. This is especially important if you have very short drop outs. If a full-link adjustment gets you to the right length, just remove the end with the offset link. If you need a half link adjustment to get your chain to the right length, keep the end with the offset link and remove the end with the full link. You can still use the master link that is included for either scenario.
