This is just a question about chains in general. As I first though mine was lacking in Lube, so having first put wd 40 on it (the jockey wheel cage was jumping forward slightly at one point on revolving the chainwheel backward) I find it strange that it was doing it just in one position. So having put some WD 40 on the chain at that point contintued to revolve backward, this seemed to make t somwhat less jumpy but the chain seems still a little noisy and some vibration in the Jockey wheel hanger still though I have put more chain lube on it, I'm wondering now if the rear derailluer needs slight adjustment? Though gears seem to change fine also has anybody had problems with the T3 chain going rusty Though I've always lubed the chain links and it always seems that whenever I touch the chain I get oil off it I have had the chain off about 4 weeks ago and soaked it in paraffin then lubed it up again but it still has signs of rust showing on the outside of the sides of the links But not all of them I've cleaned them off once as I said, but they the rusty patches have come back again so perhaps I should invest in a new chain of better quailty?
