[Closed] Show me your lightweight XC speed machine

Now this is a light Scapel, (not mine, but a friends), sub 8kg!

Quite a few changes between the two bikes.
Mostly detail. Also mine is a 1x10 using sram xx with a fair chunk saved with the new crank.
Formula r1 brakes with kcnc rotors and all bolts in Ti .
Ec90 bars - kcnc post SLR saddle and tyres are around 440 grams each - sram red cassette

As with all light builds its in the details so please don't be so quick to dismiss.
Mine started life as a 2011 scalpel 1 so can you not see where weight can be saved on the stock bike?

Happy for you to come over and weight it

Double post

Argh triple post 🙂

.

wow a triple post!

Red cassette, interesting, what range is that for a 1*10 setup?

I know - record for me 🙂
It's a 36 / 11-28. I ride a single speed with 32-14 gearing so thought I'd give this gearin a try.
Previously went with 34 /11-27 on a Merida 96 which was too easy to spin out on the flat but fine on the climbs.

But it's got comparatively heavy wheels. I'd believe 19lbs, but not 18. A friends Flash Ultimate with some lighter bits was 18lbs.

Bloody nice either way, except for the lack of gears. Proper cassette and it'd be great!

I tweaked my main ride this weekend. [url= http://singletrackmag.com/forum/topic/is-actually-possible-to-get-a-tyre-on-ztr-crest-rim/page/3#post-4209761 ]I built these wheels last [s]Summer Autumn[/s] Winter [/url] and hadnt got round to riding them yet. I wanted to have a go at putting together a really light tubeless set (1,770g). Ive hardly ridden this winter as the conditions round here have been unremittingly nasty, but now that Summer is here Im thought Id get the bike sorted. And for showing off at bespoked this weekend 🙂

This now comes in at 9.6Kg (a little over 21lbs). I could probably shave 100g from the BB and another 150g from the pedals if I really wanted to, but that would probably cost about £1 per gramme which I think would be going too far...so I dont think I can reasonably get this under the magic 20lb mark

(Oh and that chain weighs a bit, so perhaps another 100g off that)

What went wrong? 😉

😛 had to use sapim leader spokes as that was all that was in my spares bin.

Bang on 20.....

How is there only 2.5lbs difference between a hardtail carbon Scott 29er with tubs, carbon rims, and XX, verses a FS Giant 26er with 3*9XT?

Stunning bike there Riverdog!

Stunning bike there Riverdog!

+1, that's lovely! Although you're penalised for taking photos of the non driveside of the bike!

What's the saddle? Is it a Becker?

No way is that 2lbs heavier than the Scalpel!

Some ludicrous weight claims on here 🙂

I'm sure we've discussed that Anthem before!

Got a 20lb Soda. It's a bit to light. Fast thought. If I was not totally incompetent I'd post a picture.

[IMG] [/IMG]

23lbs with pedals

Mrs Blobby's Anthem is over 2lbs heavier than that and it's the teeny tiny ladies size, very similar to that build and with lighter tyres.

[img] [/img]

Dunno what it weighs. Not a lot, probably less if it didn't have a flower pot built into the front rim.

Riverdog, that is very nice indeed. Why Rebas and not SIDs?

Those Nics are only 2.1s and actually I can't remember if it had Nics or Ralphs on when I weighed it. Come and weigh it if you like 🙂

Also, since it's last appearance it has lost a fair amount of weight.
SLR saddle (160g) replacing Bel Air (268g) -108g
KCNC rotors replacing Shimano -120g
KCNC ti skewers (47g the pair) replacing DT Swiss -90g

that's 3/4 of a pound just on those bits. It's also gone tubeless and now has a KCNC BB and seat QR.

That weight was before it went tubeless???? 😯

I'm assuming he's saying the 22.5lbs is as specced now, not as photographed? Ie it was 23.3lbs (ish) when photographed? I'm still struggling a bit, but I'm sure he's not making it up, so those desirable scales are out there somewhere!

Blimey, I wonder how light it would be without all those stem spacers? 🙂

Haha, if that Anthem is 22.5 lbs then my SC Blur xc Carbon with full XTR / XO, Easton EC90, Syntace F109, tubeless RaRa Evo 2.1's on Roval Control SL's must be about 18 lbs on his scales... I'll take that! 😉

The anthem really is that weight - I ride with him have seen/compared it myself.

Very impressive for a FS bike.

The 2009 Anthem X1 was 25lbs out of the box. Losing 2.5 lbs isn't a big ask.

The 2009 Anthem X1 was 25lbs out of the box.

Manufacturers claimed weight...? 🙂

Thanks for the comments on my Scott.

Saddle is a Tune.

