    Giant OCR HS, fork and stem

    I bought an OCR1 last spring for nasty weather riding and at the time really didn't pay attention to, or much care about, a few of its funky components. I took my wrenches to it this week looking to replace that 3/4lb (literally) adjustable stem and discovered it has also has a threaded fork (1"). Aside from the threaded issue, the fork is cut too short to use with a regular stem anyway.

    My assumption is that in order to replace the stem I also need to replace the fork, but could use the factory installed integrated HS. Could someone confirm this, or educate me otherwise...Thanks.

    I have a 2002 Giant OCR-3 with a "funky" stem and a 1" threaded fork. I replaced the fork with a used Time Equipe Pro carbon fork that was the exact same length with the same length of threads (got lucky). I stuck with the threaded headset and replaced the adjustable stem with a stem converter so I could put a Giant Carbon stem on the bike.

    My understanding (from Rev. Chuck) is that the Cane Creek ZS-2 (zero stack) is the only headset that fits if you're looking to convert to threadless.

    The newest versions of the OCR have changed again with a company called "VP" supplying a headset for Cane Creek. I believe it's the VP components company but it appears that Giant has changed the dimensions on the head tube so I'm not sure if there's any retro fit.

    If you hear any differently from Giant (if you can actually find a customer assistance link), let me know because I'd like to look at a threadless version in the future depending on how the carbon fork goes.

    BTW, since you're fork is already carbon (I think) you should be able to just use a stem converter and a regular stem.
