RK Chain MRU420 U-Ring Clip Link

The RK MRU U-Ring Chain features a proprietary ultra-thin seal (U-Rings) where the thickness of the seal is less than 50% of the most common O-ring seal. This allowed RK to design a sealed chain with the same weight as a non-sealed chain. The MRU features a chain life over four times longer than comparable non-sealed 420 chains while also requiring less chain adjustments.
