I hear everyone talking about o-ring chains and how great they are. I must be doing something very wrong. I have only tried o-ring chains a couple of times, many years ago, but in every case after 5 or 10 rides they start getting frozen links. I've tried lubing them after every ride (the chain lube said OK for o-ring on the label so I took their word for it) but this makes no difference. Has anyone else had this problem, or is it just my bad luck?
