My Litespeed is getting noisy, and its the rear hub. I swapped the rim to another bike and the noise was still there, so I know its the hub. So touch a little oil in the dust cap area around the moving part - solved this problem for two weeks. Now its back again, and it sounds like a rusty chain/dry chain - not to loud but its always there and its very irratating. I will take it to the shop, but any ideas of what internal problems it may be presenting?
