RK currently has five types of sealed-ring chains and each has its own features and benefits.
After several years of development, RK produced the XW seals which drastically improved the chain life and performance.

As racing expanded into several different genres, RK added the ultra thin U-Ring and UW-Ring.

Each seal is specifically designed for a particular use to provide the ultimate in rotating efficiency while providing longer wearlife.
