I have slowly gotten my size Large Camber expert down to the high 26# range and I still have the stock seatpost, stem, and bars on it.
I just bought a pair of the new FEA design Specialized Fast Trak Control 2bliss model last night, they were 520g each on the scale +/- a coupe grams, about 100g each lighter than the Captain Controls I removed.
Like said earlier in the thread, wheels/tires are a big, you can knock a pound off the bike for a few hundred bucks pretty easily. I yanked my stock rims and put on some Mavic Crosstrails.
But for me, here in Texas, I only need a single chainring up front, I convert all my bikes to a 1x9 or 10 right when I get it, removing the front der, shifter, extra chain rings and going to a medium/short cage rear der and removing some links from the chain drops a pound or more pretty quickly and easily. I think on the Camber it dropped almost 2 pounds off the bike before I took it on the first ride.
The only things I want to do more to the Camber are stupid little things, new bar/stem/seatpost and the new Specialized XC lightweight grips. I'll likely go with carbon bar and seatpost and I'll probably pick up a pair of Alligator windcutters to replace the G3CS rotors and that should get the Camber in the low 25# range. This should be a good spot for your Fuel EX5 as well.
I don't know which fork your Fuel has but if its got a spring in it and weighs 4.5# or more you might consider upgrading to a used Reba thats dual air, I think the one that came on my Camber is about 3.3#.
