[Closed] Where to save weight from this build?

Take the pie shop number off speed dial 🙂

Swap the Louise brakes for Marta's with skinny rotors.

Some of those hoses and cables could be shorter too 😉

Thomson stem & Hope seatpost are nowhere near the lightest,

It's a 20" frame - so make sure you're comparing it with others that size.

Seems like a lot of folk quote weights without pedals.

FWIW, I wouldn't guarantee that the scales you used are particularly accurate, so it could easily be a pound or so either way.

you could remove the bottle cage too.

Pie shop removed from speed dial 😆

I do love a long cable 😳 Only just fitted them too 🙄 😆

Any recommendations on a different stem & seatpost? Am I likely to save much?

I do have some Ashima rotors 160/140 but have yet to fit them

Where would I put my racing beer?

Trying to go without the Camelbac hence the cage

The last time I played this game, I reckoned that I was was spending £1 for every gramme saved and that seemed fairly consistent across components. I reckon that it'll be more than £1/g now.

You don't need 3 chainrings for racing.

Ti seat post? Lighter tubeless wheels?

Stem. bars, seatpost and pedals are all heavy (relatively). Most bike weights are quoted w/o pedals, and those XTs are at least a quarter of a pound over some of the alternatives. Replacing the other bits with KCNC parts would save quite a bit at a reasonable cost and the Ashima rotors will save a few ounces.
Fwiw, my Anthem weighs 24lbs dead without pedals but with crud guards and a heavy SDG Bel Air saddle. Next items for the weight loss programme are KCNC rotors and skewers, and a lighter saddle.

grips for the greatest g/£

esi grips are lovely.

Silly question but is there much weight to be saved going tubeless.

The wheels are tubeless ready with Stans tape - I would just need valves and some goo.

Am looking at a Ti post but not sure this frame has an alloy ST insert - trying to avoid issues caused by Ti on Ti

I think I do 😳

Could maybe shed the outer ....

As you say - seatpost, stem and handlebars - change to Thomson Masterpiece, Easton EC90 stem and handlebars, in addition, saddle and tyres, also go tubeless and use sealant and something like rocket rons....done...

FWIW, you could take a pound off changing the wheels & tyres to something like American Classic Tubeless & Rocket Ron Pacestar TL's but that's throwing £400 at it.

Are the tyres heavy at 465g?

Saddle - despite its bulky looks is pretty light - but I do have a Flite Ti that is lighter.

Makes me feel a bit better seeing his before build at 10kg.

I only have to loose 1.2 kg ......

Carbon seat post & lighter saddle. Not cheap for the amount you'll save but if you're out to save regardless of the cost then it's not a problem

Well, my Ti has a Ti seat post made by the same manufacturer! It looks lovely too.

DT Swiss forks - seriously light.

mmm...they are quite light, certainly only save a few grams with a tyre change so probably more worth going tubeless and taking 200g out of each wheel...

swisstim, the EC90 stem costs £180 and weighs 110g - the KCNC SC Wing costs £57 and weighs 100g. The EC90 bars on the other hand are ridiculously light - I remember when 135g was considered suicidally light for narrow, flat bars.

rigid forks
singlespeed
v-brakes

Go to http://www.xcracer.com/shop/ and get your credti card out.

The mt zoom and scandium stuff is stupid light.

I only discovered this shop after I built my XC bike and now think it's a bit tubby.

24.5 lbs seems heavy...

What is the frame weight?

I had a 21.5" Airborne Ti HT that weighed in at 23ish lbs - note overly gucci kit, and Pace HT at 24.5, but with fairly robust kit on it...

I've found the SDG integrated saddle / post is a useful way to save weight.

Frame is 1800g or there abouts.

Seems that 6oz is easily achievable for not a huge sum of money:

Current bar 265g
EA70 Flat bar 165g

That's 3 1/2oz for £35

Grips must weigh near 100g for the pair.

FRM from On One are about 25g for the pair

That's 2 1/2oz for £6

Struggling to find the listed weight for the Hope post.

You don't need 3 chainrings for racing.

I think I do

Saving another lb or two off the bike might not make much difference to pace then?

Tubes, seatpost, stem, after that it's silly money. And the stem will be barely worth changing.

As you say, you'd need to replace everything with expensive only slightly lighter kit to get properly light, but that's how it is with light bikes. The savings are small ones, but on every component.

Weight isnt the "be all and end all" with a Ti frame anyway. I believe that alu and carbon are much lighter frame materials.

Go 1x10

Wheels - American Classic or DT 240s built up with Stans Podiums, DT Supercomps or Revs and ally nips, then run tubeless.

