Epic Expert Carbon in medium about 25lbs out the box. Go tubless and new wheels you can knock a good pound off that. Some have got them in the 23lb bracket.
The stumpy hardtail is about 24lb, I chose the Epic as its a litlle more comfortable with some suspension.
The Stumpy FS completely different bike. Not sure of the weights but I rode them both and the Epic is rapid.
Found the Camber to be a confused bike. Nice but neither one thing or the other.
My Epic medium is OK for me and I am 6ft, specialized recommend a large but I felt too stretch on it so went for the medium and coudnt be happier, unless I could have afforded the S Works. I managed a 20% discount on a 2012 model from my lbs so ripped his arm off for the deal.
