koosk, My distance road bike is black (10% gold metalflake in clearcoat) and I went mostly black WRT stem,handle bars, saddle, bar tape and seatpost. It looks good to me as I'm not too big with 'shiney stuff', but I've seen black bikes with bright stems and seatposts with tan colored saddles and bar tape that were quite classy.

For brakes I suggest a set of Tektro 'V-brakes' and matching levers. These don't require any extra devices like a travel agent. I also suggest mountain bike derailleurs, rear cassette and crankset... shifters can be down tube or bar end, I prefer the latter for a touring bike.

Hve fun with the build.
