Into the great wide open

The donor bike is a 2016ish CAAD10 Ultegra with Kinlin XR31 wheels, so it will be upper-ish but not too fancy I suppose.

Shopping list:

• Fork: The search continues. I feel like I'm digging deep into audax bike history to try to even come up with suitable model names. Have had to use the Internet Wayback Machine more than once.
  
• Brakes: Shimano BR-R650s are meant to be the best of the best, when it comes clearance and stopping power. They're far less accessible than the much cheaper and similar R451s, but this bike will be used in hilly terrain so I'm keen to invest in the brakes.
  
• Bottom bracket: finally I can be free of BB30. Don't know anything about BBs so I'm assuming I can just get a standard BSA Shimano one for cheap. Will probably need to buy a special tool too.
  
• Chain set: Thinking Ultegra here. The groupset is 6800, and as I've seen from @ojwithbits recent FS thread there are some exciting combustion features on the 6800 cranks. Not sure if I can find some un-recalled ones. Will be going compact. Have no idea about crank lengths.
  
• Tyres: haven't actually thought too much about these, aside from wanting them to be wide. The CAAD has 25s and even run tubeless at low pressures was a very uncomfortable ride on the rural roads it found itself on. Kind of curious about the Jack Brown Mile Munchers in 30 mm. Failing that, have always been a fan of Conti 4 Seasons. Maybe these tyres are overly robust for country roads where the chances of a puncture are pretty low in my experience.
  
• Cables and outers: always been too scared to try any of this stuff but am going to have to face that fear.
