I took the Park Tool class last year and bought the necessary Big Blue Book. I also bought a few tools, including a cable cutter.
I had recently wrapped drop bars for the first time. It wasn't a great job, but it was functional. After a minor spill I managed to tweak my brake levers. I also wanted to adjust the hood position on the bars.
I bought cables, housing, and bar tape. I re-cabled the bike (easy two brakes, single-speed), and re-wrapped the bars. The brakes work great now. The hand position on the hoods is more comfortable, and I did a much better wrapping job than the first time.
Oh, and I went with pink.
I've been trying to do more of my own work. Although I'm a lousy mechanic, it's not that I can't get it done. It just takes me a while.
Now I need to buy some more stuff and completely re-cable my LHT. It's only got 5900 miles on it.
