That's a lot of stuff. Wow.
I'm thinking about what it would mean to try to carry all that on my bike. It may be worth swapping the racks and panniers for a decent trailer. A Burley will give you a lot of carrying capacity.
The list of parts has me a bit concerned. Is it really necessary? Perhaps it depends on the route, but there are a lot of populated areas along the way from China to Turkey. Would it be possible to get to the nearest town of decent size and get the required parts for repair from the bike shop or through the mail? I don't know the bike culture along the proposed route, so maybe each spare part truly is necessary.
I'm also wondering why two pots and a frying pan? Why not one pot and an optional frying pan?
The electronics could be streamlined too.
Still, every one of us has a unique touring style. Mine isn't what someone else would prefer.
