Regina ChainRef : REG0004 / 520-ZRA-110

The BLACK DUAL chains are natural steel in colour and are available only in sizes 520 and 525.

Manufactured with high carbon content alloy steel components, solid bushings and rollers, plates, pins, and shot-peened rollers for high fatigue resistance.

Laser marking on the outer plates to identify the size, model, and origin.

Subjected to a pre-stretch that enhances performance, particularly thanks to the Z-Ring seals, BLACK DUAL chains guarantee high mileage, reduced elongation, and extended lubrication intervals.
