Nice PIC Nathan, and thank you for posting it so quickly too.

Is there anyone other than me out there who, though I really admire the visual and overall design of this hub and wheel, questions whether the mechanical design is going to allow too much flex between the central bearing housing and the outer rim? It seems to me that those tangentially curved spokes are going to flex a lot more than a radial spoke design will. It is not like this flex is going to be a problem right away, but after several million revolutions with the load of a heavier skater on them, I suspect we are going to see some nasty hub disintegrations, as the cyclic loading cycles and crack propagation properties of the specific aluminum alloy they chose for the hub eventually converge at a future point of impending failure.

I must assume that mechanical engineers used some kind of stress analysis to make sure this would not be an issue, but my gut feeling tells me it seems risky.

I never heard of any problems with Crossfires, and their hub is very similar...

Yes similar, but the Turbo spokes are a lot less radial and longer.

Thumbs up But remember Stacy Peralta?George Powell???????

This skate company Skate ONE.Bones/etc. RollerBones

They are the OLDEST and smartest and best equiped skate company in the WORLD.

They even make there OWN urethane. Machine shop is the most modern in the skate world. MAZAKS,Catia Design. Ever machine is MIL SPEC ISO.

They invented the urethane wheels AND BONES BEARINGS. (George Powel)

They have been at it since the 1960's. And they are (EPA) Grandfathered in anything they want to do. Northeren Calif by the sea. Look at the SB on there wheels. Santa Barbara. If your good looking go there. Second best climate in the USA..

They have been MAKING BONES Skate wheels for years. 103 Elites are prized by the artys.

I can assure you if your a doubter about the design???? Its a proven catia and then transfered to a MAzak. You can accept the program with out backup checking.

I did some stuff for them about 5 years ago and was shocked at the degree of quality they can do. They will not accept anything but the best. They don't have to.

There Skateboards are the best in the World.

Rent Dogtown Z boys and see the history.

Question Are Any Of These Wheels 40mm Wide...

That's the only thing that would keep me off a set of 97's!

The Snakes, Koi, Zebras and Roses are 40mm wide. Dunno about the Turbos.

I'd look online to tell you how wide they are, but skate shops have an ugly tendency to post assumptions as measurements. The funnier thing is that skateboard shops are now carrying the Powell/Rollerbones wheels, and they have an ugly tendency to assume the wheels are the standard size of skateboard wheels.

I think Nate's got them listed at 44mm wide on his website.

You know, they are more like 42mm. I'll look tomorrow.

I haven't skated them, but I have held them in my hands for a good bit. Yes, the "fins" or whatever people want to call them look a little thin, but I didn't see anything I thought would cause a problem. I don't know if they used simulation software to test them, but given their history, it's a safe bet that they did.

May bee the fins as they are called are designed to have a bit of flex or compliance.
Compliance in the rim/ hub could mean that the tyre can be made hard without
compromising ride comfort>

Do we have any reason to beleive that these wheels would feel "softer" or "harder" than most other 97's? I don't think I've been on anything "softer" than a white Shaman in the last couple of years...should I even be considering these 97 Bones?

They are made by bones not hyper. they are most likely baked for as long as an aussie scott tyre. I said most likely because im only guessing but i have skated bones speed wheels from the eighties and they rolled good.just the price is going to make or break em.of

I reckon you are on the money here, hub design can definitely affect the way a wheel handles.
From people I trust to know what they are talking about, these sound amazing.

And from all reports the 97A (I think they are 97 not 96) things are noisy!
