Wow, I'm happy I found this thread! I just got my frame and I'm building it up. I found that the rear of the frame is skinnier than it should be. I try to put my hub in (normal boost hub), and I have to pry the frame apart about a cm to get the hub in. Has anyone else had this issue? I don't think it is the end of the world, but I am a little worried that it will make the derailleur hanger a tad crooked.
