I searched for this and couldn't really find much.

Weight: 30.55
Frame: 99 Specialized Hardrock
Fork: 06 Manitou splice comp, NOS
Front wheel: DT swiss onyx/wtb speedisc rim laced with dt swiss spokes
Rear wheel: Stock weinman rim w/ acera x hub
Front brake: Avid juicy 7
Rear brake: Lee chi V brake
Front derailleur: 09 Shimano Deore
Rear derailleur: 09 Shimano Deore XT
Crankset: Specialized strongarm stock
Tires: Specialized hardrock'r
Bar: Stock aluminum thing
Stem: 6 degree rise 110 mm specialized stem
grips: oury
shifts: Sram MRX-201
Seat: Selle Royal something or other sleek looking
seatpost: stock aluminum
Pedals: Shimano SPD, old

I have a 2009 XT FD waiting for my store to get the 2010 race face deus crankset. Soon as our distributer gets it so will we.

^Any idea on what those will bring the weight down to?

So, what can I do for lighter? I want 29 if possible, lighter the better

Lighter- work on those wheels and tires. Fork, too.

The front wheels new, rear wheel, yeah. I do want to get some new tires - suggestions? I do commute on it as well as aggressive XC so i need something for both.

I don't know of any tires made for both commuting AND aggro XC. Look for tires in the sub-600gram range.

Hutchinson pythons are 545, 105 grams lighter than mine now. I don't know if my frame can clear 2.1 though.

wheels, tires, cranks, fork should ekk out some weight. From there I'd go SRAM X9 to ditch the 10yr old stuff.

The best returns will be on wheels and tyres as reducing weight here will yield the best performance increases as if it spins, making those parts lighter is always better.

I just swapped out the disc wheels and brakes on my Rocky Mountain Blizzard for some new hand built wheels and XT V brakes as I ride XC and don't need any more braking power than what the XT dual pivots deliver.

It was already a light bike but I lost a considerable amount of weight by losing the heavier wheels and brakes and the improvement in performance was quite stunning... I am still running the same Specialized Team tyres as I really like these on our trails as they roll out fast and stick like glue.

Alright thanks. It doesn't have 10 year old components, it has 2 week old components.

the fork is probably heavy. get a rigid, or a lighter, short-travel airsprung fork, like a reba or some such. as someone else said, getting lighter wheels and tires saves rotational weight, which makes a way bigger difference. other than that, really, it's gonna be a hardrock regardless. Still, 29lbs is a very attainable goal. Start with the fork and wheelset with some light rubber--- save the old wheelset for some slicks for your commuting, don't kid yourself into thinking that you'll enjoy some sort of compromise tire on the trail. If that doesn't get you to 29lbs, it'll probably still make you happy. If not, you'll need to lighten up the rest of your components

Alright. I want to stick to the front wheel, but I'm looking at a new rear.

Any suggestions for rear wheels and for tires?

Dropping 2-3 pounds off the gut is generally a lot cheaper purchasing new components. But, that's just me.

good luck.

I agree. Work on your mid-section, backside and strengthen up the pistons. You'll be good to go.

Its not that I have a problem climbing or anything, I just want to be able to say I have a sub 30 pound bike.

Then just lie...it's the cheapest solution.

Lose the shifters, derailleurs, cables, big/granny rings, and I would say cassette (but you don't have one listed, so maybe you already ditched it). Pick a good 2:1'ish gear ratio and enjoy your new 26lb ride.

I live in a very hilly area. I would die.
