I've been scouring eBay for damaged but repairable carbon frames, trying to get a bargin.
Thing is when you ask for a weight they all seem to be 1kg+ even when listed at 850gm by the manufacturer (I've not come across a supersix nano or whatever it's called).
Is there anything genuinely this light out there?
BMC winning the porkie pie contest with 850gm actually being 1150gm, a mere 30% lie.
Scott Addict SL is genuinely 800 odd grams in size 58, at least mine was.
Scott CR1-SL is about that as well.
I presume that manufacturers weigh frames completley bare. Without headset bearings and cups, seatclamp etc. Are the frames being weighed in the same stripped down state?
They weigh several of the smallest frame they have, then pick the lightest, they *only* weigh the actual carbon bit and the stuff that´s bonded to it. And they either weigh it unpainted or with the lightest paint option. So for some frames they'll be missing cable guides, seat post clamp and both mech hangers, which is something like 75-100 grams. Going from a simple single colour black (or bare/lacquered) frame to a gloss white might be another 300 grams.
Only way to really tell how much a frame actually weighs is to buy one and weigh it.
Or alternatively, your sellers might be quoting measured weights including bottom bracket, or headset, or seatpost?
Good info re Scotts ta.
My 2009 CR1 is ,1kg (bare, 57) so that makes sense.
I recently got a BMC SLR01 claimed weight 849gm, weighed 1300gm with the seized seatpost (and BSA BB adaptor) in 🙁
Don't forget to factor in the extra weight of the spoon, too.
also factor in the lead to get it to minimum UCI weight 😉 no point making something so light that you're going to have to add too much to it...
There are a lot of those CR1 SLs around from when they were punting the framesets out for £500 a few years back.
Love mine.
Are they also quoting for the fork, frames useless if the forks not attached.
Most light production frames are indeed 750g-1kg with/without forks, forks weight in at about 350-400g so a 750g frame and fork will be 1100g thereabouts ....
Simple eh.

Sounds about right, seatpost 250g, seat clamp 25g, BB adapter 50g, is 975g. Did it have a headset (100-120g) or internal cables still in?
TINAS - nope, seatpost is superlight, I'd guess <200gm. no headset, no seatclamp, no way a plastic bb guide is 50gm.
Thanks for your input though 😀
TINAS - nope, seatpost is superlight, I'd guess <200gm. no headset, no seatclamp, no way a plastic bb guide is 50gm.
If it's stuck it's presumably aluminium, if it's aluminium then significantly <200g is optimistic.
Take it out and weigh it. if you're going to be weight weenie, you have to do it properly, spreadsheets and all! Manufacturers bend the truth, but it's not really fair to say it's a lie if you've not stripped the frame don properly.
My 2006 Giant tcr advanced in the clear laquered option is genuinely 920g with seatmast but no clamp.
Super six evo himod 695 gm
Not sure I'd want a repair one.

Honestly, do you think I am stupid? Why do you insist on coming in with incorrect assumptions as if I don't know the answers, when I'm the one looking at the frame?
It's a carbon seatpost, propriety, on their flagship bike. 200gm is realistic. And it's seized in.
Blimey Al, bad day at the orifice? 🙁
What kind of repairs are you looking for? By the time you've fixed a broken stay you might have added a couple of 100g.(I'm no expert, i don't know how much a repair weighs)
There must be a Chinese carbon copy on Ali or eBay etc that fits the bill. I think I'd prefer to ride a generic Chinese copy than a home fixed repair frame off eBay that's over 5 years old.
Its why they give them secondary names, evo, pro, advanced, SL etc.
The weight quoted in the cycling press will be for the top model that nobody buys whilst the bike in your LBS is the 2nd or 3rd tier still probably called "advanced" but it bit more portly. The third tier may also have fewer features, hidden seat clamp etc.
It cynical or marketing depending on your view point.
for me the cycnical bit is the press write up..
" The new Fandagio Supersport weighs in at a super light 800g and whilst the top model is £9000 the range starts at £1500" But it doesn't really cos the base model is different frame altogether.
Worth remembering when you come to the repair that lightweight cutlery is manufactured for airline use, though I only ever see the plastic stuff these days. Perhaps someone who turns left when boarding can help you out with some samples.

