I have a Giant frame with a one inch integrated headset(threaded). I would like to upgrade to a Carbon fork and threadless headset. Does the fork have to be made for integrated headsets or will any 1 " carbon fork work? I've seen several at online retailers that have a 1 1/8" integrated carbon fork but none in one inch. I also found that Cane Creek makes a 1" integrated headset(hard to find) that I presume will work with my frame but I'm not sure. The Giant dealer in my area doesn't seem to know any more about this than I do so I'd really appreciate any help......
