Lighten my full sus

The overall weight is the sum of ALL parts
Ideally you need to create an Excel spreadsheet, listing each component and it's weight. You can then go internet shopping for lighter parts and get a good idea on the £ per gram weight saving. High £/g is bad, low £/g is is good
The obvious answers will be:
Wheels
Tyres
Tubes
Saddle
Bars
Stem
Seatpost
Once past that stage you will find it increasingly expensive to save grams here and there

Wheels - Mavic 819's, Hope Pro2 and Pro3 hubs on DT Swiss spokes. Not the worlds lightest but sturdy, reasonable weight, not all at the rims and UST.Ideally you need to create an Excel spreadsheet, listing each component and it's weight.

Tyres - For the events I will be running 450g race tyres.
Tubes - None, UST
Saddle - fizik gobi, considering upgrading to the new light fizik gobi.
Bars - Easton monkeylight Carbon Fiber
Stem + Seatpost - Thompson finishing kit
I have covered off the usual items and now I am a little lost as to where to go.
It's possible to get disc wheels down below 1000g per pair now. Thomson Elite seatpost is heavy, Thomson Masterpiece is much lighter. Tune Speedneedle saddle is 87g for example. Maxxi's MaxxLite tyres are 310g each, saving you 280g per pair for example. This is why I suggested doing a spreadsheet and listing all component weights individually, it will soon be obvious where you can save weight.

27 lbs is pretty light for that sort of bike, if you really want to go much lighter you're going to have to look at carbon frames. You've got a solid bike there, it would be a shame to compromise it with some flexy parts for the sake of lightness. a lighter seatpost or uncomfortable saddle isn't going to make a drastic difference.
What forks are you running? Rockshox Sids are available in 120mm QR15 format now, would go very well with your bike and if you're flush the worldcup versions will save a lot of weight.
I'd be looking at different frame sets though personally, the carbon Treks get great reviews and the new Scott Spark (4.3 lbs!) is very nice and extremely light for a trail bike. Specialized always leave me a bit cold but some of their bikes are good.
a quick google suggests your frame weighs about 7 lbs, so there's a lot to loose there.

Is there any chance of losing weight from yourself, or are you already skinny?
Already doing that, 8 lbs of lard down already!shalmaneser said:

I totally agree! I know a guy who has built a 23 lb '5. He says it was so awful to ride the config was changed very quickly. At the mo, Mrs Gooby is expecting so a whippet trek is not on the cards, I have ridden a few and didnt love them anyway, the Santa cruz was more my kinda bike... What forks are you running?

I would like to shave some grams off here and there and get her to 26 lbs for the 100 miler. I didn't realise the Thompson stuff was weighty, any suggestions on so light CF alternatives? How about the front mech, currently XT, is the XTR any lighter?
The only place I can really see a loss or weight are the wheels. 819's are not a light weight rim (not when you take the threaded nipple inserts into consideration, Mavic list the rim weight without them) If you are a smooth rider you may get away with some ZTR Arch EX rims. 819s are 500g with inserts, Arch EXs are 400 and all you need is one layer of the yellow tape to make them tubeless (must weigh 10g or so) 90g weight saving at each wheel is not massive but could be worth it.
If you are considering racing enduros I would be going heavier in most places not lighter! 450g tyres aren't really up to the task IMO and you want to be fitting a dropper post too.

Interesting - not sure why I would go heavier? - the build is "burly" at this time. The main reasin for this is I am dont have the most finesse in the world. Though my problem is now mostly wearing things out rather than breaking stuff, I still prefer to be on the rugged side of the equation. I am still learning to ride. That said, I am sure there is weight to be saved.If you are considering racing enduros I would be going heavier in most places not lighter! 450g tyres aren't really up to the task IMO and you want to be fitting a dropper post too.
Last year I did the ride on 650 g tyres, fresh for the ride and had zero problems.
I tried a dropper post and I really did not like it. when in the higher riding position it had play and movement and dampened the feel of the bike. Cant say I will be getting one.
I like the idea of getting some nice light rims and using existing hubs... any ideas? has to be UST.
I currently use a SRAM chain with hollow pins. Is there any other options?

Sounds like congratulations are in order mate! 8lbs is great!
Give our live to Mrs G, the 2nd one is just as much fun.
Hi Mate! I forgot to tell you, you are doing the 100 miler with us.Give our live to Mrs G, the 2nd one is just as much fun.
8lbs is a good start but minimal when you realise how much "desk spread" has to go!
I have lost lbs, Mrs Gooby has found them is is fast aproaching "big pregnant whale"!
(So hope she doesnt read this)
Amongst other rides, I am riding the South Downs 100miler. It is a huge distance with a huge amount of climb. I am loosing the lard, working hard to get fitter but I dont see why the bike shouldnt do its bit.
The basic question with everything is do you want to carry it 100 miles with over 10,000ft of climb in one day! There is a load of desk spread that has to go. I am pretty sure there is lard on the bike that has to go also!
I have just replaced the jockey wheels (they looked like throwing stars) with some KCNC ceramic bearingd blue aluminium jobbies. I am not sure if they are much lighter but they are a breath of fresh air. They have eliminated jockey wheel play and the gears swap so much better. The drive is far quieter and sweeter.
I have also got some titanium bolts for the brake discs. They were cheap so I am going to give them a try!
