NOTICE!  Please Read The Following Important Product Notes:

• These chains come in 120 link lengths only. They can be cut down fairly easily.

• D.I.D X-Ring reduces friction by twisting between the side plates instead of being squashed.
• Normal O-Rings and other makers' modified O-Rings have squashed points that increase friction.
• The twisting resilience of the X-Ring's four sections greatly increases its sealing performance.
• This keeps the dirt out and the lubrication in much better than any other O-Ring.
• X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
