I searched, hopefully not a repost.

 

Sick!!!!! Would have to be track rims only because I would hate to accidently curb them.

 

I've heard of this but never seen close up pics. Thanks they're amazing.

 

they must cost a grip

 

Are they directional? I wonder how that works.

 

starting at 2000 per wheel for 18x8...
and 18x8 is 12lbs

 

$2Gs a wheel?!!!!

 

droooool CCX mmmmm

 

Dymag makes a lot of cool CF wheels for bikes as well.

 

Wow thats pretty awesome.

 

These have been posted before....although I don't think it was on this site.

Next I'm sure we will get a few comments saying "track only, don't run them on the street" and "Cf is brittle", etc...

If you start to look into them....they claim the tests that have been performed on the rims show them to be sturdier than any aluminum wheels out now. And yes, even more resistant to curbing than aluminum.

They say the weakest point of the rim is actually the magnesium spokes. I think magnesium doesn't hold up to wear as well as aluminum, but I could be wrong.

Bottom line is, if you had the loot, you could run these on the streets without a problem.

 

Well, let's see...that CCX is what, $600,000? Mere pocket change, my friend.

 

12lbs That is LIGHT as a feather. Definatley worth it for $ 2K.

 

i think that 12lbs mainly from the magnesium center... b/c dry carbon weighs barely anything...
if they can somehow make the center c/f it'll be maybe 5-8lbs?

 

first one looks like a spare tire. I personally don't care about the looks.

 

Well, I learned from having Ti struts on the street that Ti may be stronger than steel.. but everything has a breaking point.. it's how they react to the breaking point that matters most.. steel and aluminum just bends and is graceful at destruction.. but Ti seems to shear when it reaches it's breaking point..

I'm sure it's the same with carbon fiber and magnesium wheels.. I'm guessing it'll work but over time, the fatiguing from street use (potholes, road debris) will eventually cause catastrophic failure..

For some reason I remember somwhere descibing CF as something that doesn't fatigue.

I don't know. To tell the truth, I'm 100% comfortable with the Carbon fiber; I'd run it in a heartbeat if I had the loot. It's the magnesium that I have problems with. Everything I've read says that magnesium doesn't wear well with age.....

 

I agree I don't think manesium alone would be strong enough. The rims on my Talon are made of magnesium and aluminum

 

hmmm..looks interesting..i'm impressed by the weight but not much by the looks because i do care about the looks

 

Ya, Carbon fiber doesn't fatigue, not as it brittle, it's small amount of flexibility is using on f1 and indy racing and the complete suspension. They use it's small flexibility and the complete suspension travel (like 2")
EDIT: are there any other styles of the rims
