carbon fiber bike?
Whats up, i'm new here. I'm a former bmx bike guy who's now into cars, but i'm lookin to sell off a few parts and buy a new bmx bike since i miss riding.. i was wondering if there's a company that makes carbon fiber bikes? or frames? I searched on google and all i found were 'road bikes' in CF, but no BMX bikes. Do such bikes exist?

If there is little reason to save weight in BMX style riding why would someone bother to fabricate a frame in carbon fiber?
Just a thought...

maybe its just me but what you just said went right over my head :\
the only explanation for a lack of cf bmx frame is because its too much money to make one that would be worth someones time...for racing would be the only use i could see one but most still ride the cromoly or aluminum frames because i think its easier to ride soemthing that has some weight so its more stable. thats my 2 cents

carbon fiber frame would break. its as simple as that. also it would cost an arm and a leg. besides, you could just buy a really nice stricker or similar light frame weighing in at just over 5 pounds, and they are strong as hell

LOL! yea that would be horendous you just start landing your record breaking 20 ft jump and you so pumped from the 360 you just pulled off.
Then comes time for the landing.
CRRRAACKKK!!!
anyways its a good iea if ur rich and just liesurely liek to cruise along roads with no serious frame pounding manuevers.
Man a carbon fiber biek would be FAST!!!!!

You could make a carbon bike strong enough to do BMXing, and it wouldnt be that heavy, but the material is soft and scratches easily. A deep scratch is like "please tear long the dotted line", and will be the focus for a stress fracture. If you are slamming your bike against concrete ramps or wiping out on a rough surface, you want the toughest material out there, which is either steel or titanium.

actually, GT, mongoose and supercross made CF bikes in the mid 1990's, good luck finding any info on them though. i remember when BMX plus! tested the supercross frame it broke because it wasn't full CF. they used CF tubes bonded to steel "lugs" like on a giant cadex carbon frame. anyway, it didn't really technically break, it just kind of, pulled apart in mid-air because they decided to use some stupid bolts that pierced the CF, and also there was residue on the steel part that was inserted into the CF part.
the mongoose frame was an injection molded one that actually did fairly well in races and such, i forget who their top pro was at the time, brian somebody (not foster). it was a pretty good frame. it was called the stealth.
the GT carbon fiber was a CF/aluminum frame. the front triangle was injection molded CF and was bonded to an aluminum rear triangle. the chainstay/bottom bracket joint looked like old auburns. i think some guy they used to call the lumberjack, i think his first name was either gary or greg, rode it in races and stuff. it held up pretty well too.
anyway, i remember seeing the supercross frames (after they refined them) at a local shop and kinda laughing about how they just fell apart. and i'm pretty sure the mongoose made it into production too. it sold for around $500.
i can't find anything about CF BMX frames either, just a brief blurb here or there about the stealth on google.
i think everyone stopped making them because they cost too much, not because they broke.

in case anyone ever doubted the existence of a carbon fiber GT frame, here is an auction on ebay: https://cgi.ebay.com/ws/eBayISAPI.dll...category=22677

i remember reading in mountain biking magazine, or mountain bike magazine or one of those that there was a guy out in california that made his own CF mtb frames(this was like 3 years ago though). It wasn't a cover story but it was a good 2-3 page article on the guy. CF is actually a really strong material if the weave isnt broken but thats not very practicle for a bike frame so companies have moved onto titanium.

I wonder if those guys realize that carbon fiber is stronger than steel and stiffer than aluminum. However Titanium is lighter than Aluminum and flexes like steel, so it has the best of both worlds!!
The GT carbon frame was DAMN nice, I've ridden a few, and its like every other GT race bike, tight in the corners and solid coming out, just how a race frame should be. The one Huffy CF I rode was nice but I was scared I was going to break it, not because it was a weak frame, but because I had recently broken my GT pro series!!
