KMC Z610HX chain
Like the Z510HX, the Z610HX is the same heavy-duty chain as the Z510HX, featuring the same super-strong mushroomed pins and heat-treated side plates but has a narrower 3/32" width.
Includes a pre-installed half-link to dial in optimal chain length and get your wheel slammed up real tight against your seat tube.
FYI: KMC recently changed the name of this chain from Z610HX to 'Z1EX Narrow'. Some packaging may show the new model number.
• 1/2" x 3/32"
• 113 links (including the half-link)
• colors: silver, gun metal grey, copper
This chain WILL NOT work on 1/8" cogs & chainrings!
