hey erick, sorry about the delayed reply:
i had to file the bit of welding on the inside of the frame where the bearing holders are welded to the frame. it took about 30-45 minutes of trial and error.
Hey, I read one of your posts saying that you had to file you addict frame to fit your nimbus hub. I just want to ask what part of the frame and how much you had to file bc I want to get an addict gravity frame and I'm not sure how it will work on my nimbus hub.
