Patented X-Ring
The VX chain series showcases the industry-leading, patented X-Ring seal technology, which leads to extended chain life, minimal friction, and overall amazing performance.
D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss. X-Ring is a U.S.A.
