DID 525 VX X-Ring Chain Gold and Black

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.

JT Sprockets

JT front sprockets are made with SCM420 chromoly steel alloy, while the rear sprocket is manufactured with ultra-durable high-carbon C49 steel.

DID 525 VX drive chains are always supplied 'open' with a rivet link (included). You will need a specialised tool in order to rivet the chain, or take it to a mechanic who can do it for you. A spring link is available, but a spring link has only 65% of the strength of a rivet link and therefore, a rivet link is always recommended.
It is important to periodically inspect and lubricate the chain to maximise chain life.
