The Shadow Conspiracy Interock V2 chain is re-designed with rounded side plates for compatibility with 8T and larger drivers. Extra wide and heat-treated mushroomed pins, stronger rollers and heat treated side plates provide maximum strength and durability. The Shadow Interlock chain is wider than most 1/8" chains. It's not uncommon for the chain to ride more on the body for the driver instead of being fully supported by the teeth when new. This will smooth out over time.
