DID's ZVM-X Chain uses patented X2-ring seals. Like O rings, X rings function to seal in lubrication and keep dirt out, and for the ZVM range the X rings have been redesigned to offer even greater wear resistance - the best in the DID range - and even less friction than DID's original X Rings.
Where the cross-section of an O ring is circular, the cross-section of an X ring is X or cross-shaped. This gives the seal additional contact points compared to the O ring, offering superior sealing and protection against dirt and grit getting stuck under the seal.
In addition, when under pressure an O ring becomes squashed and causes friction. An X ring, when under pressure, diverts this pressure by twisting instead, so an X ring decreases friction between side plates and reduces power loss by 50% of any other type O-ring chain.
DID's X rings have 40% greater wear resistance than their regular X-ring chains (the VX range) and 40 times that of a DID standard chain. This means more resistance to stretching, bowing and warping and smoother handling. With proper maintenance, an X2-ring chain will last longer than any O-ring or unsealed chain.

Sealed chains require lubrication every 500km (300 miles) in order to prevent surface rust and ensure performance.
