What's the difference between o-ring and normal chains?
o-ring chains last longer (if you lube 'em the same). They're more
expensive and may need a special lube. Check that the lube you buy specifies
that it is OK for O-ring chains. Some lubes eat the o-rings and destroy the
chain (not sure you can still buy lubes like this these days actually!)
