    Headset Issue

    So apparently aheadset's zerostack headset didn't fit on my 727tr headtube . The thing looked like it fit , but it wasn't going down all the way . Here's the specs of the aheadsets's Zerostack Headset:
    (link:http://www.aheadset.com/bicycle-headsets?p=ZS)
    ____________
    size 1 1/8"
    material Steel
    race 30.0mm
    cup 44.0mm
    bearing 5/32 Ball
    top stack height 10mm
    bottom stack height 4.5mm

    So to my understanding another website is stating that FSA's ZS3 headset is the only headset that will suite the 725/727tr frames. Here is it's specs:
    (link:http://www.iminusd.bigcartel.com/pro...on-zs3-headset)
    ____________
    TH brand 36/45 degree Micro Angular Contact Bearings (blue seal)
    7075 aluminum crown race
    Laser etched FSA aluminum top cap
    Stack Height* - 9.8 + 3.3 = 13.1mm
    Black anodized finish
    Weight - 80 grams (1 1/8")

    Now can anybody help me ? I just wanna start ridinggggg . Thanks !

    The Aheadset ZS cups are too deep and will bottom out before becoming flush. You need to use an FSA ZS3 or something with shallower cups. Leader recommends that particular headset for a reason.

    Besides, the Aheadset is junk.

    This is what I used >>> http://www.universalcycles.com/shopp...5&category=724 It may be a bit cheaper than the FSA.

    Ideally... especially with sealed headsets in this case, where you risk ruining the bearings if using other unconventional means...

    Stack height is by personal preference; although having it too high and slammed (virtually no stack, just stem) is looked down upon.

    The 727 and 725 are siblings minus cosmetics.
