Surface cleaning of bicycle gears. Bike maintenance

Hello, fellow cyclists on our workshop channel. A bike was brought to our workshop with a not-so-clean drivetrain and a bent rear derailleur leg. In this video, I will show you how to clean the bike's transmission with partial disassembly of the bike itself. This maintenance does not require many special tools and can be done even at home. We will also align the foot of the bike derailleur so the bike owner does not have to spend extra money. I hope you will find this video interesting and informative. Have a nice day and enjoy the video!
