I have a new Giant Glory FR 0, I have developed a creak, at first I thought it was the fork, now I am thinking headset. I has an FSA Big Fat Pig 1.5. I have re-greased it, it sounds like the creak is coming from the lower cup area. I have read that these headsets are tough, but the seals suck and all the grease works its way out in a few rides. I am thinking of upgrading but am trying to exhaust all the possibilities before I start replacing things. Any ideas?
