thats sweet... i wonder how much those rims would cost. I know that JGTC use's Carbon Fiber rims IIRC.
you wont know till you drive on them for a few years...i call a failure on this product. Theres no way it can hold out better than other rims.

sorry chief that is static pressure
CF does not BEND. It breaks! So all those rims that have been bent by a pothole/curb etc..... if they were cf they would have SHATTERED as once you exceed the CF's capability there is ZERO give. It becomes a catostrophic failure.
i agree with you figgie, but you have to consider if they are selling this product, then they have thought of such things and have found ways to deal with or compensate for that.
it would be the end of there company if they put out a product that someone had a roller over at high speed because they hit a pot hole and the rim obliterated.
I do belive though depending on the weave and the construction precess some CF has a little bit of give to it.
CF has a great ability to absorbe enery and a circle is a very strong structure. Maybe it is not paosible to bend them but only crap them since they have a Mag core
They are using the stuff to make air craft wings which have to be able to bend and take a huge load before breaking.

look at the pics... its kinda obvious in the ones at the end...you can see the carbon fiber. its the whole outer rim.
Somehow, if i understand the properties of carbon fiber, i think the fact that they would fracture instead of bend is a bad property....but if you smack a curb or a pothole big enough to overwhelm the supporting mag spokes and allow enough flex to break the CF rim, i think you'd have a bent rim if you went with a conventional material, in which case the rim is screwed anyway. the spokes probably give considerable strength to the CF; and as someone said...circles are very strong shapes. in order for the CF to break, the inner circle of Mag. spokes has to give enough for that to even happen. unless you are thinking the ground will overcome the rubber of the tire and directly contact the CF, in which case i could definitly see the CF breaking...but if you have a decent sidewall...not huge, but moderate and not really thin i think it'd be ok....maybe. i dunno.
then again if you had larger sidewalls and the bead of the tire pushed up on the rim hard enough, the beads (or bead if not offset) would break off the CF portion that IS supported by the spokes.... what i mean is, anything to the sides of the spokes. whatever i'm rambling.
it would suck if you had a small hairline fracture and it caused a leak....what can be done to "seal" or "weld" CF? anything?

Clip: Spun alloy wheels will deform and fold up to a point then the centres will break, Cast aluminium wheels will explode with a big enough impact.
These CF/Mag wheels will act like a cast wheel but would probably take 2>3x the impact before they'd break.
(this is just a guesstimate on my part and makes the assumption that there's been some real engineering gone into them and they haven't been cooked in someone's backyard)
