In general, a good bike shop + workshop, but you can get into not the most friendly mechanics. There was also a case that after I took the wheel with the replaced bushing, I discovered that during the replacement they had lost the nut and spring, which were thrown on the axle from the opposite side of the eccentric. Unfortunately, I only discovered this at home (I didn't pay attention when accepting the wheels). But fortunately, we managed to solve the problem by installing the nut and spring from the axle from the old bushing.
A normal bike shop. Everyone who is interested in bicycles knows about it. There is always a lot of stuff available, which is very convenient. I can't say anything about the workshop, I used it once sooooo long ago.
I liked everything very much. The guys held a consultation on Viber, recommended how to get out of my situation. Thank you so much for your prompt work!
