Hi ya guys :D

I'm in the process of loosing some weight from my bike and was wondering if the good folks on here could give me some solid pointers on shedding some vital poundage on what one of my friends describes as my sack of spuds bike :lol:

Here's the spec so far...

Rock shox U Turn revolutions.... want to keep
DT Swiss EX200 rear shock.
Race Face Ride Stem and handlebars.
Deore shifters.
Deore crankset (9 speed).
Pace BB
A mix of Simano front brake and Avid Juicy rear brake (being replaced by XT front and rear).
XT front and rear Wheel-set - with XT skewers.
XTR M972 rear mech.... want to keep
XTR M971 front mech... want to keep
Thomson seat-post... want to keep
Vigo seat... want to keep

Any help would be greatly received this end :wink:

Nice bike.

Rock shox U Turn revolutions.... want to keep:
Race Face Ride Stem and handlebars.
Deore shifters.
Deore crankset (9 speed).

Air forks would make prob the biggest weight loss,
Lighter stem and carbon bars.
Not much difference but XT/XTR shifters
XT/XTR crank would be a lot lighter than the Deore one.

Everything else I wouldn't change. :wink:

Do you know the weight of it as it is??

Tubless tyres I was told will shed a kilo :shock:

Tubeless tyres aren't as light by some way as non tubeless versions so really doubt you'll save a kilo there. But tubeless do roll better, offer better puncture resistance and run at lower psi so give more grip. I've been looking long and hard at tubeless tyre options and its tempting to try to save weight with trying to make non tubeless tyres work with sealant but this involves a fair bit of faffing about so I'd go for some proper UST ones from the likes of Hutchinson or Schwalbe. Lots of choice here but its always going to be a size/grip trade off against weight. I'm quite fond of Hutchinson Pythons which aren't bad all rounders (not for Winter mud though) and weigh in at about 650g which is pretty light for UST.
Tubeless ready is another option and potentially lighter but for simplicity and durability UST is the way to go IMHO.

Definitely 2nd changing cranks for some XT HT2 ones and some carbon bars also is a quick an cost effective way to lose some weight.

Here's what I'd do:

Replace the stem for a nice Thomson to match the seatpost.
Replace the bars with some nice Easton Carbons.
Stick with inner tubes and go for a set of lighter tyres.
CHANGE THE CRANKS! (I've got some nice BRITISH Middleburns for sale ;) )

To be honest, the setup you've got is all good quality stuff, and I would have thought you'd struggle to drop the weight significantly, unless you were prepared to spend quite a bit of money.

How much does it weigh, out of interest?

Sorry guys, I've not been able to weigh it as yet; I might get a chance this weekend...possibly :o

I'm running tubeless at the moment :D

I was thinking of getting an XTR crankset and change the rings for Extralite ones. Also going to get hold of an XTR cassette and Sram 991 chain.

What bars and stem would be a good choice do you guys think? I'd be tempted to get a Thomson but they're not that light from what I remember seeing - could well be wrong on that count :D

Hey ya Barny :D

I've always been a fan of the Middleburn stuff. How much weight is in yours compared to an XTR M970?

What length stem and width bars are you after ? I may have something to tempt you.
And please buy Barney's KCNC skewers (before I do) as Shimano skewers are not light. :wink:

How much you looking to spend? As loosing weight is a wallet busting hobbie.

CHange the seat to a 100% carbon seat. Stem & bar go Carbon as well?

LOL @ the skewers comment.

I'll have a look at what my stem is and give you a shout :D

I'm going to keep that seat (unless something just as comfortable is on the market and lighter) as the last seat I had on my old bike wouldn't have looked out of place in a 15th century torture chamber. That one was a carbon jobby that had me in agony whenever I rode. Never again will I subject my knackers to such torment.

I don't mind going carbon in the slightest, that is as long as an alloy alternative isn't lighter :D

You mention your mates thinking your ride is lardy.

Are they on full sussers too?

It doesn't see so lardy to me, considering the travel it has I would want to have fairly beefy gear on it.

You will pay a lot to gain little, unless you radically alter the suitability of the bike for the task it was made for.

I would think about speccing up a nice light hardtail, or getting a superlight XC machine.

Otherwise carbon bars and a lighter wheelset, and the lightest tyres you can cover your terrain in.

Couple of hundred spent on lightweight clothing is an idea too.

Hey ya highlandsflyer

You talk a lot of sense. The fella I mentioned has a hard tail so there really isn't going to be a sensible comparison made between the two bikes.

A change to a lightweight crank, cassette, chain would make a fair bit of difference I would have thought and not compromising the bike like you're suggesting would be made if weight saving went to the extremes :D

Doubt it is even heavy in the first place ?.

The only thing I would do to save a chunk of weight would be to "1 x 10" it. 34t Hope ring up front (from wiggle), with a superstars chain guard and 11-36 cassette on the rear. Thus removing the 2 outer crank rings, the front shifter, front mech and all associated cables, what you get for these on ebay will near enough cover the cost of conversion.

Here is mine

ps: It will also significantly increase the look of the bike, triple cranks are minging, and yours is a shocker :lol:

This is an 130mm travel frame. Not sure why your forks are wound down so low. Can they be wound back up to 130?

If they can't then change them for some 130mm air forks.

Don't think there's anything really lardy on there. Only way to save serious weight is the fork and running non-UST urban tubeless tyres (which I wouldn't do personally).

If you think it handles badly, it MIGHT be the forks that are the problem.

I'd rather stay with the biggest chainring that I can get on the bike, that being a 44t at the moment :D

You're right about what I've got on there (crankset-wise) at the moment. Not too sure to go with some Exralite chainrings or just go all guns blazing and pick up a secondhand XTR 9 speed.

The reason my forks are low is because I'd just been riding on the roads. Same goes for the rear shock - both can be locked out :wink:

I didn't say that it handles badly, bit lost as to where that came from? It handles very, very well. I'm a fan of the forks I've got on there already.

As I've already mentioned, I'm running tubeless.

I'm waiting on an XT rear cassette, could have gone for an XTR but there's not too much in the XT and XTR cassettes. I'm also waiting on a Sram 991 hollow pin chain which would lighten the load a touch...
