Replacing the drivetrain on a mountain bike. Servicing your bicycle in the workshop

Hello to those who like to maintain their bikes :)
This is a cool video tutorial where I will show you how to change the drivetrain on your favorite mountain bike.
This bike came into our workshop for service and parts.
You will see the full range of work that was done. First, we disassemble the bike so we can thoroughly wash the frame. Then we'll start reassembling everything in reverse order, but using new bicycle drivetrain parts.
After such a complex of technical work and replacement of consumables, your favorite bike will get a second life!
Your bike will please you again, just like in the first days after you bought it!
Enjoy watching, dear viewers!
