Forget puppy killing with your fixieeee bike
Carbon bikes kill mice
"Tests on mice suggest that exposure to carbon nanotubes could lead to cancer of the lining of the lungs."
"carbon nanotubes could be the new asbestos"

If I rightly recollect:
Determining the toxicity of carbon nanotubes has been one of the most pressing questions in nanotechnology.

Results from various scientific tests on carbon nanotubes have so far proven confusing, with some results indicating it to be highly toxic and others showing no signs of toxicity. This is primarily because of difficulties arising in spotting the nanotubes entering the cells from other carbon-based cell structures such as membranes.
*never heard of Wikipedia face*

my bike is not made of nanotubes, therefore i am not worried.

See dale i told you that bike was a killer... a mouse killer to be exact.

I feel a new lfgss slang word has been born...

BMC riders of the world are shitting themselves. Serves the flash cunts* right.

I am definitely not jealous of BMC owners.

I read one should never drill, cut or sand carbon components withouth proper breathing apparatus...

I don't use carbon so no issue...

Damnit! I touched Dale's bike last night. You'll have to put a warning on that thing.

"Inhalation of carbon nanotubes would be at the source of manufacture, not in finished items."

HTFU

my frame was made in taiwan, so i'm actually trying to help the exponential population growth in asia!

Unless you are doing things like trimming your CNT carbon bars (Easton) down to size, something I have done a few times !

I wonder what level of exposure is considered hazardous ?

Keep it wet when you're cutting, and if you start sneezing, stop breathing....

That place could do with a woman's touch

It's too late for me gabes, I fear I have already cut my last pair of handle bars down. If they ask tell them I want to be buried in a hip hop slave coffin, it should be fluro green with an orange lid and red lining, I don't want any religious symbolism on the lid, you know, no crosses or anything, but if you could see your way to getting a chrome NJS logo on there that would be cool, also ask them to put Oury grips on the handles for the pallbearers, white would be nice.

^^^dogs turned into a roadie...wtf!?! how fat are your forks! they look like TT aero forks

originaly wanted to cut my carbon fibre bars narrower but was worried bout the loose fibres. i didnt bother cutting it but in my research, ive read that the best way to do it is tape up the bit you want to cut and keep it wet. and of course wear eyewear and dust mask whilst cutting

nanotubes http://en.wikipedia.org/wiki/Carbon_nanotube

carbon fibre http://en.wikipedia.org/wiki/Carbon_fiber

not same. although you still shouldn't inhale carbon fibre.

All my Easton bars have definitely been CNT (I think it is supplied by Zyvex to Easton) - So these are the killer bars !!!

Aids Bike

Ah go trim your CNT!

I've been using carbon nanotubes all week in the lab. Everyone in the industry knows they're like asbestos on steroids, which is why we handle them in a glove box in a 1K clean room. But that BBC story is a classic case of them jumping on the release of a paper and making it sound like shock news.

Carbon fibre is still fucking bad for you too when you break it (this has also been known for ages, even the monkeys on the shop floor at TVR got twitchy when I started cutting some up with scissors ;)), you don't want to be getting the power tools out around that stuff.

CNTs in consumer products like tennis rackets? Can't see the point myself. Theres loads of things they *might* be useful for, but sticking them in 'dumb' structural products with today's expertise is likely to be nothing more than a marketing gimmick.

Nanotubes are stupidly expensive and are not found in any Bicycles components or frames. To put it in perspective. 50 mg of Nanotubes are selling in raw form right now for 350 USD. Add to the fact that no one in this industry knows how to use them and all you're left with are marketing lies.

By the way, if you ground up any frame or component material to a dust and breathed that in, it would kill you.

No-one would pay that much. You can get high purity (>90%) SWNTs for about a twentieth of that price. Buy more than a few grams and you can get it even cheaper.

Easton handlebars have had CNTs in them for years, as have their forks and their seatposts and I think their wheels and their seat stays and their stems.

I have two handlebars and a set of EC90 forks in the same room as me right now, they both use CNTs.

C_NT.. . ha ha ha is that what kills mice and men... ahhem i off.

Easton CNT - I smell marketing wank.

And marketing wank it is... even if Easton used nanotubes in their bars, which they don't... what would be the point of a couple grams of nanotubes in a 200 g bar apart from making the price astronomical.

on their website http://www.eastonbike.com/PRODUCTS/T.../tech_cnt.html it seems to be something about filling in the gaps between carbon fibres with CNT's rather than resin, which is assumed to improve strength.



note: the page cites no actual evidence that this is effective at adding rigidity.

Ha, you should see the research paper I have from a japanese group researching copper nanotubes... "CuNTs" is scattered libereally throughout :D

Ah, a diagram.. Must be true then.....

Seemes the right place to post, HKFixed beat me to the jump on the 103g seat/post combo but this fella in Finland made his own carbon TT frame in his kitchen and blogged everything..

http://www.signature.fi/cf.htm



and he did a 100g version too

So what! Connie and Ken made this bike out of toilet roll tubes...

i bet Ken chose the colour !!

lol.

CNT = Carbon Nanotube Technology = does not contain nanotubes

They may be filling the gaps - pointlessly - but it's not with Nanotubes unless there is a market for £780 handlebars that I'm not aware of...

I particularly like the graph where they show how strong a nanotube is compared to regular carbon but don't actually show what the performance difference between their regular carbon and their CNT carbon. What about a real world test.

I'm really fun at parties...

CNT = Carbon NanoTube

Well, if someone's willing to send me an offcut of their fancy pants CNT handlebars I'll throw them in an SEM and we'll see what they look like.
