magnesium wheels for street?

Sounds like Oz wheels has some explaining to do.

[Speeddog]

OZ has just received about $3M worth of the worst advertising one can imagine. 

It did fail adjacent to the caliper, perhaps the spokes were dragging on the caliper.
But that would mean some other problem had occurred, bad wheel bearing or such....

[Spidey]

It almost doesn't matter what OZ says now.

I really can't imagine running mag rims in a race environment for 4 years.  Even at a club level, you've gotta start thinking about replacing them at that point.  OTOH, only a few races?

OK - were those mag OZs or forged AL OZs? Because I thought they only made aluminum wheels.

Even so, really bad publicity for them. According to marketing literature they are supposed to be very highly engineered and tested. There has to be some explanation for what happened other than just 'OZ wheels are fatigue-prone and weak'.

Also, I remember the OZ wheels as being made by a different company, and OZ bought that company. Motowheels could tell you more about that.

On the bright side look for cheap secondhand sets of OZ wheels for sale on the Bay. Not that one would want to risk it...

Another argument for BST FTW

Magnesium.

Magnesium OZ = 6 spoke.

Aluminum OZ = 5 spoke.

Magnesium.

Magnesium OZ = 6 spoke.

Aluminum OZ = 5 spoke.

well maybe they need to go to 7 or 8 spoke

Folks that's what you can expect out of a Ducati superbike. Just TOO MUCH POWER.

[live2ride]

what is impressive is the power of the bike as well as the traction the wheel was able to achieve.

[chixstrip]

Hooray for SSA that the wheel bounced clear of the bike.

I have a completely inexpert opinion, but this being the internet I will now share it with everyone as if it were gospel:

Seems strange the spokes broke in the same place on every one and all at the same time. Even with something as brittle as mag I'd expect a slower failure (maybe one spoke going first) with lots of vibration and warning to the rider before the rest gave out.

Therefore this was caused by something hitting the spokes.

[Raux]

I would expect OZ's PR arm to start the push for damage from outside not an internal failure. So I am sure OZ will be the first to announce the cause if that's the case.

If it's an internal failure, then I expect the team to push the findings.

Every single forum posting should be preceded by this.

not to be a voice of reason, esp. on the internet, but none of us are racing this equipment such as it is designed to be used and was in the case of the wheel breaking.  the truth of the matter is no product is 100% fail proof in the extreeme conditions of racing.  For all of us desktop racers on the internet know this wheel could have had something bouncing against it in a race semitruck for the last 2 months or it was a prototype wheel.  If I had the money and NEED would i buy this product; hell yeah.  2 cents cha-ching
