Designed and developed to withstand the severe stresses caused by off-road riding, these chains are produced as either standard, or with Z-Ring or O-Ring seals to extend lubrication intervals, while maintaining a low pin length and light-running characteristics.
Assembled with high carbon alloy steel, solid bushings, shot-peened plates, pins, and solid rollers to reach a high fatigue limit.
IMPORTANT NOTE: In many cases, Regina chain is stocked in bulk and can be cut to length. If the length you require is showing not in stock, we will be happy to cut your chain for you.

-- Z-RING --
An evolution of previous X-Ring and Z-Ring designs, the new generation Z-Ring seal has been patented since 2003 and features a specially-designed conical shape on the inner side.
The Z-Ring flexes when assembled, creating a spring effect that guarantees the seal will not decrease over time. The special Z-Ring section provides enhanced chain flexibility while the conical section enhances assembly on the bushing. The lubricant trapped between the plates and the lobes of the Z-Ring keeps the ring lubricated and increases its life.