EC90 bars. KCNC stem. Thomson Masterpiece seatpost, Selle SLR 135g saddle.

Plenty of brakes lighter than those - XTR?

Ditch the seat QR for a bolt up one.

Wheels aren't particularly light, could got DT240s on Stans Alpine or Crest if you're heavier.

Good point Onewheelgood - it's certainly a cheaper option, just go careful with those tiny bolts. Mmm...I still have a Pace 130 flat bar at home...it was the bees knees for a short time.

Hope seatpost according to the Hope site is 235g - surely not a huge amount to save here either?

Thomson Masterpiece dependant on length 250-330mm is going to be 140-180grams...Looking at the pic you are going for a 330mm so another 55grams shaved off, but 60 quid spent...

Put very light thin tubes in.

These will let you stop for regular puncture breaks inbetween going fast.

there are much much lighter, comfortable saddles available try the selle italia gel SLR XC think its 170g but there are also much much lighter saddles;

what about seat post, do you need all of it? i.e. the bit in the frame, work out what the minimum insertion is, or it may be marked on it, then chop off the bottom.

Spacers on your stem, change to carbon?

handlebars & stem clamp - carbon

rear mech - is it a long cage? you could pprobably get away with a medium cage, as long as you think about what your doing when shifting (no big-big)

tyres go for something lighter - nobby nic evos? 2.1
tubes go for somethign lighter - try Continental MTB 26 Light

Skewers - titanium? - X-Lite Tech 9 Titanium?

DT Swiss forks - seriously light.

Magura Durin SL 1200g about £700 😯
DT Swiss XRC 100 Twin Shot: 1170g About £1035 😯 😯 😯

All depends how deep your pockets are

If you want to race, 1x10 with a decent light cassette will save a load of weight. You're getting shut of a front mech, shifter, cables and two rings plus bolts. Might need a front chain device but the MRP one is cheap, or I've had good results with the XTR rear mech with the clutch thingy.

Wheels will make a massive difference, probably the first thing I'd change.

Those bars are also heavy, and get an FRM ti clamp to replace the QR one you're using.

Are you anticipating being near the pointy end of the race? If not, will your enjoyment of the "event" be significantly improved if you spunk £1K at this bike and loose 1kg from the weight and go from being 100th fastest looser to 96th fastest looser as a concequence?

Just sayin!

Agree with the above, spend the cash on some really nice kit like Sidi shoes, and quality bibs and top.

I appreciate the honest approach 😆

I'll enjoy the racing either way - more so as I will be placing right towards the back anyway.

It would seem that being sensible and not spending a huge amount (sub £200 easily) that half a pound could be shed.

Would be nice to be in the 23s rather than nearly 25!

OK then, grips, bars, stem, post, and saddle are the classic places to start. This years XCR Pro, (by Shimano), range is excellent and well priced, else take a look at the shop at xcracer.com for ideas.

Careful though as its a dangerous path to take, next it'll be 1 * 10 with a new XTR/XX cassette.

It's a 20" frame - so make sure you're comparing it with others that size.

Red herring that. Bigger difference between identical tyres than frame sizes!

Carbon stems are daft, light alu all the way. Mt Zoom stuff is excellent, and very good value.

Would be nice to be in the 23s rather than nearly 25!

Park scales are lbs/oz, so it's 24lbs 8oz, not 24.8lbs, ie it's actually 24.5lbs.

Quick wins (significantly better than £1/g) :
- tubeless
- foam grips (there's >100g for £5)
- Mt Zoom bars
- Mt Zoom one piece bolt/top cap
- Mt Zoom seat clamp
- Fit those rotors you've got, if they're not the lightest ones, get KCNCs

Beyond that I'd do stem (KCNC)/seatpost (Woodman do some nice ultralight ones, or I've still got some New Ultimate ones which are v nice, but not particularly cheap),

Quick wins (significantly better than £1/g) :
- tubeless

Thanks guys.

That's it 23 1/2 lbs (maybe even less) here I come!

I have had a look at the XC Racer site - lots of lovely light bits on there 😯

Not always; generally yes, but if you have a heavy TLR tyre and lots of tubeless gunk, light tubes and tyres will pip it.

He has 465g TLR tyres, so I'm assuming a couple of turns of Stan's tape (in place of existing rim tape), valves, splash of sealant. Minus the weight of tubes.

Ultralight tubes will be cheaper, and probably similar weight saving, but won't work as well. Depends on what you wanna achieve I guess, and that's a whole different argument.
