I get some grinding vibrations from rear wheel at speeds above 70km/h or at fast uphill driving. Is this normal?
Anything below 70km/h on a flat terrain is silent drive, but above, when aerodynamic resistance becomes so big or when going 60km/h uphill, I sense some grinding vibrations coming from the rear wheel.
I do understand, that the gears have to work harder, I just want to make sure that I'm not the only one.
Is it normal?
