RK XW-Ring, Gold RKJ 530 Rivet Link

RK gold-plated rivet master link for RK 530 chains. Features XW-ring sealing which provides better lubrication retention than standard O-rings. The rivet design creates a permanent connection once installed. Compatible with the RK GXW 530 chain used on the Rush SR. Gold plating provides corrosion resistance. XW-ring design reduces friction and extends chain life compared to standard O-ring chains. This is a replacement master link. Once installed, rivet links cannot be reused if the chain is removed.
