So I recently built up my bike and everything was running nice and quiet but now there seems to be a noise that I cannot find. My chain line is as straight so I don't think it could be that (although it does sound like it). It sounds like it is coming from the front of the bike, it is a slight rattling. The only thing I can think of is that I didn't grease the fork when I put it on so could that be it? (Although it started out making no noise at all. This is really bugging me, anyone have any ideas as to what it could be?
