[Bicycle] Bicycle rear derailleur pulleys cheaply replaced

There was a noise from the bicycle.
There was a broken back transmission.

 Even both were broken.

I ordered Aliexpress because the ride was not too bad right now.
The pulley can be driven to home even if the damage is serious.
I think I've been waiting a little more than two weeks.

Two pulleys were damaged.

The gold is brilliant.
It cost about two dollars.
It's about 20 percent of the price of the pure Sram products.



It's not as rotating as a ceramic bearing, but it's just as usable.
It's not a high speed drive unit, so I don't think there's a big problem.