Giant Defy Advanced SL frames are the lightest frame Giant ever made. Watch the seatpost has not been cut too short.
They won't be cheap!
Have you looked at Trek Emonda, friend i ride with bought a frameset at £1400 to build up and he has built a 6.6kg bike using standard not too weight weenie parts, the frameset weighed 1.58kg with forks, headset and spacers as it came from memory
Honestly, do you think I am stupid?
Do you really want an answer to that 😆
By the time you've fixed a broken stay you might have added a couple of 100g.([b]I'm no expert, i don't know how much a repair weighs[/b])
Then why make up a figure? That's exactly how misinformation spreads! 😉
I don't know how much weight a 'normal' repair would add either. (but I doubt it's as much as that). Anyone here actually give us an idea?
BMC winning the porkie pie contest with 850gm actually being 1150gm, a mere 30% lie.
I think that once you take your seatpost and BB adaptor out of the equation the Planet X Galibier might win that prize, admittedly it's not carbon, but Alu, and this is directly lifted from the speil on their site:
(been previously quoted as 995g)Sub 1kg frame weight
But most people who've actually had one in the flesh say ~1130gm, not denying it's light for an Alu frame but certianly not <1kg as claimed*. At least with carbon the claims are believable [s]lies [/s]marketing figures.
*yes, yes they probably mean they found one example fromt he factory, in a child's size, and with no paint on that weighed that, but still a big fib in reality.
Chinese?
My Deng Fu FM208 is 920g (actual), and that’s painted, I suspect a ‘bare’ lacquered frame would be lighter.
Did you say broken Scott cr1 in 56cm?
http://singletrackmag.com/forum/topic/fs-scott-cr1-sl-frameforks-100
Thanks Damascus.
1.58kg is podgy.
My 56cm Bianchi frame is 1050g and fork is 350g 🙂
I am 89.5kg 🙁
I have a 56cm Scott Addict. I weigh and measure all sorts of stuff as im interested in it....
So, the frame with headset, top cap, forks, BB, bottle cage bolts, mech hanger, seat clamp, weighs 1330g. The forks weigh 334g. So the frameset with bb, headset etc weighs 996g.
I didnt include the steerer spacers.
It makes a great lively single speed fixed gear bike using an eccentric Eno rear hub, DA chainset, and carbon finishing kit.

Felt Frd frame 684g verified 😯
I just spotted this bike on [url= https://www.ebay.co.uk/itm/planet-x-pro-carbon/253212744833?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D48785%26meid%3Daa5a4e22f1944126b5cd2d38a3acf5e6%26pid%3D100005%26rk%3D3%26rkt%3D6%26sd%3D253223141801&_trksid=p2047675.c100005.m1851 ]EBAY[/url] and thought of you, it'll be much lighter than most.
needs a small repair.
😀
That eBay frame is perfect if you have the lower attachment.
How so njee?
Workswell WCB-R-066 (same geo as a Cervelo R5) is worth a shout if you look at Chinese bikes.
51cm is 800g, my 56cm was 1029g including the ridiculously heavy metal BBright BB they had installed (can't remember the weight of that when I removed it, but can track it down if you're interested).
There's a huge weight weenies thread dedicated to it, and both I and CH race on them.
Well when I bought my Giant TCR SL2 I asked them to put it on the scales, being sceptical on what the weights are usually said to be, and with everything bar the pedals, it came in at 6.8kg - with alu bar and stem. The frame is bonkers light and great on the road (just as comfy as my old "endurance" bike). There are some great deals on 2017 TCR SL bikes now...
Try looking for a Cervelo R5. My 56cm 2012 frame was 760g as it arrived, with hanger, bottle cage bolts, seat clamp etc.
Should be a few around as there was a good deal on these for a few months just before the new R5 shipped.
Is the mega light Giant?
I had one of those. Light it was not. However, it was fabulous at being totally dead, slow and uncomfortable.
The "Composite" line was Giant's budget get-you-on-a-carbon-bike line. They were not that light and discontinued now. You want "Advanced" or "Advanced SL" grade frames for lightness.
You're probably best off ignoring anything that comes with a proprietary seatpost, like that Giant, as they're usually double the weight of normal carbon one.
If you're looking for a damaged frame to repair, how would a Parlee ESX work?
I've got one with a broken seatstay which I was planning to get repaired and build up... could let it go for the right price
Thanks again all!
My Dengfu R02 in 58 is 940g, matching fork is 320g. I think they had a light option as well but at 80kg and a Chinese frame I decided to play it safe
I built a size 54cm FM 066 (Hng Fu) up with Chorus, power meter, alloy bars, stem etc. to 6.4kg, albeit on 24mm carbon tubs, but it wasn't dear at all.
Individual weights (by me) were Frame 882g Fork 372g Seatpost 190g
I had a Hongfu FM66 SL, sub 900g. 16lb built up with some of Microshift’s top groupset and sensible components
