    Default Headset lower stack height

    So on the Lemond I just picked up there is a Cane Creek headset. Just making a quick measurement, not even with a calipers, there looks to be a difference in stack height between the Cane Creek and the Chris King on my Merckx. My plan had been to simply swap headsets to the King. Now I'm not so sure.

    I do not wish to screw around with the geometry on the Lemond but I think the Cane Creek headset is pretty damn ugly. Possibly even fugly.

    Anyone know the lower race/cup/bearing stack heights of Cane Creek vs King? Anyone know if this even matters? (it must....) But I see Richard Sachs bicycles with Cane Creek and some with Kings.

    What's the deal? I don't mind buying the fancy schmancy Cane Creek headset if it'll keep the geometry proper.

    BTW, I am sure the existing Cane Creek is just fine functionally. But if life was only about function, there wouldn't be a big debate about head badges.....

    i'd start with a horse sized pill and work my way down to the small ones. stop at the one when you still know who you are, but aren't worried about this shit.

    I know, but different tires are installed front and rear.

    The horse pills only get taken as hangover relief.

    I'll probably leave the fugly cane creek. It works.

    You'd probably have the same discrepency with a used/boxed rear tire and a fresh front one. Bet you wouldn't notice the difference. Wouldn't worry about it.

    Sounds good, in theory, but if we didn't analyze this stuff this board would too quiet.

    With manufacturers specifying .25 degree differences in STA's, and .1degree increments in hta's, I can understand the question.
    I'm just not sure i can tell a feel a difference in the answers; but that's besides the point.

    Take a King headset apart and you will notice that the design of the whole thing is contingent upon a $0.002 o-ring (which they sell for $6.) On the other hand, Sachs has been banging Cane Creek headsets on all sorts of tough cross circuits for years and they seem to hold just fine. I have a Cane Creek headset on my Sachs cross bike and I have no complaints. I'd love to get rid of all my King headsets.

    Probably the reason manufacturers don't spec a particular headset: the difference in stack height is negligible.

    spec'ing in print and variances in the final product are two different things.
    hell, half the guys i ride behind rear stays aren't even aligned.
    we are in the domain of good enough.

    next time you're riding with a group... look at the guy's bike in front of you and try and see if you can see the mis-alignment.

    Likewise, I bet the axle to crown on most aftermarket forks is within a 2 or 3 millimeter variance. So now you have to find the right headset for the right fork for the right frame. Or you can just ride your bike. :D

    I know. It's about Lance. But we're over that. He didn't win this year.

    Anyway, being anal retentive and detail oriented are why the great ones are the great ones.

    Just trying to be detail oriented.

    Anyway, I think the Cane Creek'll stay on. It's what the bike was designed with.

    Worrying about stack on an Asian bike built in batches by the hundreds for $50 each is MP. Go with what you got.

    And if you just have to ...

    isn't CK coming out with a lower stack option?

    no one designs a frame around a lower headset stack height.
    unless they're rigid, that is atmo.
    the variations in modern dimensions that apply to the frame type at issue are too small to matter.

    Got it. Here's what'll stay on.



    BTW, the bike is not Asian made. It's made in the US (in Wisconsin IIRC, by Waterford) of US tubing. Not that it really matters if it's Asian made, but it does to me, for reasons that are complicated and not worthy of discussion here.

    But....

    With all this said that a few millimeters of this don't matter, can someone answer why? It does affect rake, trail, front-center, etc. We hear all the time about how these numbers create the Gestalt of a frameset. Why is my question regarding something that differs by as much as 5 millimeters not worthy of discussion?

    BTW, no discussion needed.

    I take e-Richie's answer as being good enough. Seriously. He knows. I don't.

    Just thought the differences might matter.

    Only reason it'd matter is if you couldn't get low enough with the extra stack.

    Shouldn't be an issue for most but I know a few people who've had to get different top caps to accommodate their fit.
