the bearing cups that came on it were showing outside of the headtube. it had no headset just frame with forks hanging by the derailleur and brake lines. I can try to get pictures up later tonight when I get home. But I did do some measurements this morning.Look at the bearing cups, are they outside of the head tube or internal? ZS44 generally has minimal cup showing, typically a lip where as the standard 1 1/8 have approx. a 1/2" of cup showing above the head tube. This is just a generalization based on what I have seen. If you can post a photo we may be able to tell.
