Most recently:
- Cracked dork disc. Threw it away. One problem solved.
- Thicker stainless spokes on new wheel rubbing. Not gonna worry about it for awhile, maybe it'll wear in.
- Nub of rear brake cable repeatedly flapped by my heel, snapping against the frame. Tucked nub in behind caliper.
Soon as I fix these, some other dumb noise will appear.
