Really nice bike. Are you sure about need of barends? I had a 29er ht testbike for 1 week with a 680 mm bar which was very comfortable and will also use the same setup.
9.2 kg? is that not a mistake?
I have a 2012 sworks epic with a tune seatpost, very light saddle, the same pedals and 8g grips and the bike is 10.05kg (size L). is this possible that your bike is full 850g lighter?
I have the same tires as he does, tubeless, the frame size is minor weight saving as well as the front derailleur is maybe what, 200 grams? Titanium bolts are meaningless, still far from 850g difference
Fair points, and agreed the Ti bolts amount to maybe 20g across the whole bike.
He also loses the small chainring and shifter (and cable) though. Assuming you're running XTR with i-Spec, that's another 95-100g and whatever the small XTR chainring amounts to.
my bike is sram xx not xtr,
I checked the weights online,
front derailleur from sram xx is 112g
shifter is 92g
cables probably around 20g
the sram xx double chainring for spec is 178g, one of the biggest chainrings for XX1 is 58g (34 tooth), this is a saving of 120g (major!!!)
so total weight advantage of xx1 would be around 344g, still far from 850g weight difference.
I weighted my bike on a park tool hanging scale

You missed a few things.
XX double @ 178 includes the spider, but 58g for a 34t does not include the spider.
XX1 Cassette/freehub is 50g heavier and rear derailleur is 60g heavier.
@madhead: 9.2 is realistic. My 2011 26" Epic was at 8.9 kg. If you change over to 29" only the wheels incl. tyres are heavier. So 9.2 kg is ok. Please post a detailed list of components then we can tell you the reason for weight differences.
@PanuV: looks like you can use a straight seatpost. Also it would be lighter than your current one. And please add a partlist including weights, ok?
First of all sorry not couldn´t answer earlier, a busy, busy busy week in work…
You guys are absolutely right. She does not weight 9.2. Kg! I made measurements in a terrible hurry with my old fish scale (didn´t even own any digital one... I prefer training & racing, not having any partlist with weights, sorry)
The feedback bothered me so badly that I went last evening to hardware store and buy a new digital scale… The result? 9.39kg. So, she is chubby…
My deepest apologies I gave you invalid information! That was not intention.
Mine without pedals is 8.920 kg is 2012 originally it was shimano, now is XX1, carbon ti integrated chainring, mcfk seatpost and handlebar, extralite titanium bolts, magura mt8 brakes with formula 160 mm rotors, aluminium m6 bolts, tubless setup, syntace x12, and carbon ti qr

I had a Extralite Ultrastem OC stem on my Epic for a bit. What I was finding is that with "wide" 660mm bars the Extralite stem was flexing quite a lot under load, such as when climbing uphill. It was ok when I had 580mm handlebars but with the added leverage of the wider handlebar the stem was visibly moving. The ends of the handlebars would rock up and down in time.
I switched the stem out for a Ritchey WCS260 carbonmatrix stem. It's a few grams heavier (Extralite Ultrastem OC 100mm claimed weight 85g, Ritchey WCS260 carbonmatrix stem 100mm claimed weight 115g) but the Ritchey stem does come with steel bolts which could be replaced with titanium to lighten it more.
The stiffer stem gives a noticeably stiffer handlebar to lever against with your upper body when climbing. I'd say it maybe also helps a little with cornering also. For the small weight gain I felt it was a worthwhile improvement to have.
