I just weighed both of my bikes - the 2018 Specialized Crosstrail Sport - medium frame - with the brain fork came in at 30.8lbs with the spare tube and flat repair kit installed under the seat. My Trek 7.2FX came in at 30lbs (it does have added bar ends that I put on to help alleviate hand numbness). They'd be pretty much dead even if I removed the Crosstrail extras that I moved over from the 7.2FX(tail light, bottle holder, under seat kit).
I had the impression during my maiden voyage Sunday on the Crosstrail that there was no difference in the weight between the 2 bikes and it looks like that was correct.
