Everything is simple when you know what you're doing.
When you don't know anything about bike mechanics, rocket science might seem easier. I know it did to me.
I think this thread is less about the mechanics and technicals, and more about the spirit of building a bike,
Personally, I think just about everyone can do it. I also think everyone
should do it - at least once.
But not everyone thinks they can do it.
Hopefully Serge has shown those people that the right attitude and spirit will compensate for the initial lack of knowledge.
No disrespect intended, but a bit of inspiration is, well, more ...... inspiring than being told it's not rocket science.
I'll leave the last word to the Master
