My friendly tech just finished up.
It was Go-Go's hair fouling up the works.
No need for anything but pulling the hood, cleaning the exchange and thawing some ice... it was a mess.
We spent most of the time speaking about the multi generational succession of bicycle volunteers we have in our area and how much we enjoy riding on the many public facilities that are the result of that tradition.
I think he should have charged me more... I'll have to make it up to him by recommending him every chance I get.
best regards,
