Wheel dropouts for builds can come from a variety of sources. Often the dropouts are hacked from the frame of donor bike from whence the wheels came. However, as can be seen in the photos of the forks, those dropouts are offset in an angle. I need straight dropouts for the pedicab, so those wouldn’t do. Next I looked through my stockpile of donor bikes for two identical sets of dropouts (the pedicab has two wheels after all).
