Re: chain rubbing chainstay
When I said I was speaking from experience, I was talking about my first build. The motor chain was close to the chain stay but it was not touching it, until I was riding down the road. Then it would occasionally touch the stay. Ended up getting a hole in the stay and had to trash that frame.
Trust me this is not something you was to put off.
