I also keep asking myself why did I buy it! .)
A person from next village was selling it as a pub bike pretty cheap (and dirty and with most parts exchanged), and I thought I will just grab it and see what parts are usable, as I might even have use for the fork it has in case I trash the frame. Since that I'm just walking around it and thinking whether it is safe to commute on it, as I like the paint scheme and generally would prefer not to throw usable frame away.
Well seems opinions are a bit split and it is true I am not really confident, I'm inclined to not try how long it might last.
Thank you everyone for helping me to sort it in my head kind of .)