Why Rebas? They came new on the bike before it was upgraded, the budget wouldn't stretch to Tubs and new Sids. The wheels at 1200grms gave me more real benefits in terms of speed & stiffness than 200g saved on a fork upgrade.

Interesting. Was holding out for SIDs for a lightweight 29er build but I can find much better deals on the rebas, for the weight saving I may just go reba and spend the extra on wheels.

How have you found the tubs for XC racing?

I need the DTSwiss Tubs in my life...Want

And I thought my scales were optimistic. As long as I have a hole in my arse that anthem doesn't weigh 22.5 lbs. Not a prayer. It's running XT cranks for a start...

A 2011 Anthem X4 out the box is 'apparently' 28lbs. And I think that's probably on the generous side...

Love all the "I saved X grams here" then quoting the final loss in pounds 🙂

RE: that anthem - Because I'm bored I looked at manufacturers given weights and for just the frame, fork, cranks, wheels, tyres and cassette it puts you at 22.5.

It might not be 22.5 but it could easily be sub 23. I have an anthem with a similar spec which weighs in at sub 23lbs on a mate's digital scales.

The Tubs are great for a race bike. I'm sure youre aware of the limitations when you don't have a Scott Swisspower support crew at your race, but the wheels are the revelation for me, they are silly light but the real advantage is they are so stiff. I have always found light 29er wheels floppy, but I think the deep carbon rims are what make the difference.
The tyres roll super fast but it takes some nerve to run them at 20psi. Goes like a cross bike on the fire roads and a soft-tail on the rough stuff. I did try TUFO tyres first, they roll just as fast, but the Dugasts have much more gripand are a bit bigger volume which I like better.

They fastbirds or rhinos?

Interesting comments re Tufo's as that seems to hold true when talking about their cross tubs as well. I think the extra grip comes from the more flexible sidewalls.

Mine are Fastbirds.

Sure this isn't you riverdog?

Pure class at this weekends XC season opener.

The picture is full of epic!!

Even cooler when you're winning a World Cup. Top bloke!

18.4 lb a little disappointing.

disappointing

That ain't bad for non carbon rims and a full range of gears!

Niner AIR 9.

Dont know the weight but it's light enough.

Oh I wish!!!
The look on those kids faces says it all!

Under 22Lbs and raced this for the last 2 and a half seasons but building a 29er now so frame, fork and wheels will soon be available to buy.......

That ain't bad for non carbon rims and a full range of gears!

Agreed! Maxxlite 310s though? Loses points for non useable tyres 🙂

I really don't know why I'm arguing with flange about this, but anyway...

I think he has a problem with his adding up. Here are some manufacturers quoted weights

Frame 2300
Wheels 1463
Forks 1498
Crankset 820
Cassette 280
Tyres 952
Stem 92
Bars 130
Bar ends 46
Seatpost 165
Skewers 44
Saddle 160
Rotors 146
QR 23
Grips 80
Brakes 650
Shifters inc inners 283

which add up to 9132g or 20.1lbs.
What's left - outers, headset, valves, Stan's fluid?

It's late so I could be wrong, but aren't you missing:

Front and rear Mechs
Chain
Pedals
Spacers
Rotor bolts?

I'm racing an onone whippet.
Not weighed it but fairly light
Built up with Rebas and American Classic wheels.
Most of other kit fairly middle of the road stuff
Frame is 1300g

remoterob, it was late but you weren't wrong.

Rear mech 181
Front mech 155
chain 290
rotor bolts 24g
spacers 10g

660g - total 9792, 21.5lbs

Here's my 20" Whippet. 10KG/22LB as pictured in current 2x9 setup.

Jonnyt - is that an LX chainset? What rings have you got on that? Or is just standard but with the outer removed?

I'm loking to convert an XT triple to something like 28 - 38

It's an old XT triple, M760/M761 I think. Removed the outer and changed the middle from 32 to 36, so it's now 22/36. Set limit screws on FD so I can't accidentally shift the chain off. Seems to work okay for me.

Was running with single 32 but my legs couldn't cope with 32-32 on the really steep stuff.

So, what would the 29er to 26er ratio be in this thread? 🙂

Still haven't got round to a proper photo of my new race bike. But here it is in action. Intense Hard Eddie, Full XTR, EC90 wheels and finishing kit. Tundra OO saddle. Time ATAC 12 TI pedals. Hope Race brakes, In full race mode its 20.13. Waiting on Scwalbe Rocket Rons to come into stock, That should just nudge it into the 19 zone. Photos to prove it if needs be.

Interesting reading. Seems a bit dubious given I have the same tyres and they weigh more on my scales, and my wheels (if they are hope hoops) were also considerably heavier.

