Honestly, the fenders are the biggest puzzle for me. Most of the other problems I can fix by replacing black parts with silver parts, but there don't seem to be a lot of choices in fenders for skinny 26" tires, and with the 26x1.25 tires the frame mounting points are quite a distance from the tire.
One of the other fun things about this build was that I had to use every spacer in my parts drawer to cover that expansive steerer -- 11 of them on there. Of course, it seems like cutting the steerer on an LHT is sacrilege and I'm liking the high bar position.
