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 the 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.
