달밤에 픽시 자전거 수리! (코그와 락링 분해 후 결합하기)

Hello. This is Silver Star Father. I recently upgraded my son's fixed-gear bike. I replaced the stock Cabeza Melin wheels with Velocidad A42 B2 wheels! While working on it, I decided to make a video showing how to disassemble the cog and lock ring and attach them to the new wheels, so I spontaneously created this video haha. It was even more meaningful because I did this work with my teenage son. It might be a bit rough, but please enjoy watching. Thank you :)
