X2 & X4 are 31.8
The Elite is 25.4 & 26.0
EDIT: X2 and X4 actually I think are the almost same other than the angles they come in and the 2 vs. 4 bolt faceplate. X2 comes in 10 & 17 degree and the X4 in 0 & 10. Maybe some slight machining differences too, hard to tell.
OP: If the stem gets your fit right, don't worry about it - you've got a quality piece of equipment there.
