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.
I ordered mail delivery of spare parts to Gomel a couple of times. Everything is fine. That's just that SMS spam from the store periodically comes with offers to take a test with them, and the promotions are different. Why would I do that if I live in Gomel?!
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!
