Then as I spun the cranks around, I noticed that my chain loosened and tightened in an oscillating pattern. I’ve then discovered that these holes aren’t perfectly aligned. This made chain tensioning a big confusing headache and only today after a week have I found the answer to all this confusion. Everything else worked fine, but…
