Hey guys, new to the forum and I thought I'd share my "weight weenie-ization" of my Trek 9800 OCLV (1998). Here is the current and proposed setup:

OLD SETUP:

Control:
Easton EA70 bars
Serfas grips (81g for the pair!)
ControlTech 130mm stem
DiaCompe Aheadset
XT pod shifters/brake lever combo
Marzocchi Z2 bomber fork (HEAVY)
Specialized BG saddle
ControlTech 27.2 seatpost

Drivetrain:
Deore LX FD
Deore XT RD
Sachs chain
XTR Ti rear cassette
Deore LX crankset
UN51 BB (JIS)
PD M-535 pedals (422g for the pair)

Wheels/tires:
XTR hubs/WTB rims/unknown spokes
XTR skewers
Specialized Nimbus EX tires
Specialized tubes w/sealant (heavy)

Brakes:
unknown cantilevers (center pull)

NEW SETUP:

Control:
Aerus MX carbon riser bar
Titec pork rinds grips
Ritchey WCS '05 130mm stem
Token needle bearing headset
XT pod shifters/indicators removed
Cane Creek Direct Curve levers (175g/pair)
Marzocchi Z2 bomber fork (HEAVY)
Velo Ti Saddle
Thomson Elite seatpost

Drivetrain:
XT FD
XTR RD, tuned with Ti pivot bolt, slotted jockey wheels (sealed bearing)
Sachs chain
XTR Ti rear cassette
FSA V-drive triple crankset, tuned w/SRP chainring bolts
FSA Platinum Pro BB, tuned with FSA alloy M15 bolt
Crank Bros. Candy C pedals

Wheels/tires:
XTR hubs/WTB rims/unknown spokes
XTR skewers
Specialized Nimbus EX tires
Stan's tubeless system

Brakes:
Avid SD-7, tuned with Ti pivot bolts

Sorry for the extra-long post. All comments/suggestions welcomed. My eventual goal is to get the bike under 20lb. I know I will need to get a new fork, I've been pricing out used Sid forks on Ebay.

This is a great resource, and I'm sure I'll be frequenting the site regularly. I have a gram scale and I'll be doing a massive post comparing actual weights/prices paid for components and net loss in grams.

RIDE ON!

to the board. You will now slowly develop an addiction to it! ha ha

You should post this on the MTB forum, you'll get a whole lot more replies.

a few quick observations...

your Thomson Elite seatpost while very strong is not the lightest...
I'd consider USE Alien Carbon post..

the Sachs chain can be bettered with a KMC-X10 (10 speed chain, but works just fine on 9 speed and off-road).

XTR QR are not light (120g a pair).
Consider Heylight Ti QR at around 55g a pair

Specialized Nimbus EX tires are 600g a piece. I know they have "helpful" "flack jacket" protection.
Why not try Nokian NBX lites? THey are a 480g 2.0 tyre. As opposed to your Nimbus ES 1.5's at 600g.
