DID 520 VX X-Ring Chain Gold/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.

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

Sealed Bearing 2RS - DDU
All the wheel bearing we supply are 2RS - DDU.
Double sealed and ready lubricated with premium grease for added protection against dirt and water ingress and are made of high strength AISI 52100 chrome steel components for the rolling elements and the inner and outer rings; to ABEC 1 dimensional tolerances and C3 radial clearance tolerance.
The bearings also undergo electronic noise and vibration testing according to ANSI/AFBMA Standard 13-1987.
Care And Maintenance
Although bearings are subjected to large amounts of stress and are continually being used to fulfil various duties, they are precision made and typically last a long time (bearing failure is often due to improper installation and fitting). However high-mileage bikes and dirt bikes, which are exposed to a lot of mud and water, can become vulnerable and require attention sooner than expected.
