I am looking at getting a Chris King NoThreadSet for my Specialized Allez Sport. I have e-mailed Specialized and they tell me that international frame manufacturers have gone to a 34.0mm head tube diameter. They go on to say that this means that I have to custom order an oversized headset from King.(They kept their cups at 33.9mm) Supposedly you must do this directly from King because they don't sell them to local suppliers. Does anyone have experience with this? I am trying to avoid ordering the wrong parts and I don't have a set of calipers to measure my frame with.
