I just checked all my bolts, pulled the bars 3cm closer to my chest, rotated the bars down a little, pulled the brifters a little closer and rotated them more so I don't stab myself in the knees when I change gears, disconnected all the cables so I can rewire my V20 tomorrow, and will install new grip tape. All of those should make it a bit more comfortable, get my arms tucked in more, and should incorporate my back muscles instead of my biceps when pulling on the bars during heavy cranking.
I bought a 3.5" water bottle cage to hold a 1L bottle on the XLab cage in back. I drilled a hole in the cap for a make-shift straw because there isn't an adaptor for that size lid. While it held the bottle perfectly, hydration splashed out through the straw so I might have to concoct up something new with the bite down tube.
