    I hate you, head tube
    so i have been searching for a couple of days now, tried seeing if i could call the manufac., and went to a couple of bike shops to see what size headset fits my orbea sport frame. I am getting so frustrated with the fact that no one can help me and I just want to ride my bike. Does anyone here know about orbea bikes? please lend a helping hand...

    You could dismantle the bike, removing fork and bars, to remove the headset.
    Its not a time consuming job and you have to do this anyway to fit a replacement headset.
    If you cannot get the info you are looking for, what option do you have?
    This is a Framebuilding Forum, having knowledge of frame construction, not what is coming out of factories and can advise on there many models. This is a question for a LBS who sells your bike.

    There's basicly 4 that fits. 1 1/8 standard, 1 1/8 inset/zerostack, 1.5 oversize, 1 1/8 top with 1.5 bottom tapered.
    Just by glancing at their prebuilt bikes, it looks to be 1 1/8 inset/zerostack.

    Do they not list anything on the Orbea website stating what kind of headset the frame uses?

    Going Here:

    I see that the 2012 G10 uses a 1 1/8 semi-integrated, which would then allow me to purchase the correct Cane Creek headset.

    You haven't listed what frame you have, etc. You should also look on their website to find a local dealer, who should be able to give you advice also.

    For intents and purpose the measurements are roughly:
    ~1.75 = 44mm = 1 1/8 zerostack
    2in = ~50mm

    1 1/8 zerostack is for a 1 1/8 fork, but the whole cup/bearing sits inside the head tube.

    Check out the Zero Stack or "Low Profile" section.

    All my frame says is that it's an orbea sport...so I will prolly be needing a semi integrated 44mm...
