all the above is possible..
the cobalt wheels aren't exactly the lightest. your drivetrain is a top performer so upgrading that would be spendy and possibly not shift as well. but a rotor crank and rotor rings would be a hair lighter and give a tap more performance i think.

id personally change the saddle, post, stem and bars.

the Thompson is pretty heavy at around 200g you can get around half that but they get pricy. mcfk probubly offers the best uberlight for the price. if not the kcnc is always a good alternative.

saddle's can get down to 50g.. yours is arround 250g i think. a selle italia can be 140g or you can get a carbon one from smud thats 69g and $129

that stem is probubly between 160-180g, kcnc offers a few that are good for the price there are plenty of sub 100g stems.

and for bars mcfk offers every shape and size all are sub 100g i think. if not kcnc has a cheaper alternative.

in all you can drop a pound with all those. which will cost about the same as wheels would to loose about the same amount of weight.

anything with tubless compatability.
a descent stans rim with stiff spokes(cx rays are popular) and hubs are up to you.
the cobalts have three styles now 1690g(think this is the older one) 1500g or 1380g(carbon version)

do some research see what you like. there are a lot of hubs out there

I have a Mojo SL built to 22.65 lbs. with a 150mm fork, wide riser handlebar, wide grippy tires, and the not so light Cobalt wheels @ 1520 grams, their skewers are another 125 grams.I'm in the process of having fairwheelbikes.com build me a wheelset = Extralite blue hubs, Sapim CX-Ray spokes, Sapim Alum. nipples blue, Enve carbon UST rims with fairwheels custom blue Enve rim decals.Depending on tires, this should get my bike into the high 21 lbs. range.
Like faceless said, change the bars, stem, seatpost,seat. Start with the stem - get the Ibis stem & 6 Ti bolts for it from torontocycles.com, its dirt cheap to buy and very strong as Ibis specs this stem on the AM HD Mojo. My 70mm is 91 grams & I have an 80mm at 93 grams.Next would be a Schmolke TLO riser bar,685mm = 100 grams.
One of the best upgrades I did to mine was the Specialized S-Works carbon cranks, Lighning spider and Extralite chain rings. Its a very slick set up, much lighter than XX and shifting is great.I have a thread on the Ibis forum on how to make these work on the Ibis.They are also dirt cheap if you live in the USA - $300.00, super stiff with no weight limit.I'll try and post a build list later.

Its Alligator I-Links cable. Very light & its fully enclosed from the shifter to the derailleur - great for keeping dirt & water out.Shifting is excellent. I run XTR inner wire cable in it.Don't get the mini I-Links, some have issues getting it set up, although its even lighter than the regular I-Links.

I weigh about 165lbs.. on my fat mode atm and yes I am doing light xc, I am really focused on getting to 21lbs on the bike.
For tires you really need to weigh them before buying eg.
My RR EVO front 2.4 has a claimed weight of 530 grams. I found 2 light ones 490 & 478 grams.
Conti RK SS 2.2 claimed weight of 480 grams. I found 2 445 & 446 grams.I've seen pics of these as light as 431 grams.
If you want to get to 21 lbs. I would go with Extralite Ultra hubs (they are even lighter than the Tune hubs) Sapim Superspokes, Alpine Rims.

well, I can do all that but not all at once... maybe like in a year or so. Not sure how much I want to spend at the moment, but I know more or less how much the components cost...

ManchVegas, I kind of need my 2x10 for the trails I ride. Thanks!
