Edited Date/Time:
I have the fly dolmen cranks and i just bought a 25T tree lite sprocket only to find that the drive bolt hole on the sprocket is too small and the drive bolt won't fit. Has anyone ever seen something like this before? Seems really weird to me. What should I do (try to mill it out a little, return in, get a different sprocket)? lol