Having said I'd be interested to know the spec list for this. My medium Anthem is about 26 lbs and I'm keen to shave off a a lb or 2. 23lbs isn't to hard to believe for a lightish anthem.

Here is last years race bike. Pictures with Stans wheels, in this set up it was 23.5. Later on in the year it had carbon EC90 wheels. This brought it to almost 23 pounds dead but never any less. It gets hard at that point to really start saving much more weights. Unless you where to start going down the routes of some lighter and less durable and practical parts.

I've just taken delivery of a 2012 anthem x3. Straight out the box with no pedals it weighed 26lbs 10oz. I added my m520 pedals and it went up to 27lbs 12oz. I transferred my hope/crest wheels and xt brakes. Also got rid of all the SRAM stuff and put my shimano shifters and derailleur on. Weight is now 25lbs 9oz

@tpbiker, they are Hopes but Pro3s with 24 spokes. To be honest, they are a bit flexy and they are the only bits that I've wondered whether my weight obsession is excessive, particularly since the forks are Sids and have a bit of flex in themselves. The tyres are the lightest NNs, the 2.1 EVO Tubeless Ready. All the other bits are KCNC from Clee Cycles - the weights they give on their site are genuine.
Apart from the wheels, the big weight savings were the saddle (XLR Flow), the KCNC Rotors, Bars, Seatpost and skewers which were all significantly lighter than the stock bits.

How's it lighter than Richard's one?!

No way is that 23lbs plumz! Judging by the Anthem that is 22.5 yours should be sub 20!

All those extra spokes? A stem twice the length? Seatpost likewise? Different model year frame? Different forks? Variation in the local gravitational field? And perhaps it's not, perhaps it's just different scales. Why does it upset you so much?

[img] [/img]

Now with Carbon wheels and a slightly better saddle for not chopping one's bits off when getting one's rear off the back...

Oh and a dropper post as required. Great bike.

TOM B - No way, i work very closely in the cycle industry and have a keen interest in light weight bikes, Sub 20 full suspension is impressive, even more impressive if it was alli frame. The past picture i posted shows my new carbon hard tail. That frame ways 1150 grams and even with full XTR and EC90 kit it takes carbon wheel to get it close to 20 pounds.

However it dosent real matter as 23- 26 pounds anthem ride fantastically, Great bikes at great prices that can do near on anything, I have had several Anthems now and they have done Elite national races, South Africa trail holidays, Alpine weeks and 12 hour solos. Couldn't off asked for more.

All those extra spokes? A stem twice the length? Seatpost likewise? Different model year frame? Different forks? Variation in the local gravitational field? And perhaps it's not, perhaps it's just different scales. Why does it upset you so much?

Doesn't bother me - its clearly the scales thing, as there's no way it is [i]actually[/i] lighter. Merely observing.

Plumz - very pretty bike by the way. What is this year's?

doubt its lighter. Not a million miles away however. Swap round the cranks and kit will weigh similar will it not? Some of that KCNC stuff looks border line dangerous however.

Stunning bikes. I'm giggling and not even going to bother with a new bike now I've seen what really is available. The leap from a BSO like mine to these is far too great.

PS, Richard would you like to swap bikes at the rounds of the FNSS I'll be doing 🙄

Why do some people have all these doubt about which bike is lighter?

Sat on a forum how on earth can anyone state that there is no way one bike can be lighter than another.

I've got a KCNC cockpit on my Tuareg and it's fine.
Their bits are beautifully made, very light and I've not died in the 18months I've ridden it.

Either way the Anthem frame is a great start to build an unfairly light bike - anyone riding one clearly needs to carry bricks to even things up a bit.

Sub 22lbs

I love that you can't have a weight weenies thread without people arguing about who's is lighter 😆

Of course you can't, it's just incomplete otherwise!

Either way the Anthem frame is a great start to build an unfairly light bike - anyone riding one clearly needs to carry bricks to even things up a bit.

Lovely bikes as they are, are the frames not considerably heavier than a Spark/Epic/Top Fuel, thus making them quite unsuitable if you're purely chasing weight!?

I thought the Anthem was just over 5lb for the alloy version. The lighter weight's reported for Spark etc are usually the carbon versions at just over 4lb?

Isn't the carbon one virtually the same though? In fact the first incarnation was heavier IIRC.

I think a Spark frame is 3.9lbs, and I seem to remember my Top Fuel was something like 4.35 including seat mast/post.

So yes.

This is my new build, On One Dirty Harry 29er, 21.4lbs.
The stem is now lowered and brakes lifted.

Liking the Dirty Harry. Impressive weight considering the XT cranks, Rebas, Hope brakes and sensible pedals.
