Bianchi Bergamo Transmission Question (s)
I am not total newbie to bikes, having converted a few 3 speeders to 18s speeds, etc; however, I picked up the Bergamo last year as it is sort of hybrid bike with the larger rims.
Thing is, it has one of the novel transmissions in that it has but one sprocket, so all the gearing is in the rear hub. Nifty item, but I have a couple of problems to iron out.
A. The tran emits a squeaking noise at low speed and,
B. Occasionally the shift is delayed.
Is this a lube only problem, and, if so, how does one lube the rear hub internals?
Otherwise, are there references on fine tuning the transmission? I tried Bianchi and got nothing.
