    Lateral Movement of chain any indication of quality?

    Hi all, I've got an IRD 9speed chain on my 9x3 road bike that is very loose laterally. It shifts fine and doesn't measure more than 0.25 on my Park CC-2 chain checker. This reading is the low end of the spec for a new chain (on the tool it says: new chain .25-5, replace <1.0). The side to side movement is very obvious compared to the Wipperman that I previously had. It actually makes slight cross chaining type combinations run silently, which I see as a plus.

    Just wondering if others have experienced variations in lateral flex on chains. Which brands have more side flex in your experience, and which have less?

    I used to think side flex indicates a worn-out chain, but apparently, this is not the case.

    Lots of chains are flexible and many of the narrower ones used now are more flexible than wider chains of old. If it shifts, I'd not worry about it.

    Lateral play doesn't indicate anything.

    Lateral play indicates that you have a chain designed for derailleur gears
