Show me your lightweight XC speed machine

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 2×9 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?

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.

Doesn’t bother me – its clearly the scales thing, as there’s no way it is actually 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!

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.
