Can anyone tell me the weight difference from a 530 O-ring chain to standard chain.
Also if the 0-ring is heavier does it affect performance.
Thanks

Weights are pretty close really. Some will say o ring (what I run) costs power but once it gets warmed up, it is free as standard chain. O ring is a little more forgiving maintenance wise. Either way, most important things to remember is keep them clean and lubricated. I lube mine 2-3 times per event just to be safe.

what do you use for lube. Will motor oil

Motol chain spray. Their cleaner works well too.
