LOL. Is frame-building not something you learn by finding an old BMX frame, and adding bits to it, when you are a teenager, then slowly progressing up to joining, lathing, designing, etc?
Call me old fashioned...
Your example is literally a romanticised version of what I wrote
I did notice they demand potential mechanic students to purchase one of several bikes. WTF is that!??
Sounds like pretty standard practice in Japan. Like my local LBS who said
1) I can't ride with/join their team
2) I can't get any maintenance done.
3) they won't order a power meter for me
Unless I bought a bike from them. Its kind of a running joke now. I keep asking and they keep telling me I need to buy abike from them.
