What to bring on a 5-month bike trip?

A good question! The key thoughts are that I'll be traveling early spring in Ukraine and Russia - could go down to near freezing in the evenings! I'll be going across the Kazakh steppes nearly in summer, with temperatures up to 30C+. Kyrgyz mountains, with the possibility of frigid rain, require a little bit of warmer weather. Xinjiang in China is desert in places with super hot and dry weather. Overall, a bit of a planning challenge! To make it worse, spares and repairs are likely to be hard to come by, so I have to carry as much as I can!
