No, it is not the same geometry. It has exactly the same geometry in the values they show: angles, top tube lenght, head tube length. but chainstays are longer in the fxe, you can notice it in just any photo. The fxe is designed to give space for a mudguard. The pre cursa has no space for mudguard.
Precursa have space for mudguard, mine does at least, it even got the mudguard mount on the track end.
whether it's a little longer or not, it's still derived from the Precursa, if you're worried about the chainstay, just slam the wheel into the track end.
