Repair of school bicycles

Last time I wrote that the threading accuracy is bad, but the pedal side threading accuracy was also bad, so I got a pedal while driving. I am glad that there was no accident.
I attempted reinstallation, but I had a difficult time doing without inserting a pedal or burr treatment at thread cutting. I would like quality control before plating processing.
If it is said that price is suitable, it is until then.
Exchange of cranks on school bicycles

I think that the texture and precision are suitable for price. A good point is the price and the speed of appearance and delivery. The bad point is that the screw cutting accuracy on the BB side is bad and the entry of the crank pulling tool is bad. Rubbing the chain with guards may cause unusual noise. Iron crank has reasonable weight.
Ideal for changing the gear ratio

When I bought a small bicycle with a single speed of 20 inches, the gear was so heavy that I always stood on a climb, so I switched from the originally attached 48T crank to this 40T crank. It became a gear ratio of about ordinary mama Chari, and it became really comfortable. I chose black, but the finish is very beautiful. I think the gear guard is also solid and it does not seem to be a problem. The price is also cheap, the length of the arm can also be chosen, it is not bad as a practical item. Because the arm is iron, it is a bit heavier than the aluminum crank, but it is a general weight as an iron crank. Since the price may be slightly increased, it is better if there is a lightweight version of aluminum.
I replaced it with an old crank.

I bought it because there was only 40T's number of teeth with a good force application. The price is cheap and there is no problem on the function at all. If you want a greedy finish of shiny silver plating looked a little sloppy.

Although the number of teeth has decreased from 48 T, there is no problem. Texture is also nice.
