KMC Z1EHX Wide chain (formerly Z510HX)
The Z1EHX is a little more heavy-duty than the KMC S1, featuring super-strong mushroomed pins and heat-treated side plates.
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 Z510HX to 'Z1EX Wide'. Same chain, different name. Some packaging may show the old model number.
• 1/2" x 1/8"
• 113 links (including the half-link)
• colors: gun metal grey, silver, copper
