I May be acquiring a hybrid bike with an 8 speed Nexus hub. This bike has not been maintained throughout its life and although the bike is not a major problem-I have a few worries about the Nexus hub. It looks as though the bike has not seen any oil for a long time. Chain- and probably sprockets- is completely worn but the owner says he can only get 5 of the 8 gears. Haven't checked out by riding it but on the stand I can get all 8 gears.
So do these hubs need lubrication?- where? and what oil? That is my main concern as the rear wheel is covered in a rust film that looks as though it got there by oil that has dried out. There is NO oil film anywhere on the bike- let alone around that hub.
Don't want to put any work into the bike if the hub has had it.
