Hello,
Recently I bought a very cheap mountain bike. I want to clean and repair it so I can ride it.
Started with some basic cleaning and escalated a bit..
Took off the chain to clean it properly.
Changed the outer and inner tires.
Took off the cassette and cleaned it.
Changed the bearing balls of the rear wheel because the wheel was wobbling from the axle.
Dismantled the derailleur to clean it.
Now the rear wheel doesn't spin for long on its own. I look up closely and it does not touch the frame or brake pads anywhere so it cannot be that. I wondering what could the issue be. I have attached a video.
The wheels on the derailleur are wobbly and that's how they were from the very beginning. Is that fixable? Or do I need to buy new derailleur? Or maybe buy a whole new bike 🤔😁
