A well-known and well regarded shop fixed something on my converted single-speed bicycle. On the ride back from the shop, the pedaling felt "different", and I noticed that the pedals will stop after less than a turn when pedaling backwards.
I went back and the mechanic explained that he overtightens the rear wheel in the dropouts. In his experience, within a few days the chain will be back to normal and it'll be fine.
However I wonder if this could cause issues of wear and tear and ruin other, perfectly working, parts?
