Bicycle wheel building : part 2 : installing left side trailing spokes

This video shows how I install the trailing spokes on the left side of the wheel for a 20”, 32 spoke, cross 3 wheel. The follow on videos will show how I install the remaining spokes and tune the wheel.

This wheel will be used on the ShortHopper electric bike. To see more about this project click on the ShortHopper Category.

This series is a great intro into wheel building. Thanks, Dan, I know it’s a lot of work to build, video, and narrate the process. I’m looking forward to the next episode.

Thanks! More videos are on the way. I wish I could put them out faster.

Great video!

How do you identify the correct hub hole for the first trailing spoke on the left-hand side?

On this rim the first trailing spoke on the left hand side will go between the key spoke and the valve hole because of the way the rim is drilled (the holes are angled to one side or the other).

Hubs are drilled such that the left and right side spoke holes are offset. Insert a spoke into a hub and you’ll see that it hits the other side of the hub and doesn’t line up with any of the holes on the other side.

So to answer your question, insert the first trailing spoke in a left hand side hub hole and see where it hits relative to the right hand side key spoke. It must be on the same side of the key spoke relative to the hole in the rim that the first left side trailing spoke will go. If it’s not, try the next hole until it is.

Let me know if this helped. It’s hard to explain with words. If it’s still not clear, I’ll explain it a different way or post a photo that might help.

I just signed up to your blogs rss feed. Will you post more on this subject?

Yes, I have all the video shot and I’m editing when I have time. Right now I’m working on Leah’s electric bike conversion project and will get back to the wheel building videos soon. Sorry for the delay.
