DID 525 VX X-Ring Chain

DID's VX Chain uses patented X-ring seals. Like O rings, X rings function to seal in lubrication and keep dirt out.

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 an O-ring chain and 36 times that of a DID standard chain; this means more resistance to stretching, bowing and warping, and smoother handling. With proper maintenance, an X-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.
