Formerly Z610H, the KMC Z1 EPT chain offers excellent shifting for single-speed drivetrains such as BMX or Fixie, albeit without rollers. It features anti-drop technology to prevent derailment, and reinforced rivets for extra strength, ensuring optimum durability and flexibility. It features EcoProTeq treatment, which doubles rust resistance compared with conventional anti-rust treatment. The advantages of EPT coating are that it is less noisy, performs better, is more resistant to rust and retains its good looks.CHARACTERISTICS:- Wide chain- Dimensions: 1/2" x 1/8"- Links: 96- Rivet length: 8.6 mm- Weight: 368g- Link attachment rapide included
