S4 (Quick tip, 6 seconds) is under the 10 second chapter minimum, so I merged it into S3, the segment before it. S3 + S4 now runs from 1:58 to 3:26.

Chapter list

Titles use words from each segment's notes. "true a bike wheel" appears only in the S1 notes, so only the first title carries it.

Whether YouTube shows chapters on this video also depends on things not in your input (for example active strikes on the channel). I cannot check that from here.

Outline

  • 00:00 How to true a bike wheel at home: "what a wobble looks like at the brake pads".
  • 00:41 Tools: "truing stand or the bike frame, spoke wrench, a zip tie as a gauge".
  • 01:58 Finding the wobble and comparing spoke tension: "spin the wheel slowly and mark the high spot with tape", then "pluck spokes to compare tension".
  • 03:26 Side to side truing: "tighten and loosen spokes in quarter turns".
  • 07:45 Fixing a hop: "up and down truing on the high spot".
  • 10:12 Dish check: "is the rim centered between the axle ends".
  • 12:05 Final spin and test ride: "Final spin and a short test ride".
  • 13:40 Outro: "next video is replacing a broken spoke".

Questions for you

  1. Is the merge right, or should the plucking tip join S5 (side to side truing) instead?
  2. Should the outro chapter name the next video's title once it is live, or stay as written?
