I'd be willing to bet a few bucks that it's one of the lightest VT's on the trails.

You could....

Go 2x9 and loose a chainring
Cut off the excess seatpost sticking out of the seat tube
Loose the bottle cage
Get a lighter seat
Eat only 1000 calories for 10 days

Well lets see. First I'd swap out the frame for a nice hardtail. Then I'd ditch all that shifting stuff....

Babar · Aug 20, 2003

Is there a limit or exception because i think i can get that thing pretty light.

Babar · Aug 20, 2003

Post teh full spec.

Westy · Aug 20, 2003

Try some lighter tires. Mosquito or Python airlites are feathery, work great and are pretty damn wide for 2.0" tires.

28.5 is right in my ball park. I built a small XTC hardtail with disks at 27 LBS!!! And I can climb on it all day.

My **** *22 weighs in at 28.5 now that it has disks - climbing on that is no problem either.

My suggestion is too eat smaller meals.

Well what does that fork weigh? My SID weighs 2.8, I think the race version is 2.64. If I swapped the SID from my **** *22 with the marzochhi on my hardtail - it would loose 2 lbs.

But then my blues would clash so I ain't gonna do it.

You could get some of those titanium Egg Beaters. Those would certainly shave some weight off that bike. But they do cost like $400.00...

That thing is big bucks! I hear its nice though.

Zark · Aug 20, 2003

The bike is light enough James, its time to ride it dude! My HT is 3 pounds heavier! We know where the weight needs to come off dude

btw What are you up to on Sat? We're talking about a house warming party, Interested?

Babar · Aug 20, 2003

Your Titec AL-235 seat post is, assuming its 350mm - 304.5 g
You can swap to Thompson, Tune or USE and shave 100g off easy or more.

About tires, are you using UST ? (tire is where you would shave most weight) or Tubes or Latex ?
If you convert to Latex you can shave alot of weight since your not using Boat Anchor UST tires. Lets say your changing to Latex
250g average (both wheels) for Stans and Eclipse and good decent 2.0-2.35 tires weigh 400~600g and you can also shave huge watt from rolling resistance.

Shave off another 150g by changing all your bolts to AL or Ti combo.

Egg Beater 289g how bout Corratec Easy Click Ti 243g

XT Disk Brakes weight Average of 900g.
Magura Marta weighs 700g average or Hayes Mag-plus under 800g, Hope Mini's also under 800g .

I think Easton EA70 Stem is around 200g or more save 50-100g by going to FSA XC-120 151g or Syntace f99 99g which is strong and stiff than most stem out there.

Sram 9.0 Casette weighs 294g, Stronglight is 204g, XTR is 240g XT is 260g, Inferno 149g. Shave 40-140g here.

The Easton XC riser carbon bars weigh average of 150g-160g depending on length 620mm is longest i believe.

Hope this helps. Oh and rolling resistance would make the most difference.

Frame: 20.5" VT
Lighter shock?

Fork: Psylo Race Air
Maverick?

Wheels: X-Max Disc
King ISO hubs - laced w/ ti M2 spokes to Mavic X317's...why not?

Tires: Mich. 2.2 Hot S
Tioga Red Phoenix 1.9

Stem: 120mm Easton EA-70
Thoson Elite, about 18-20 grams lighter

Bar: Easton Carbon DH (thinking of going to the regular 175gm carbon XC bar...)
XC bars are lame - stick with this

Post: Titec AL-235 (thinking of going to Easton carbon...)
Go for the carbon

Seat: WTB Laser-DH (will swap to a Laser XC, a little lighter)
Stick with comfy, if the ass requires it

Cranks: '03 XT
XTR

BB: '03 XT
XTR

Shifters: SRAM X.O
No problems here, move along

Front Der: '03 XTR
No problems here, move along

Rear Der: SRAM X.O short cage
No problems here, move along

Cassette: SRAM 9.0 11-32
No problems here, move along

Brakes: Shimano XT (I could go to some non-braided steel housing, plus it woudn't scratch the frame up too...or alloy rotors.)
Hope Mini?

Pedals: EggBeater w/SS spindle
Egg beater Triple Ti - well you asked for it!

spincrazy · Aug 20, 2003

The post and handlebar swap will lighten for sure. Going tubeless will as well, and you'll notice it more. I can't believe the Race weighs as much as it does, my Pyslo SL weighs that or less - could be due to the shorter steerer. Go to a lighter cassette and you're set.

I think it's plenty light right now though.

bomberz1qr20 · Aug 20, 2003

BTW - my SS hardtail comes in at a full 7 lbs heavier than your FS bike.

Let's hear it for cro-mo parts!

:rolleyes:

Babar · Aug 20, 2003

Remember Pyslo race is lighter than Matitou Black or Fox Vanilla and Marz etc... Pyslo SL also weighs more than the Race.

Zark · Aug 20, 2003

I'd skip the Maverick James, DC's suck to climb with. One hard knee to crown impact is all the convincing I needed. :dead:

Stem, post, tubeless. This alone could be good enough for almost a pound.

Babar · Aug 20, 2003

I think the cheapest and easiest way to lose weight is, change the Seat Post, Seat, Stem, Handlebar, Casette and Tires. Biggest change you will actully feel when riding is from Tire and Tube. Eclipse or Stan will save 5w from each wheel so 10w total. And Tioga Red Phoenix has one of the worst rolling resistance and ride quality. I think Schwalbe, Continental and Nokian (NBX series) are best in terms of rolling resistance and grip.

That's the spec...

Ok, I admit I didn't read everyone elses ideas so if I repeat, forgive me. I'm not a weight weenie myself but some I ride XC with are true WW.

Fork: Could go SID but I never would, keep the Psylo
Wheels: Ditch the XMax and go for American Classic hubs laced to Valiants or 317s. (SPAM - our new rims are going to be extemely light, check them out at IB)
Tires: Kenda Karma Stick Es, 480g is the heaviest and we've had them at 437g for a true 2.0
Stem: Ritchey WCS or my personal favorite a Thomson
Bar: Easton Monkeylite SL if you like a little rise
Post: Easton EC70
Seat: Could go lighter than Laser but that's what I ride and like
Cranks/BB: either keep as is or switch to FRM ISIS BB and cranks
Brakes: Formula B4SL with Stan's rotors, Martas would be a close second

Other things would be swapping bolts, lose the bottle cage, go tubeless just because, etc.

Good luck.

llkoolkeg · Aug 21, 2003

My Els Isis is 31# and I thought I had built it up pretty light.

Have you tried concurrently getting a haircut, trimming your nails, inhaling helium and taking up bulemia?

does everyone at your office keep their bikes in their cubes?

are you hiring accountants?
