Hello, I just purchased an orbea track frame and it did not come with a headset. Much to my dismay, with this being my first foray into the world of integrated headsets, I recently found out that all integrated headsets are NOT interchangable. Browsing both Orbea websites (Spanish and US) did me vey little good (I only confirmed that it is in fact an integrated headset. . . big whoop). SOOOO, what I would like to know is whether or not anyone out there has any clue as to what what kind of headsets will work with my frame. I'd like the Chris King Perdido to work, but if it involves reaming the headtube I have now I'd much rather not (though I can be persuaded to do so if anyone out feels that it is leap and bounds better than either the FSA, Cane Creek, or Campy oferings). Thanks in advance for all of your help.

check out the parktool website, they have pictures and measurements of all the different headsets. If that fails call orbea or ask your dealer?

Good Luck

According to Orbea's website (www.orbea.com) they come with FSA headsets as standard, but I had one a couple of years ago and I seem to remember it had a Cane Creek. Now I could be wrong or those two could be the same spec, but if you stick with FSA you'll be fine (unless it's an older frame and they changed the spec at some point, which I doubt).
