This is stupid. I need to loose 4 oz or 113.4 grams...just because. Set a goal of a 17.x lb bike and I'm almost there...18lbs 4 oz ready to ride. Let the ideas flow.
2013 Specialized Stumpy SS
Spec Chisel fork
1400 gm carbon wheels
XO crank w/ bling ring
KMC X10SL chain
Surly 20t/22t cog
M785 XT brakes
Conti X-King Protection Tubeless (Have a set of racesport RK's that would get me there in the summer, but it is wet out now)
Spec Foam grips
Spec Bar Ends (this would also get me there, but it is a do not delete)
S-Works seat post
Spec Phenom Cr-Mo (Easily replaceable)
SL-K Flat bar (~640mm width)
Egg beaters SL
(2) Spec Z-Cages
Avid Rotors 160/140 G2
Ti spindle for the Egg beaters SL = - 40gr
What's the Spec Phenom Cr-Mo weigh? San marco aspide carbon fx is 134g and comfy.
G2 rotors are fairly heavy. Perhaps get a set of the new ashima ai2s.

Spec Chisel fork - weighs?
S-Works seat post - weighs?
Spec Phenom Cr-Mo - If you like the shape upgrade to a lighter rail model.
SL-K Flat bar - weighs?
Spec stem - probably heavy or is it a rebranded Syntace?
Egg beaters SL - Get Elevens.
Are your WB cages light? Blackburn Slick are 23 grams and cost 12 dollars. I haven't broken mine or dropped a bottle.
Didn't know the Ashimimas would save that much, especially for the $! I'll do than and swap the saddle for something lighter. Don't spend that much time in it anyway lol. The egg beaters are starting to show their age too, good excuse to upgrade! Thanks all for the ideas.

You can hit it in one shot by changing saddles - an eBay carbon one runs ~110g and assuming your Phenom is in the 230g range, you can hit your goal for $50.
If you buy the Elevens keep your receipt. They have a 3 or 5 year warranty on them. Chances are you'll break them before the warranty runs out so keep that receipt.
Sees to me that there is a lighter cog out there than a Surly. Second the rotors..try the Alligator Serration from Pricepoint. Probably could get carbon cages too.

This is why i love the ww forum, all answers are in the form "-Xg for $Y".
You guys rock.
They're justified and they're ancient and they like to roam the land
Btw, met the goal...got the stumpy ss down to 17.x tonight w the ai2 rotors and a toupe saddle...first ride on the morning. Thisis becoming an addiction! Pretty sure i can get it into the low 17s high 16s without alot more cash outlay.
Thanks all for the help... I'll post a pick of it tomorrow.

Rotors, cages, stem, and saddle should get you the most bang for the buck
Maybe then you will need another 4oz to you can hit 16.xx
