Anyone ever use them?
Curious, the sell a chromo-moly flywheel that's supposedly stiffer than aluminum and better etc?

To be more exact

 

They are just quoting general material properties: size-for-size any steel is about 3x stiffer than any aluminum; steel parts can be designed for infinite fatigue life where aluminum can't be; wear depends a lot on surface hardness but if an aluminum part is anodized then it will wear well.

Stiffness in a real life part depends on it's shape too, not just the basic material property. Notice how aluminum flywheels are solid while this steel one has spokes; maybe they are the same stiffness under load?

Anyway, it looks like an interesting alternative that I would consider, I'll bookmark it for future use.

 

Yea, something I'll try out sometime. Seems nice

 

Action clutch is a stand up company. I won a clutch in a contest and have yet to use it but the support and people are awesome. Bisi of Bisomoto uses action clutch, yes they can stand up to the pressures of high HP.
