Tech Tip 24 Why O Ring chains Wear out
If you want to accelerate wear in an O-ring chain, leave it dry and rusty. As external corrosion, i.e. rust, builds up on the chain, and the inner part of the sideplate that contacts the O-ring becomes rough from rust, it quickly abrades away the O-ring until it is cut and the broken piece is forced out from between the inner and outer sideplates. This opens up a pathway to the outside for the external lubricant to escape as well as for water/dirt entry.
The external lubricant you apply must not be sticky or dirt will be attracted to the chain and the O-rings can be cut by a sharp piece of debris, like sand. My preferred O-ring chain lubricant is Maxima Chain Wax. “Why is my sticky chain lube rated for O-rings? It says so on the can?” All that means is the chemicals in the can have been tested to not deteriorate the rubber of the O-rings and cause cracking and hardening.
