Does anybody know the headset size on a cannondale caad 1 frame?

Also was there any problems with these frames?

Thanks

1 1/8 inch

Should be a 1 1/8 inch standard if it is truely a CAAD 1. Frame is fine, was Cannondale's "cheap" frame. No special butting or tapering here, just strait guage aluminium. Probably will beat you to death off road as these older frames were STIFF.
