Michael, OK, I'm ashamed about considering the wheels in an attempt to keep up. Most likely, I wouldn't buy them (I'm riding Mavic Open Pro's) but the idea of less weight makes sense. I've handled some Zipp 303's in my LBS but they are tubular rims. That's why I was exploring the internet and saw the Topolino wheels. If I were to really buy into this, I'd get the lighter wheels, the Zipps.

With regard to the "myth" of lower rotational mass, Its true that it exits, but perhaps a myth that it makes any difference. <snip - Ah I see, thats what you are saying with many words and numbers |

I would take that as a poor way of saying that the carbon is for structural strength (stiffness of the wheel) and the kevlar is to protect the carbon from damage, making it tougher. I can't similarly translate "dampen road vibration" to something plausible. -- Ignorance killed the cat. Curiosity was framed. |

It is the best way of saying that the carbon is there to slow down the creep of the kevlar. -- ================== Kraig Willett www.biketechreview.com ================== |

It is the best way of saying that the carbon is there to slow down the creep of the kevlar. I think it is just like the Spinergy PBO's design. They use a plastic coating to protect the carbon. Spinergy states that the spokes can handle scratches but if the plastic is penitrated or cut through then the spoke should be replaced. This design looks like it uses the Kevlar to coat the carbon (and also use it to form a bladed spoke). So the original comment is correct but it is not a leg puller but simply the truth. The carbon is the load (or should I say tension) bearing material and the Kevlar simply protects the carbon (add toughness). Spinergy solves the same problem using a plastic coating instead of Kevlar. JBP |

That sounds familiar: http://tinyurl.com/c6ct ;-) No carbon that I know of in the PBO/SPOX spokes, either. -- ================== Kraig Willett www.biketechreview.com ================== |
