I had one, then my parents quickly saw that one is not enough
I was given a few more sets. They weren't thematic like that ferris wheel, but still had axles and stuff. I built a car that had the doors open... Also a revolver with a revolving drum because it was still VHS Era and I had seen the dollars trilogy 20 times and I read Karl May novels.
I found black headset cups in an old frame, but I didn't like them so I will leave the chrome cup finishing the shifter. It also turns out that the cup I used is 1" BMX and not 1 1/8" as I thought.
Anyway, I had noticed that pedaling hard pulls the axle in the dropouts and the wheel almost touches the left chainstays. I disassembled the rear, swapped the 16t rear sprocket for a 19t and pushed the wheel forward to the end of the dropout slots. I think it became a bit quieter too which makes sense since it should also improve the chainline - less angle from the rear sprocket to the BB, also the chain is better wrapped around the sprocket.
I am curious how will it ride, considering that I could go up to 23t. Unfortunately it is raining every ten minutes so I don't know if I could take it for a ride today. I am thrilled to test the shifter which should make all the difference.
