Replacing the bicycle derailleur and change the gear cable. Bike chain lubrication

Hello, fellow cyclist. We have a children's bike with a bent rear derailleur brought to our workshop. Children's bikes in most cases need the same maintenance as bikes. Children may not be very careful with their bikes, throw them, fall, which leads to premature failure of bike parts. In this video, I will show you how to replace the rear derailleur of a bicycle, adjust it, replace the shift cable and lubricate the chain. The owner of the bike will be able to ride his bike again with pleasure. I hope you enjoy this video. Have fun watching it!
