hey,
say you cleaned your bike one day including taking off the chain and you left the good quality (middle tier shimano) chain outside on the patio and forgot about it and due to all the bad weather keeping you off the bike you only stumbled across it about 3 weeks later to find it all rusty...can the chain be brought back to life somehow?
obviously i would never be this careless, it's just my mate said this is what happened...
my mate would appreciate any constructive feedback thanks,
