The gold Regina Z-ring chain is the longest lasting chain on the market today.
The superior design of this chain makes for added longevity in the harshest riding conditions such as mud or sand.
The new generation of these seal rings have a special designed conical shape on their inner side.
The 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.
The conical section enhances the assembling on the bushing because lubricant is trapped between the plates and the lobes of the rings, thus keeping the ring lubricated and increasing its life.
If you want the top of the line chain, look no further.
