All double rollers are not created equal
"All double rollers are not created equal" This is true and if you want the best, indeed buy a "true roller chain". As the picture shows using a needle nose pliers I can twist the barrel and the link twist with the chain, this is extra wear on the pins and gear sets. Now with a true roller there is an extra barrel around the pins that rolls easily, less friction, less heat and less wear. So double rollers chains may not be what you expect, true roller is what you should use.
