Good news, I was able to go and visit my girlfriend in lovely Buenos Aires, so more money can be spent on this little beauty.
So 1x10, opinions on which narrow wide to go for, my 36t I mentioned before was a race face one, but I'm tempted by Hope, or works components (made in the UK) and still need to finalise a chainring size, I feel like 34t is manageable, if not it's only £30-£40 to get the 32t and it's easy enough to swap. Was also looking at getting the XTR right hand shifter, not a huge weight saving, but will make those shifts as crisp as possible.
Any other weight saving suggestions? How do people feel about lightweight rotors affecting brake performance?

I'm now running 1x10, and think I've saved somewhere in the region of 380g, about 150g for the mech, 150g for the shifter, 50g for the chainrings and 30 for the switch from XT to XTR shifter.

So it's running a 34T E.thirteen narrow wide chainring in the stealthy black to keep in style with the rest of the bike :) Hopefully very close, if not slightly under 10kgs now! SO WW's what's next? (I will change the pedals from XT to XTR to save another 30-40g too.

Lighter tires. The Nobby Nic isn't an XC tire, which is why it's so heavy. I'd go for Rocket Rons instead.

The Reba fork must be quite heavy, maybe look at getting a SID or even a Lefty is price is no issue. The cassette is probably another area to save weight, SRAM cassettes are considerably lighter but don't offer the same level of durability. Maybe change the rear Nobbly Nic for a Rocket Ron or Racing Ralph?

I think you're at the point with your bike in which you'll start spending good chunks of money for not much gain. If that's ok with you I'd get a new brakes, XT are great but the new M987 XTR brakes are considerably lighter, or maybe Formula R1 or the post 2013 Avids which are much improved. You could also get some SRAM carbon cranks with an AbsoluteBlack spiderless ring to save more weight. Additionally replace all the bolts on the bike for lighter ones (stem, rotors, seatpost etc.) There are UNO stems on eBay that are around 90g and are cheap. You could also get a lighter handlebar (Mount Zoom) and seatpost (KCNC). Also forget the XTR pedals, Xpedos are way lighter and are still SPD compatible.

Yeah, I think tyres will be a good way to go, I fitted the Nics to get through the awful winter that was incredibly muddy here. I was also thinking of holding out for the 2015 XTR m9000 brakes as I think they look so nice, so unless I can find some m987s going cheap I'll hold out for those. The cranks were something I'm looking into, but it's a cost thing, I am just a student after all. The only reason for switching to the XTR pedals is that I already have them on a different bike so it's just a free weight saving :)

Hoping to get the bike weighed some point this week just to see where I'm at, and if I'm under the 10kg mark I'd be fairly happy to save up for some bigger items like a fork or crank :)

I picked up the Aishima Ai2 rotors (180/160). I think they saved about 80 grams compared to the XT RT-86 rotors I had.

Honestly...they do not brake nearly as well as the XT rotors...and they make a bit of noise. I wouldn't run them on an all mountain or downhill bike...but they are fine for XC riding.

I recently switched from the ESI chunky (54gr) to the Lizard Skins DSP (16gr) grips...while not as comfortable as the ESI...the Lizard Skins are lighter.

Nobby Nics are shitty mud tires IMO, I don't understand why people use them for that. They are also heavy (Nobby Nics 26x2.25 are listed at 545 g, while same size Rocket Rons are listed at 465 g). If you need mud tires look at the Dirty Dan. In my experience, Rocket Ron is better than Nobby Nic in mud. YMMV.

Hey, nice bike. How do you like the 27.5 wheels? I'm leaning towards the 29r version, but curious about 27.5. Guessing from the XL frame size you're a pretty big guy, why did you go with 27.5?

Hi, I'm about 6'2 and 75-78kgs (on the heavier side of that ATM!) But I'm just quite long, fairly long legs and very long arms which is why I needed the XL.

Think I will get some rons, or maybe a RoRo/RaRa F/R. Need to start entering some more races! The bike has been weighed, at 9.9kgs on the nose. Without bottle cages, but with pedals. XT pedals not XTR pedals. XTR are a 34g saving. So take that off and add on a elite custom cage and you're back to 9.9! Also with rotors, I am looking at the Quaxar Axim Floating rotors at 70g for the 160mm and I think they look pretty smart too. http://www.xcracer.com/shop/viewproduct ... ductid=299

As for the wheel sizing, I test rode both a 650B and 29er, A specialised Carve (L) and the Giant in both a L and XL frame size. Whilst the 29er was brilliant fun, and I will try and build up a cheap 29er as my next bike just for fooling around on because it was great. However I felt very high up! And the bike is so long, I forever kept thinking I was going to clip the rear wheel on obstacles. So for a lot of my recreational riding and winter riding a 29er would've been the way to go, however on the race course the 650B made perfect sense for me with quicker steering and acceleration. Hope this helps!

Thanks for that. The little bit of time I've spent on 29rs they have that "too high" feeling, plus we climb a lot here, sustained steep-ish climbs where momentum comes and goes and once you lose momentum with 29rs they kind of suck, at least it seems to me. But I have not had a chance to ride a light hardtail 29r, I think that might be better, especially once you get used to it. I've only ridden one 27.5, a Jamis XCT Team, and it was awesome, but it was a short ride and no way can I spend $6k on a bike (Note to self: don't demo any more super expensive bikes). I plan to spend as much time as I can this summer borrowing/demoing both 29 and 27.5. Really glad to hear your feedback.
