Sometimes I really wish a could transform myself into a mouse - this way one might be able to collect serious data…
The reseller should at least be able to change the drive as a whole for my meaning.
(And if it is a good reseller he has to have a few replacement drives in stock.)
That should be possible, the costs are most likely lower than that of an ATS (dual) speed drive kit ( ~ 500 $).
I’d expect ~ 300 US$.
Edit:
One year riding 50 kms per week are in sum about 2500 kms - right?
I’d say; of course is that speculation only:
If your drive would be affected - it would be broken already a while ago.
