Chain KMC Z1eHX, nickel-plated, 1 speed
KMC has developed Z1eHX chains with focus on e-bikes, but they find use on all single speed drivetrains.
Thanks to special heat treatment, wider and thicker plates, those chains are more resilient and durable than any other. Nickel plating also ensures excellent rust resistance.
All in all, less stretching and wear means smoother ride and longer replacement intervals.
